Although not always explicitly stated in the NetScout nGenius hardcopy and online documentation, the word probe includes such devices as external NetScout and Cisco SwitchProbe devices, internal embedded Cisco Catalyst 5000 and Catalyst 6000 and 6500 series Network Analysis Modules (NAMs), and mini-RMON switch ports.
Page 2 of NetScout nGenius Real-Time Monitor 1.4 Release Notes describes the suggested limits for physical interfaces as 50 active probe physical interfaces and up to 10,000 active switch ports.
RTM Release 1.4, as provided by Cisco Systems, does not impose hard limits on the number of physical interfaces you can add to the nGenius Server. However, with a minimum system configuration, it is recommended that you follow these guidelines.
The following sections contain important information that you should read before starting the installation:
Caution While every precaution has been taken to ensure that all nGenius directories, files, and the runtime execution environment are secure, you should limit unprivileged local login access to nGenius server systems to trusted users and disallow remote login access by privileged accounts. |
During installation, RTM automatically creates the secured user ngenius. All RTM files are fully accessible (with read, write, and execute permissions enabled) only to an administrator logged in as the secured user.
You can protect RTM by limiting access so that only systems with valid needs can access it over the network. To do so, place an access control list (ACL) on a router between the RTM server system and the remainder of the network.
It is critical that you use only the supported Java plug-in versions listed in NetScout nGenius Real-Time Monitor 1.4 Release Notes and NetScout nGenius Real-Time Monitor 1.4 Installation Guide.
Caution If you use any other version, system behavior is not guaranteed. |
The RTM client is supported on these platforms:
Note OS patch 107153-01 is required for Chinese OS running on Solaris 7. |
TimeSaver If you are not using Cisco TrafficDirector, you can skip this section. |
Because only one network management system can control configuration of shared RMON devices, you must decide if you want RTM or TrafficDirector to control device configurationbefore you log in and start configuring devices.
Note For optimum performance, you should install RTM on a dedicated system on which TrafficDirector is not installed. |
To use TrafficDirector to configure all devices, you must add the parameter nGenius.nsminuse to the server.properties file. This parameter tells RTM that TrafficDirector is configuring devices and prevents RTM from applying global settings and templates to those devices.
To use TrafficDirector to configure only some devices, you must change the write community strings on the devices. If the write community strings do not match, the write community fails, and the nGenius Server cannot write global settings and templates to the device.
The type of data generated in history reports depends on which application is configuring devices. Each application collects data only from those devices for which it controls configuration. Therefore, if you want RTM to control device configuration, you cannot use TrafficDirector to generate reports at the same time.
By default, RTM automatically configures all devices you add to the nGenius Server by applying global settings and templates to the devices. If you want TrafficDirector to control device configuration, you must modify the RTM settings.
TimeSaver You should make these changes before you add devices to RTM to eliminate the step of reconfiguring the device in TrafficDirector. |
Step 1 On the system on which the nGenius Server is installed, go to the $RTMHOME\bin folder (on Windows systems) or $RTMHOME/bin (on UNIX systems).
Step 2 Use a text editor to open the serverprivate.properties file.
Step 3 Add this string to the file:
stealth.nsminuse=true
Step 4 Save your changes.
Step 5 Close the serverprivate.properties file.
Although other vendors' devices are listed in the NetScout documentation, Cisco Systems supports only those devices listed in Table 2.
Table 2 lists the devices supported by Cisco Systems.
Note For information about support for other devices, contact NetScout Systems. |
1200 | 2924MXL | 2950G-24-DC | 3550-24 | 3548XL |
The DSMON MIB is disabled by default. To collect DSMON data from your network, you must enable the DSMON MIB on the NAM. After it is enabled, you can view DSMON data with Traffic Monitor.
Note To view DSMON statistics with a Catalyst 6000 and 6500 series NAM, you must be running NAM software release 2.1(x). |
Step 1 On the system on which the nGenius Server is installed, go to the $RTMHOME\rtm\bin\admin folder.
Step 2 Use a text editor to open the serverpublic.properties file.
Step 3 Set the dsmon.enbabled parameter to true.
dsmon.enabled=true
Step 4 Save your changes and close the file.
Step 5 Stop the nGenius server.
Wait until all RTM-related processes are complete.
Step 6 Start the nGenius server.
Using a text editor, you can modify the parameter dsmon.aggregation.profile
as necessary. You must restart the nGenius server for the changes to take effect.
Table 3 shows the options for each aggregation profile.
Profile # | Aggregation Profile | Description |
---|---|---|
1 | Voice Profile (default) | There are four code point groups:
|
2 | One group profile | Code points 0-63 are in one groupGroup 0. |
3 | Four group profile | There are four code point groups:
|
4 | Eight group profile | There are eight code point groups:
|
5 | Sixty-four group profile | Each code point has a group. For example:
|
The VoIP software component allows legacy SwitchProbe users to monitor voice and video traffic traveling on your network. Only those devices that support VoIP are displayed in the VoIP Navigation tree.
To use the VoIP Monitor, you must have a minimum of 32MB of RAM in your SwitchProbe device and be running NSP 5.2 firmware. This firmware version is only available from NetScout Systems.
Note For NSP 5.2 firmware, you must contact NetScout Systems. |
The VoIP Monitor software component is not supported on the Catalyst 6000 and 6500 series NAMs and Catalyst 5000 series NAMs. However, you can use the Catalyst 6000 NAM Traffic Analyzer to monitor voice data. For more information on using Traffic Analyzer, see the User Guide for the Catalyst 6000 NAM Traffic Analyzer.
You must be running Catalyst 6000 and 6500 series NAM software release 2.1(1a) or later to use the SMON Monitor feature.
Note To view DSMON statistics with a Catalyst 6000 and 6500 series NAM, you must
be running NAM software release 2.1(x) with patch 2.0. This patch can be
downloaded from the following url: http://www.cisco.com/cgi-bin/tablebuild.pl/cat6000-nam |
Step 1 Log into the switch.
Step 2 Session to the NAM.
Step 3 Run the following commands from the NAM CLI:
autostart vlanstats enable
autostart priostats enable
Step 4 Reboot the NAM.
To configure the Catalyst 6000 and 6500 series NAM, you use the same procedures as for a switch. Traffic Monitor uses switch templates to establish default mini-RMON on the switch, and global settings to establish full RMON1 and RMON2 on the NAM.
This section describes how to use RTM to install basic functionality and configure the NAM so it is recognized and can be managed by the nGenius Server and clients.
The instructions in this document assume that you have already installed and configured the NAM with an IP address, subnet mask, broadcast address, and default gateway, and that ping requests from the system on which RTM is running are successful.
Note If you have not already configured the NAM, and you are running Cisco IOS software, follow the instructions in the Catalyst 6000 Network Analysis Module Installation and Configuration Note. The configuration information in this document is for Catalyst 6000 and 6500 family switches running Catalyst OS software. |
The primary function of RTM is to manage the RMON and RMON2 agents embedded in certain devices. To manage the Catalyst 6000 and 6500 series NAM with RTM, you must add the switch to the nGenius Server.
These sections provide more information:
Before you can use the NAM for network analysis, you must log into the NAM root account and configure the following:
To configure these parameters for the NAM, perform these steps in privileged mode:
Step 1 Enter this command to verify that the NAM is installed and that the power is on.
Console> show module mod_num
Step 2 Establish a console session with the NAM by entering:
Console> (enable) session mod_num
Step 3 At the login prompt, type root to log into the root account.
Step 4 At the password prompt, type root as the root password.
Note If you have not changed the password from the factory-set default, a warning message displays. |
Step 5 Configure the IP address and subnet mask by entering:
root@localhost# ip address ip-address subnet-mask
Step 6 Configure the IP broadcast address by entering:
root@localhost# ip broadcast broadcast-address
Step 7 Configure the IP host name used in the CLI prompt, show commands, and log messages by entering:
root@localhost# ip host name
Step 8 Configure the default gateway by entering:
root@localhost# ip gateway default-gateway
Step 9 Configure the domain name for the NAM by entering:
root@localhost# ip domain domain-name
Step 10 Configure one or more IP addresses as DNS name servers by entering:
root@localhost# ip nameserver ip-address [ip-address]
Step 11 Verify the NAM configuration by entering:
root@localhost# show ip
Step 12 Configure the SNMP syslocation MIB variable by entering:
root@localhost# snmp location location-string
Note The MIB variables in Step 13 and Step 14 must be valid DisplayString texts, each with a maximum length of 64 characters. |
Step 13 Set the SNMP sysContact MIB variable by entering:
root@localhost# snmp contact contact-string
Step 14 Set the SNMP sysName MIB variable by entering:
root@localhost# snmp name name-string
Note You can delete the SNMP location, SNMP contact, or SNMP name by entering the respective command without any parameters. |
Step 15 Set the SNMP agent community string parameter password for read-write access by entering:
root@localhost# snmp community community-string rw
Step 16 Set the SNMP agent community string parameter password for read-only access by entering:
root@localhost# snmp community community-string ro
Note Clear the SNMP community string with the snmp delete community community-string command. |
Step 17 Verify the SNMP access controls and settings by entering:
root@localhost# show snmp
Before the nGenius Server can communicate with a switch in which a NAM is installed, you must configure the switch and NAM in a specific way, using these guidelines:
For example, using the switch CLI command show snmp, you will see:
Community-Access Community-String
---------------- ----------------
read-only public
read-write private
Using the NAM CLI command show snmp, you will see:
community private write
community public read
Using the RTM Device Configuration feature, enter the switch name, switch IP address, switch type, and the read and write community strings established on the switch.
After doing this, the nGenius Server automatically learns and displays the ports, VLANs, FECs, and NetFlow interfaces configured on the switch.
To add a new switch to nGenius Server:
Step 1 Start RTM from http:// rtm-server:port/.
Step 2 Click Login (in the lower-right corner of the NetScout Products window).
The login dialog box is displayed.
Step 3 Enter the login name and password.
Step 4 Click Login.
Step 5 To start the nGenius Server, click the Server icon in the NetScout Products window.
Step 6 In the Device Configuration window, select the Switch tab.
Step 7 Click Add.
The Add Switch dialog box is displayed.
Step 8 In the Switch Name field, enter a name for the switch you are defining.
The name is case-sensitive and can be a maximum of 40 alphanumeric characters. You can use hyphens and underscores but no spaces in the name. The name must be unique; that is, you cannot assign this name to another switch.
Step 9 In the IP Address field, enter a valid switch IP address.
This is the IP address of the switch in which the NAM is installed and consists of numbers separated by decimal points (nnn.nnn.nnn.nnn).
Step 10 In the Switch Type field, select the type of switch you are adding.
For example:
Step 11 In the community names fields, do the following:
a. Read CommunityEnter the read community name established on the switch.
b. Write CommunityEnter the write community name established on the switch.
Note The read and write community strings installed on the switch must match the read and write community strings on the NAM. For more information, see the "Identifying Community Strings on the NAM" section. |
Step 12 In the Retries and Timeout fields, do the following:
a. RetriesEnter the number of times (between 1 and 32767) the nGenius Server should try to reach the switch if there is no response.
b. TimeoutEnter the length of time in seconds (between 1 and 32767) the nGenius Server should wait between each retry.
Step 13 Click OK.
This process might take approximately 1 to 3 minutes, depending on the number of ports in the switch and speed of the system on which the Server resides.
You can check the Task Progress Report for details.
Note The nGenius Server identifies the detailed configuration on a switch (in the Details window) after you add the switch to the nGenius Server. |
Step 14 Create a SPAN session:
a. Select the switch.
b. Click Spanning.
The Switch Spanning dialog box is displayed.
c. Select the SPAN source.
You can select ports, VLANs, or FECs as the SPAN source.
Note You may only select ports, VLANs, or FECs for one span session. |
d. Click Add.
e. Click OK.
You can now use Traffic Monitor and Packet Analyzer with the NAM.
The read and write community strings in the switch must match the read and write community strings in the NAM.
Use the show snmp command to display basic information about the SNMP agent configuration. The output from this command can help you debug communication problems.
The following is an example of the information displayed for the NAM:
root@localhost# show snmp
SNMP Agent: nam1.cisco.com 172.20.52.99
SNMPv1: Enabled
SNMPv2C: Enabled
SNMPv3: Disabled
community public write
community private read
sysDescr "Catalyst 6000 Network Management Module (WS-X6380-NAM)"
sysObjectID 1.3.6.1.4.1.9.5.1.3.1.1.2.223
sysContact "Jane Doe, Cisco Systems, (408) 111-1111"
sysName "6k-NAM - Slot 2"
sysLocation "Cisco Lab, Building X, Floor 1"
The following is an example of the information displayed for the switch:
Cat6ksup1> (enable) show snmp
RMON: Enabled
Extended RMON Netflow Enabled :None.
Memory usage limit for new RMON entries:85 percent
Traps Enabled: None
Port Traps Enabled:None
Community-Access Community-String
---------------- -----------------
read-only public
read-write private
read-write-all secret
Trap-Rec-Address Trap-Rec-Community Trap-Rec-Port Trap-Rec-Owner
---------------- ------------------ ------------- --------------
Trap-Rec-Index host.domain.com public 162 root@host.domain.com 1
Note The switch read-only community string matches the NAM read community string (public); the switch read-write community string (private) matches the NAM write community string. |
To use NetFlow Data Export (NDE) as a traffic source for the NAM, enable the NetFlow Monitor option so the NAM receives the NDE stream. The statistics are presented on reserved ifIndex.3000.
Note For more information, see the Catalyst 6000 Family Software Configuration Guide on Cisco.com. |
To enable the NetFlow Monitor option on the NAM:
Step 1 Enter this command at the switch command line:
set snmp extendedrmon netflow enable mod
Step 2 Add the switch to the nGenius Server.
Step 3 Start Traffic Monitor.
An entry called Netflow (via NAM) is now displayed in the switch port drop-down list.
Spanning is a mechanism used by the nGenius Server for monitoring individual interfaces supported by a switch. These interfaces can include physical switch ports (including access ports and trunks), VLANs, and FECs.
Step 1 Start Device Configuration if you have not already done so.
Step 2 Select the switch.
Step 3 Click Spanning.
A list of ports associated with the switch is displayed in the left pane.
To use the NAM, you must span a port, VLAN, or FEC to it. During spanning, data is sent to the NAM for analysis.
Step 4 In the left pane, select the port, VLAN, or FEC to SPAN.
Note A port list is displayed by default. However, you can view VLANs or FECs by selecting the appropriate tab. |
Step 5 Click Add.
Step 6 Click OK.
TimeSaver If you are not using Cisco TrafficDirector, you can skip this section. |
nGenius Packet Analyzer is a superset of the Cisco TrafficDirector Data Capture and Protocol Decode features.

Table 5 describes the problems known to exist in this release; Table 6 describes the problems resolved since the last release of RTM.
Bug ID (Severity) | Summary | Explanation |
---|---|---|
CSCdx40532 | RTM Task Progress Report does not always work. | When adding or deleting a device in RTM, the Task Progress Report occasionally does not appear. To work around this problem, restart the client browser. |
CSCdx56721 | RMI cannot be tunneled across HTTP. | RTM supports a feature known as RMI-over-HTTP tunneling so that clients can access servers behind firewalls. This feature does not work in RTM 1.4 To work around this problem, open all TCP ports greater than 1024 so that the client can communicate directly with the server using RMI. |
CSCdx56228 | RTM should change to a default RMI port other than 1099. | RTM currently uses the default RMI port 1099 which can easily conflict with CiscoWorks 2000. To work around this problem, if you see errors regarding RMI port conflict, change RMIRegistryPort=1099 to another port that is not being used (such as RMIRegistryPort=1234) in the following files: /opt/nGeniusRTM/1.3.0/bin/serverprivate.properties
/opt/nGeniusRTM/1.3.0/html/client.properties
|
CSCdx06011 | You cannot SPAN the same interface to two analyzer ports. | This is a known limitation. |
CSCdx03097 | Processes not starting if only the administrator has full control on the hard-disk nGenius is installed on. | Make sure the root directory has permission set to Everyone Full Control before you install RTM. The correct permissions will propagate down the RTM directory structure. |
CSCdx25484 | Adding a Catalyst 6513 switch displays an error when you select Cat_6513 as the switch type. | To work around this problem, when you add a Catalyst 6513 switch running Catalyst OS software, select Cat_6509 as the switch type. |
CSCdt37031 | RTM does not have a command line installation for UNIX platforms. | This is a known limitation. UNIX platforms must have an X display with at least 256 colors. |
CSCdx56265 | NL/AL Hosts and NL/AL Conversations are disabled after upgrading. | NL/AL Hosts and NL/AL Conversations are disabled for SwitchProbe interfaces after upgrading RTM from 1.2 or 1.3 to 1.4. To work around this problem, if you don't have many SwitchProbes in your RTM server, you may relearn the probes from Device Details Windows. You can also update the stealth database: 1. Change the directory to $RTMHOME/rtm/bin. 2. On Windows platforms, execute the following commands.
a. nGeniusSQL.bat sqlscripts\ b. nGeniusSQL.bat list.out
a. ./nGeniusSQL.sh sqlscripts/ b. Edit the list.out file by removing the first two lines (header). c. ./nGeniusSQL.sh list.out 3. Restart RTM server |
CSCdx56322 | Time Triggers Data Capture does not work with Catalyst 6500 and 6000 Series NAMs. | This is a known issue. |
CSCdx56482 | RTM failed to start Data Capture for Catalyst 5000 NAM. | This is a known issue. |
CSCdx56220 | nGenius RTM does not support NIS+ for Solaris platforms. | If RTM is installed on a Solaris server with NIS+, there may be difficulties in creating an ngenius account, which will cause RTM to not install correctly. This is because the ngenius user account has to be authenticated on the NIS+ server and some NIS+ policies may not allowed such an account to be created. To work around this problem, create the ngenius user account and ngenius group on the following local machines: /etc/passwd /etc/shadow /etc/group |
CSCdx36825 | RTM does not properly learn a Catalyst 3548XL switch. | To work around this problem, when adding a Catalyst 3548XL switch, add the switch in Learn Only mode. |
CSCdx40454 | RTM indicates warnings when trying to add numerous switch types. | Since the trapDestTable is not supported on XL switches, RTM should not do SNMP SET on trapDestTable for XL switches. A warning message is displayed indicating a protocol write error when in fact, this should be considered normal for the XL switches. This message can be safely ignored. |
CSCdx50068 | Traffic Monitor does not display data in NL and AL views if a VLAN is spanned first. | To work around this problem, after you add a Catalyst 6000 switch to RTM, span a port (or ports) first. You can then remove the span session, and span VLANs. |
CSCdw23024 | RTM runs slow if accessed over a VPN network. | To work around this problem, you must add a Java Runtime parameter to your java Plug-in Control Panel. 1. Select Start>Settings>Control Panel. 2. Double-click the Java Plug-in. 3. In the Java Runtime Parameters text field enter: -Djava.rmi.server.hostname=client_addr
|
CSCdx25995 | RTM displays errors messages in the Windows Event Viewer. | These messages can be safely ignored. |
CSCdv75516 | Importing Cisco IOS switches from CiscoWorks 2000 failed. | The nGeniusciscoimport batch file proceeds without error messages even though the required dat files do not exist. To import Cisco IOS switches, use a text editor to edit the hwreport file. Replace the SysDescription string from "Cisco Internetwork Operating System" with the four numbers of the switch model you want to add. If you want to add a Catalyst 1900 switch, the string will read: |
CSCdx47037 | RTM 1.3 does not have a way to export the inventory file. | RTM cannot export the inventory file to a CSV file for import to another RTM server or a newer version of RTM. |
CSCdw05944 | RTM does not support RSPAN for Catalyst 6000 and 6500 switches. | RTM cannot make use of the RSPN feature of Catalyst 6000 and 6500 switches. |
CSCdu33990 | Cannot open multiple nGenius applets with Management Connection. | To work around this problem, if you are using Internet Explorer 5.5, go to Tools>Internet Options>General>Settings, and click the Every visit to the page radio button. If you are using Internet Explorer 6.0, there is an additional step. Go to Tools>Internet>Options> |
CSCdu62782 | nGenius Server Admin does not allow you to edit a switch type. | To change the switch type, delete the switch and add it again. |
CSCdt61007 | nGenius event viewer is not applicable for Catalyst switches. | Events sent by Catalyst switches do not contain a description field. Because the nGenius event viewer uses the description field, it cannot determine if the switch event was a rising or falling threshold. |
CSCdu88839 | Only one port can be spanned to a Catalyst 6000 and 6500 Series NAM in Cisco IOS switches. | You can only span to one port in a Catalyst 6000 and 6500 Series NAM in switches running Cisco IOS software. |
CSCdu40080 | There is no tool to recover or fix the nGenius database if it is corrupted. | If the database is corrupted you can recover the data by creating a new database and adding the old configuration data using dbunload and dbreload. 1. Navigate to the $RTMHOME/rtm/bin folder. 2. Run dbunload. This program copies your device configuration table information into the file unloadFiles located in the $RTMHOME/rtm/database directory. 3. Run dbreload. Only the configuration data is saved. All statistics data will be lost. |
CSCdx11845 | RTM cannot set different short and long term history parameters for SwitchProbe devices. | This is a known limitation. |
CSCdx14660 | Adding a switch to RTM displays an error when selecting automatic as the switch type. | Adding a switch using automatic switch type will display a "Device not recognized" error. When adding a switch, select the matching switch type. |
CSCdx15811 | RTM does not learn VLANs for a Catalyst 4006 switch with a Supervisor 3. | RTM does not support the Catalyst 4006 switch with a Supervisor 3 with this release. |
CSCdx15887 | Adding a Catalyst 6509 and 6513 switch running Cisco IOS 12.1 generates a protocol write error. | RTM does not support Cisco IOS 12.1 with this release. |
CSCdx15897 | Using different read/write community strings between the switch and the NAM does not work. | If you use different read/write community strings between the switch and the NAM, the nGenius Server will display an error message. The read/write community strings must match. |
CSCdx19043 | You cannot view total or in/out information from the short-term/long-term usage category. | This is a known limitation. |
CSCdx30822 | The New Folder button in Server>File>Table Export has no functionality. | This is a known issue. |
CSCdx30877 | Scroll bar in the Packet Analyzer>Decode window does not work. | This works as designed. You can use the arrow buttons to scroll through the window. |
CSCdx30881 | RTM initial window displays a "Server not found" error. | This occurs when you launch RTM with Internet Explorer. This message can safely be ignored. |
CSCdx36951 | After upgrading to RTM 1.4, RTM 1.3 Packet Analyzer must be removed using the Add/Remove Programs window. | This is a known limitation. |
CSCdx40502 | An error message is displayed when adding a switch with two NetFlow enabled NAMs. | RTM does not support two NetFlow enabled NAMs in the same switch. RTM can only use one NAM as a NetFlow source. |
CSCdx40518 | RTM does now allow full device table export through the GUI. | You can export the device table in xSV or HTML formal, however the file does not contain any community strings. To export the full device table: Navigate to the $RTMHOME/rtm/bin folder. Run nGeniusSQL.sh. This creates a devicelist.txt file. |
CSCdw13264 | Cannot log into nGenius due to filesystem permissions. | If the filesystem permissions for the RTM install directory are not set correctly, RTM will install successfully but you will not be able to log into the RTM server. To work around this problem, the filesystem permissions must be set to 755 (rwxr-xr-x). If this is a mounted partition, make sure the permission is set to 755 before mounting. |
CSCdt69162 | Traffic Monitor and Packet Analyzer do not show all VLANs on a switch. | VLANs that do not have at least one access switchport configured will not show up as managed elements in Traffic Monitor or Packet Analyzer. To work around this problem, either place at least one access switchport on the VLAN you want to monitor, or configure a span session for the VLAN. |
CSCdw24020 | RTM 1.3 installation will not work if IP address is provided. | If the /etc/hosts directory does not have a hostname in fully qualified domain name (FQDN) format, it will ask for an IP address. An IP address will cause the installation to fail. To work around this problem, add a FQDN hostname in /etc/hosts. If prompted for an IP address during the install, enter the hostname instead. |
CSCdv11230 | nGenius does not support multiple NICs on the same server. | To work around this problem, do the following prior to installing RTM: On UNIX platforms, edit the hosts file so that a qualified IPA is at the top of the list. This binds RTM to the first IPA on the server. On Windows NT and 2000 platforms, RTM will bind to the first LAN card shown in the network control applet. |
CSCdx07013 | RTM will not install on Win servers with Active Directory. | If you are using Active Directory, make sure the RTM database password meets the password requirements of the domain policy of Active Directory. For example, if the domain policy requires that the password must be eight characters in length, then the RTM database password must also be eight characters in length. |
CSCdw84455 | Traffic Monitor does not show application layer traffic for Catalyst 5000 NAMs. | This is caused by the Catalyst 5000 NAM bug CSCdx49381. After running for a few days, the control entries for protocolDir will disappear. To work around this problem, reboot the NAM and relearn the Catalyst 5000 switch from the nGenius server. |
CSCdv73033 | RTM 1.3 templates create incorrect RMON event and alarm indexes for Catalyst 2900XL switches. | To work around this problem, you must log into the switch and manually change the rmon alarm values. |
CSCdx05808 | nGenius only writes to the running configuration of Catalyst 3500XL switches. | If the switch is rebooted, all configurations made by nGenius will be lost. |
CSCdw29439 | RTM database import from TrafficDirector can take numerous hours. | The import status log might only show the import has started but does not show when it is completed. |
CSCdu67612 | RTM limits the characters that can be used for the database password. | A number cannot be used as the first character of the database password. The password must consist of alphanumerics only. To work around this issue, you can edit the createUser.sql file and place single quotes (') around the password. This will allow you to use other characters for the password. |
CSCdw31885 | RTM does not work across an NAT firewall. | The workaround is in Appendix B of the NetScout nGenius Real-Time Monitor 1.4 Getting Started Guide. |
CSCdw23394 | RTM Link Usage, Short Term Usage, and Long Term Usage may not match templates. | The Long Term and Short Term usage does not work with Multilayer Switching Feature Card (MSFC) interfaces. This is a known limitation. |
CSCdt30078 | RTM displays invalid login errors when server is restarted. | If the nGenius Server has been restarted but the client browser has not, attempts to log in result in errors. To work around this problem, restart the client browser, then log in. |
CSCdt34319 | RTM displays an error message if Java plug-in is not installed when using Netscape browser. | To work around this problem, you must install the Java plug-in before launching RTM. |
CSCdt36936 | Uninstalling RTM does not remove all files. | After you uninstall RTM, several directories remain under the ngenius installation directory. To work around this problem, manually remove the ngenius installation directory after running the uninstallation program. |
CSCdt36673 | Uninstalling RTM does not stop nGenius services. | If you run the uninstallation program before the nGenius services shut down, RTM is only partially removed. To work around this problem, shut down the nGenius services (from the Services Control Panel) before starting the uninstallation and follow the instructions in the NetScout nGenius Real-Time Monitor 1.4 Installation Guide. |
CSCdv24809 | RTM cannot clean up collected data. | There is no utility to reduce the size of collected data in the RTM database. By default, nGenius turns on logging for all protocols; as a result, stealth.db can grow quickly when there are many PVCs or DLCIs. |
CSCdv31663 | Installation fails on Windows systems with server (netBIOS computer) name ngenius. | On Windows NT systems, the server name and user names are assigned unique Security Identifiers (SIDs). RTM does not recognize when the server name and user names are both ngenius. To work around this problem, change the Windows system name. |
CSCdt62297 | RTM and another trap receiver application cannot coexist. | If you install RTM and another trap receiver application (such as TrafficDirector or Device Fault Manager) on the same server, you must configure each application to receive traps properly. By default, RTM listens on port 162. To change the setting so that RTM is not the primary listener application: 1. Stop the nGenius Server. 2. Open the file /nGenius_dir/bin/serverprivate.properties (where nGenius_dir is the complete path to the installed nGenius Server files). 3. Change this line: devicelistener.portlist=162,395
devicelistener.portlist=395 4. Save and close the serverprivate.properties file. 5. Restart the nGenius Server. 6. Follow the instructions in the documentation for the other trap receiver application to forward traps to port 395. |
CSCdt77889 | nGenius Server does not start if another application uses port 1099. | If you install RTM on a system where no other applications are using port 1099, RTM uses port 1099. If another application tries to bind to port 1099 while nGenius is using this port, that application will fail. However, if the nGenius Server is not running when another application binds to port 1099, that application continues working successfully while the nGenius Server cannot start. To work around this problem, change the RMI port used by RTM by manually editing the $RTMHOME/bin/serverprivate.properties and $RTMHOME/html/client.properties files. In those files, change the RMIRegistryPort=1099 to RMIRegistryPort=1100 (or the next available TCP port). |
