Upgrading to New Software Releases

This section explains

Getting Software from CCO

You can download software upgrades from CCO to your PC or workstation; see the section "Cisco Connection Online,", for URLs, and note that you must register with CCO before using it. Registration instructions are provided at the site.

Within CCO, go to http://www.cisco.com/cgi-bin/getftp.pl/wg_catalyst_1800 to find the latest version of the software for the Token Ring and FDDI modules. Table 1 lists the files in that area.


Table 1: Release 2.2.1 Software Files
File Name Description

ASCII text file containing the Catalyst 1800 proprietary MIB in ASN.1 format.

CCO: t1800-readme.2-2-01.pdf
DOS: t18rnote.txt

Copies of this release note in PDF (portable document format) and ASCII text.

Download the appropriate file for each module type and the specific method you will use to move the file to your Catalyst 1800 switch (Xmodem-serial or TFTP). To perform the download by way of the serial port or TFTP, refer to the software download procedures found later in this release note.


Note If you download binary (.bin) files from CCO to a DOS system, you must change the filenames to conform to DOS file naming conventions. Use the DOS name for each file given in the table above. (t1800-tr-serial-boot.2201.bin becomes citr2201.cof.)

For example, if you download t1800-tr-serial-boot.2-1-12.bin to a DOS system, the filename may be truncated to t1800-tr.bin. Before downloading another file, rename this file citr2201.cof. (Type ren t1800-tr.bin citr2201.cof, or enter the name citr2201.cof as the DOS target filename for your download utility.) If you download another file without renaming the first file, the second file may overwrite the first one if the first eight characters of their names are the same.

Cisco recommends that you use the filenames listed in
Table 1. If you cannot do that, be sure that the string "tr" occurs in the name of every Token Ring software file, and that the string "fd" occurs in the name of every FDDI software file. This is required when you are configuring file names for TFTP download.

Using the Console to Upgrade Software

Use this procedure to load new Catalyst 1800 software from your PC or workstation to a
Catalyst 1800 switch. (See the section "Getting Software from CCO,", for instructions on downloading software from CCO to your PC or workstation.) Release TR.01.4.0 or later supports dual-board 16-port operation. Both 8-port boards must be updated with the new image for proper operation of the switch. To update a dual-board system, place the console cable on each board and perform the update procedure that follows and reboot the switch.

Use a terminal emulation program that supports the Xmodem protocol, such as PCPLUS, to download the new image from the workstation to the Catalyst 1800 switch.


Step 1   Attach the console cable (originally shipped with the switch) from the terminal emulation system to the front console port on the switch. (See the Catalyst 1800 Token Ring Switch Cable Kit Guide for more information on how to connect the console cable.)

Step 2   Use the software download command (System....Download). This places you at the monitor prompt (=>). (If unreadable bytes appear on your screen or the prompt does not appear, press Return several times so that the monitor can autobaud the serial line.) It is recommended that you set your terminal emulation program communication speed to 38,400 bps. (At that rate, a download normally takes 4 to 5 minutes.)

Step 3   At the monitor prompt (=>), type do for download. The message "Downloading" appears. The monitor is now ready to accept the Xmodem download file.

Step 4   Start the Xmodem download procedure. (In PCPLUS, do this by pressing the Page Up key, selecting the Xmodem download protocol from the menu (X), and typing in the download image name, for example citr2201.cof for the Token Ring card.)

Step 5   Once the image has been downloaded, a "Download Complete" message and the monitor prompt are displayed.

Step 6   Type go. Messages are displayed to indicate that the image is being stored in Flash for use by subsequent reboots.

Step 7   To start the new, downloaded image, switch the system off and then on again.

The switch starts running the new code when you power it on. The Password menu appears after boot-up.

Caution If you have upgraded the software version to TRX/FDU.2.2.1, but want to revert back to an earlier version, you should save your configuration file to a TFTP server using the configure tftp upload start changes y command. Then you must reset and re-key the database manually.

Note When you perform a software download over an asynchronous modem, configure the modem for Auto-answer and Disabled result codes. To do so, execute the following standard modem commands:
ATS0 Enables auto-answer
ATQ1 Disables result codes

Using TFTP to Upgrade Software

You can use TFTP to load new Catalyst 1800 software from your PC or workstation to a
Catalyst 1800 switch. (See the section "Getting Software from CCO,", for instructions on downloading software to your workstation.) TFTP upgrades can be performed while the switch is in operation. Switching continues with only a 5-second pause in operation while the image is being stored in the on-board Flash memory. To configure and initiate a TFTP download, refer to the TFTP menu selection (Configure...TFTP) on the console. Use the files citr2201.img and cifd2201.img to upgrade using TFTP.

SNMP Implementation Notes

A proprietary MIB is now supported. For the latest version of the MIB, visit Cisco Connection Online (CCO), or contact Cisco Systems customer support at 1-800-553-2447. CCO and customer support are available 24 hours a day, 7 days a week.

The following notes describe the implementation of the standard MIBs in the switch:


Note If you are implementing a Network Management Client for this switch or need a more detailed view of the MIB implementation, request the Network Management FAQ (Frequently Asked Questions listing) from customer support.

Caveats: Known Restrictions and Limitations for TRX.2.2.1 and FDU.2.2.1

General Caveats

  Suppose the Catalyst 1800 has port 5 (for example) as ring 0x01. Even if the port is inactive/disconnected, traffic from PC1 will not be forwarded to ring 0x03 where PC2 is.
  This operation is expected in the Catalyst 1800. The PC1->PC2 traffic is being dropped by the Catalyst 1800's loop-detection algorithm. When the Catalyst 1800 detects a ring number in the RIF that is different from the ring number of the port the frame was received on, yet is a valid ring number in the configuration, it assumes the frame already traversed this switch.
  To work around the issue, ensure the VLAN ring number configuration is valid by removing duplicate ring numbers in the network, or attach the port that has the duplicate ring number to its associated network. (DDTs no. CSCdj08120)

Console Interface Caveats

RMON/Traffic Director Caveats

This version of the software supports RMON RFC 1757 (RMON base) and RFC 1513 (Token Ring specific). Traffic Director 3.3 can access the Catalyst 1800 using its standard menu interface; however, a few exceptions are noted in this section.

Traffic Director Requires a Software Patch

RMON requires a patch to Traffic Director 3.3. The patch is available through CCO; contact Cisco at 1-800-553-2447 for help in downloading the patch. (DDTS no. CSCdi74642)

Enabling Statistics/Ring Information

RMON groups are off by default. Each group on each port can be separately enabled/disabled. Follow these steps to enable or disable RMON groups in the Catalyst 1800 switch:


Step 1   Add a new agent type, specifying the interface (physical port) and IP address of the switch.

Step 2   Create a domain for that agent by selecting Domain Manager from the main screen.

Step 3   From Domain Manager, you need to install the new agent. Select Install to enter the Install Domain.

Step 4   In the Install Domain, select the agent, then select RMON from the Domain List.

Step 5   Select Host from the Enable Groups section if you would like host information (time creation, per host statistics, and so on).

Step 6   Select OK in the Install Domain, and Traffic Director automatically creates the RMON groups in the switch.

Enabling Ring Station Groups from Traffic Director

To enable the Ring Station groups of RFC 1513 from Traffic Director, enter the Traffic Director shell. In the shell, execute the following command for each agent that you would like to acquire ring information for:

dvtrstn add agent
  In this command, agent is the agent you are adding, for example, P3-CAT1800.

Once you execute the command, you can exit the shell window.


Note From CiscoView for the Catalyst 1800, if you want to obtain ring-station information immediately, disable and then re-enable the associated interface (physical port) the first time you configure a ring-station group.

Execute these commands the first time you create a new agent or enable a ring-station group. The switch stores this configuration information for subsequent reboot(s) of the switch.

General RMON Caveats

User Documentation Caveats

Current documentation for the Catalyst 1800 switch is shipped in the box with the system.

The following changes to the user interface are not yet reflected in the Catalyst 1800 Token Ring Switch User Guide:

  Before changes to these parameters can take effect, you must reboot the switch using the System Reboot command.

Modifications

This section describes recent changes to the Catalyst 1800 hardware and software.

Hardware Modification

Under certain conditions, the FDDI console gets locked in a state where it streams characters continuously to the console port. The problem occurs only when the console port is connected and you enter a command. When the problem occurs, the switch continues to operate at slightly reduced performance, but it does not respond to console commands. This has occurred only in the manufacturing environment; it has not been reported in the field. The problem has been corrected with new PALs.

Revision numbers for boards in which the problem has been corrected are listed in Table 2. You can check a board's hardware revision information at the console by entering con sys display to display the System Information menu. (DDTs no. CSCdi90452)

Modifications to TRX.2.2.1 and FDU.2.2.1

The TRX.2.2.1/FDU.2.2.1 release includes the following changes from the previous release:

  fddimibSMTStationId: SNMP Object Value is not in canonical form.
  fddimibSMTTimeStamp: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibSMTTransitionTimeStamp: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibMACUpstreamNbr: SNMP Object Value is not in canonical form.
  fddimibMACDownstreamNbr: SNMP Object Value is not in canonical form.
  fddimibMACOldUpstreamNbr: SNMP Object Value is not in canonical form.
  fddimibMACOldDownstreamNbr: SNMP Object Value is not in canonical form.
  fddiMACSMTAddress: SNMP Object Value is not in canonical form.
  fddimibMACTReq: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibMACNegT: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibMACTMax: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibMACTvxValue: SNMP Object Value does not correspond to the SMT Parameter Value.
  fddimibPATHConfigTokenOrder: SNMP Object Value is out of range.
  fddimibPATHConfigResourceType: SNMP Object Value is out of range.
  fddimibPATHConfigCurrentPath: SNMP Object Value is out of range.
  fddimibPORTHardwarePresent: SNMP Object Value does not correspond to the SMT Parameter Value. (DDTs no. CSCdi88196)
  From a MIB perspective, ideally with two boards, a table of console-related objects would be necessary to help in configuring each console separately. Currently, in the private MIB for the Catalyst 1800 device, the console group contains scalar variables for the console port; this makes it impossible to configure both the ports. (DDTs no. CSCdi86235)
TFTP download Completed Success fullyDetected.
  The print statement displays proper download messages after the TFTP download. (DDTS no. CSCdj06083)
   no entries found in the netbios name database
  You can delete the entire database with a single command. If you repeat the command, the message is displayed. (DDTS no. CSCdi83178)

Modifications to TRX. 2.1.12 and FDU.2.1.12

The TRX.2.1.12/FDU.2.1.12 release includes the following changes from the previous release:

Modifications to TRX.2.1.11 and FDU.2.1.11

The TRX.2.1.11/FDU.2.1.11 release includes the following changes from the previous release:

Modifications to TRX.2.1.10 and FDU.2.1.10

The TRX.2.1.10/FDU2.1.10 release included the following changes from the previous release:
