Error Possible Cause Possible Solution

File not found.

tftp_req_file failed, val=-1

The command syntax is incorrect or the file cannot be found on the TFTP1 server.

Enter download help for syntax information and retype the command. Make sure the filename is correct and that the file is located on the TFTP server.

No more processes.

tftp_reqfile failed, val=-1

The Catalyst 1200 series switch has no processes available
(maximum = 16).

Terminate unnecessary tasks, such as Telnet sessions or pings. Then retry the download.

TFTP session in progress. Try again later.

There is already a download in progress.

Retry the download when the current download process is complete.

<LCP> not enough memory, use fragmented buffers.

<LCP> use fragmented buffers for download.

The Catalyst 1200 series switch did not find an unfragmented memory chunk, as required for the download process. The Catalyst 1200 series switch allocates the fragmented buffers to a chained list and continues.

None required.

<LCP> RMON task killed.2

If after allocating the fragmented buffer to a chained list, the Catalyst 1200 series switch still does not have enough memory, it terminates the RMON3 task.

None required.

<LCP> Router RIP killed.2

<LCP> SNMPDM killed.2

<LCP> THREAD killed.2

If after allocating the fragmented buffer to a chained list and terminating the RMON task, the Catalyst 1200 series switch still does not have enough memory, it terminates the RIP, SNMPDM, and THREAD tasks.

None required.

No Response from host.

tftp_req_file_failed, val=-1

The Catalyst 1200 series switch attempted to connect to the TFTP server, but the connection failed.

Check the physical connectivity to the server. Then check that the IP address or alias for the TFTP server is correct and retry the download.

Can't allocate process state buffer.

The Catalyst 1200 series switch does not have enough memory to start the TFTP process.

Other applications might be using too much memory. Retry the download when there is less traffic or terminate the unnecessary Telnet sessions or pings.

TFTP failed. Too many retries.

The Catalyst 1200 series switch was disconnected from the TFTP server while downloading the image file.

Check that the network is operational, then retry the download.

Downloaded NMP code length is bad.

tftp_req_file failed, val=-1

The image was corrupted because of a TFTP problem.

Retry the download.

Downloaded NMP code checksum failed.

tftp_req_file failed, val=-1

The image was corrupted because of a TFTP problem.

Retry the download.

The NMP flash was damaged, must first download a valid image.

You entered Ctrl-C while the Catalyst 1200 series switch was clearing or erasing Flash memory.

Retry the download of the same Flash image. If this error occurs again, contact Cisco's Technical Assistance Center.

1TFTP = Trivial File Transfer Protocol.
2After the download successfully completes, the Catalyst 1200 series switch automatically reboots and restarts terminated processes.
3RMON = Remote Monitoring

Backing Up RMON Domains

RMON domains can be archived so that if the Catalyst 1200 series switch reboots, the RMON domains can be retrieved. To save the installed RMON domains, follow these steps:

Step 1 After installing the RMON domains from a NetScout Manager on a server, change to the bin directory under the directory where NetScout Manager is installed. For example, if the NetScout Manager is installed in/usr/nsman, then change to the /usr/nsman/bin directory.

Note If the agent-list file in the /usr/nshome/usr directory already exists, remove this file before proceeding.

Step 2 Save the list of installed domains of an agent into a new file (agent-list) in the directory where the startup file is saved, for example, in /user/nshome/usr. To save the domains on a UNIX server, type the following:

    dvlist agent > ../usr/agent-list

Step 3 Change to the /usr/nshome/usr directory.

Step 4 Copy the startup file (startup) into a new file (agent-startup).

Step 5 Open the new file (agent-startup). Replace the dvinst.cfg parameter in both places with the name of the new agent list file (agent-list) created in Step 2. Save and exit this file.

Step 6 Enter the NetScout Manager application. In the Start Up File field for the agent that needs to be saved, enter the name of the new agent startup file (agent-startup).

For each agent that uses this protocol and these groups in their domains, enter the name of the new agent startup file in the corresponding Start Up File field.

Step 7 Repeat Steps 4 through 6 for each agent that has different protocols and groups in its domain.

Software Release 4.30 and 4.32 Software Modifications

This section describes issues resolved in the Catalyst 1200 series switch Network Management Processor (NMP) and Data Movement Processor (DMP) software release NMP 4.30 and 4.32.

NMP 4.30 and 4.32

The following issues have been resolved in Catalyst 1200 series switch NMP software releases 4.30 and 4.32:

If you Telnet to the switch on TCP port 7161 and enter a carriage return, the Network Management Processor hangs. The workaround is to power cycle or manually reset the switch. This problem is fixed in software release 4.30 and 4.32. (CSCdj71684)

Software Release 4.30 and 4.32 Caveats

There are no new caveats and workarounds for software release 4.30 and 4.32.

This problem has been fixed in software release 4.26. (CSCdi71550)

Software Release 4.26 Caveats

This section describes possible, unexpected behavior by software release 4.26. The caveats listed here describe only serious problems.

Workaround:
This problem shows up if the Catalyst 1200 series switch receives an IGMP packet with an unknown IGMP_TYPE (or one that Catalyst 1200 series switch does not handle). Currently, the following IGMP_TYPEs are handled:
    IGMP_PIM
    IGMP_HOST_MEMBERSHIP_QUERY/IGMP_HOST_MEMBERSHIP_QUERY_VER2
    IGMP_HOST_MEMBERSHIP_REPORT/IGMP_HOST_MEMBERSHIP_REPORT_VER2
    IGMP_DVMRP
Workaround:
Use Catalyst 1200 series switch software release 4.1, which supports inter-VLAN bridging for AppleTalk.
Workaround:
Use default pathcost for Ethernet interfaces.
Workaround:
Use the download serial command with the Kermit application, as mentioned in the Catalyst 1200 Series Switch User Guide.
Workaround:
Set the CAM aging time value for all VLANs to zero. Clear the CAM table to learn new entries.
Workaround:
Exit from the SNMP application before resetting the Catalyst 1200 series switch.

Software Release 4.21 Software Modifications

This section describes issues resolved in the Catalyst 1200 series switch NMP and DMP software release NMP 4.21.

NMP 4.21

The following issues have been resolved in the Catalyst 1200 series switch NMP software release 4.21:

DMP 4.21

The following issues have been resolved in the Catalyst 1200 series switch DMP software release 4.21:

New Features in Software Release 4.1

DMP software release 4.1 is an upgrade to the previously released DMP 3.27.

NMP software release 4.1 is an upgrade to the previously released NMP 3.27.

The following features have been added:

Software Release 4.1 Caveats

This section describes possible, unexpected behavior by software release 4.1. The caveats listed here describe only serious problems.

Workaround:
Disable the modem using the set modem disable command.
Refer to Figure 1 and the following example:
Catalyst 1200 series switch A has ports 1 and 4 in bridge VLAN 1 and ports 5 and 6 in bridge VLAN 2. This same switch has ports 1 and 4 in IP VLAN 10 and ports 5 and 6 in IP VLAN 20. This switch is connected in a looped configuration to Catalyst 1200 series switch B.
Catalyst 1200 series switch B has ports 1 and 5 in bridge VLAN 1 and ports 7 and 8 in bridge VLAN 2. This same switch has ports 1 and 5 in IP VLAN 30 and ports 7 and 8 in IP VLAN 40.

Figure 1: Example of Catalyst 1200 Series Switches in a Looped Configuration


Workaround:
For IP connectivity, configure a default route on the Catalyst 1200 series switch instead of allowing it to learn Routing Information Protocols (RIPs).
Workaround:
Clear the Address Resolution Protocol (ARP) entry for the Catalyst 1200 series switch's IP address from the originating IP station's ARP table, or clear the ARP table on the Catalyst 1200 series switch you are trying to reach.
Workaround:
Do not abort a serial download. Let the serial download complete. If you do abort a serial download, reset the switch and reinitiate the serial download.
Workaround:
When you enter new route groups using the Brouter Table menu form in Workgroup Director, make sure to correctly enter all the IP information, including the IP address, subnet mask, and broadcast address. Click the SET button to add the new route group configuration.
Workaround:
Set up default routes in the switch's routing table and limit the broadcast frames that the switch receives by using the set filter broadcast command throttling mechanism.
Workaround:
Do not abort a serial download. Let the serial download complete. If you do abort a serial download, reset the switch and reinitiate the serial download.
Workaround:
If you remove an IP network from your routing group, delete the corresponding default route using the clear route default command.
However, entries can still be added manually. The Catalyst 1200 series switch discards the oldest dynamic entry and adds the new entry.

Fixed Caveats in Software Release 4.1

The following caveats were experienced in previous Catalyst 1200 series switch releases and have been corrected in software release 4.1.

A fix has been provided so that the switch automatically detects whether an interface is UP or DOWN. It advertises only interface routes that are UP. The switch does not advertise interface routes that are DOWN, disabled, or disconnected.
Also, this situation might have caused the nonroot bridge to send duplicate ping responses on a blocked spanning-tree port. The switch could not respond to pings on a blocked spanning-tree port.
The situations described above no longer occur.
The console no longer gets locked.
Reassembly of large packets has been disabled; therefore, the Catalyst 1200 series switch now drops any large packets.
The Catalyst 1200 series switch automatically detects the correct status of the port.

Software Release 4.1 NetScout RMON Caveats

The following caveats to the NetScout RMON have been identified and workarounds are provided:

All submenu actions items must be completed before other Main menu items may be activated.
Workaround:
Reduce the frozen screen(s) to icons to find the active submenu screen hidden behind. The active submenu screen must be closed to allow another Main menu selection.
The Catalyst 1200 series switch will attempt to install all possible resources using the available memory. If the switch is not successful installing all of the enabled groups for the chosen domain, it will install as many as possible and display the following error messages:
    no resources...
    could not install
Workaround:
Use the Domain Management menu to confirm completion of the RMON configuration or use the Domain Manager submenu from the Main menu screen to install logical agents.
This error message does not indicate the Catalyst 1200 series switch is down. This error message may be caused by one or more of the following conditions:
Workaround:
To verify the Catalyst 1200 series switch state, ping the switch or refer to the console window to determine the problem.
To specify segments, make a drawing of all nodes including bridges, routers, and gateways.
Workaround:
Correct the mistakes by editing the configuration file associated with that agent and then reinstalling the file.
