CDDI/FDDI Workgroup WS-C1100 Concentrator
Release Note

Caveats of Release 3.3

This section covers the caveats and known issues for Release 3.3:

• During peak times of IP Broadcast use on the FDDI ring, the response time of the Telnet session to the concentrator might be slow.
  

• When the IP address of a concentrator is changed from one class to another, the old IP Broadcast address is retained. You must explicitly set the new IP address by using the following command:
  

Console> set ipaddress

The linkUp and linkDown traps are generated by the concentrator when a physical connection to a port goes up or down. By default, this is enabled on all ports.

• Changing the subnet mask for an IP address dynamically might leave old entries in the routing table. To clear the old entries from the routing table, reset the concentrator, as in the following example:
  

Console> set ipaddress 172.20.21.201 255.255.0.0 172.20.255.255

Resolved Issues and New Features for Release 3.2

This section describes the issues that were resolved and the features that were added during this revision of the Workgroup WSC1100 Concentrator software:

1. This release supports RFC 1573. For more information, refer to the Evolution of the Interfaces Group of MIB-II.
   

2. You should update to the latest version of the Cisco-stack MIB.
   You can obtain a copy of the Cisco MIB file in two ways:
   

   • Use File Transfer Protocol (FTP) to access the cisco.com server.
     

   • Use CIO to access the cisco.com server.
     

Using FTP to ACCESS the MIB File

You can obtain the file cisco-stack.mib describing the Cisco MIB with the following procedure:

Step 1 Use FTP to access the server ftp.cisco.com.

Step 2 Log in with the username anonymous.

Step 3 Enter your e-mail name when prompted for the password.

Step 4 At the ftp> prompt change directories to /pub/MIBs/xx. Where xx is v1 for SNMPv1 MIBs, v2 for SNMPv2 MIBs, schema for SNM schema files, oid for object ID files, and traps for trap files.

Step 5 Use the get README command to display the readme file containing a list of available files.

Step 6 Use the get cisco-stack.mib.my command to obtain a copy of the MIB file.

Using CIO to Access the MIB File

You can obtain the file cisco-stack.mib describing the Cisco MIB through CIO.

For information on using CIO, refer to the "Cisco Information Online" section in this document.

1. Passwords in the configuration file allow two-level password protection. The login and enable password modes are normal and privileged, respectively.
   

2. The set unreachable <enable | disable> command was added to support the ability of the concentrator to send ICMP unreachable messages. The default is disable.
   

To enable this command use the following command:

Console> (enable) set unreachable enable
ICMP Unreachables enabled

To view the status of the ICMP unreachables, use the following command:

Console> (enable) show snmp

1. The following is a list of the new traps added to this release.
   

enterprise 1.3.6.1.4.1.9.5
1 lerAlarmOn
2 lerAlarmOff
3 chassisAlarmOn
4 chassisAlarmOff
5 linkUp
6 linkDowm

To receive traps on an SNMP management station, follow these steps:

Step 1 Configure an IP address to the concentrator using the following command:

Console> (enable) set ipaddress
Usage: set ipaddress <ip_addr> [net_mask [broadcast_addr]]
(all values given in IP dot notation: a.b.c.d)

Step 2 Use the ping utility to verify that you can reach the SNMP management station. If the SNMP management station is on a different network, set a default gateway for the concentrator using the following command:

Console> (enable) set route default < ip_addr >

Step 3 Enable the trap on the concentrator using the following command:

Console> (enable) set trap enable
SNMP authentication traps enabled

Step 4 Set the trap receiver address with the proper community string using the following command:

Console> set trap <ip_addr> <community string>
SNMP trap receiver added

SNMP trap receiver added

To view the status of the SNMP configuration, use the following command:

Console> show snmp

The following is an example of the output:

Console (enable) show snmp

Known Issue and Workaround

Once the Workgroup WS-C1100 Concentrator Flashcode Version 3.1 is installed, future network downloads will allow only Flashcode with the WS-C1100 signature to be loaded. All Version 3.1 and later versions of the Workgroup WS-C1100 Concentrator Flashcode will contain the WSC1100 signature.

To download or copy an earlier version of Flachcode, you must specifically request the no-signature option by adding the nosig argument to the download command. Following is an example:

Console> (enable) download cres c1100_10.net nosig
This command will disconnect your telnet session.
Download image c1100_10.net from host cres to flash (y/n) [n]? y
