Introduction

This release note describes new features in and modifications to the CDDI/FDDI Workgroup WSC1400 Concentrator. Refer to the CDDI/FDDI Workgroup WSC1400 Concentrator User Guide for detailed information about the CDDI/FDDI Workgroup WSC1400 Concentrator.

Product Overview

The CDDI/FDDI Workgroup WSC1400 Concentrator is a member of a family of concentrators that provide Copper Distributed Data Interface/multilevel transmission (CDDI/MLT3) and single and multimode Fiber Distributed Data Interface (FDDI) connectivity. This concentrator combines the best features of compact, workgroup-style concentrators with the flexibility of chassisstyle concentrators. Refer to the chapter "Product Overview" in the CDDI/FDDI Workgroup WSC1400 Concentrator User Guide for further explanation of product features and functions. This document is available on the Cisco Connection Documentation, Enterprise Series CD, or in print.

Resolved Issues and New Features for Release 1.5

This section describes the issues that were resolved and the features that were added during this release of the Workgroup WSC1400 Concentrator software:

This release supports a timeout feature that is configured from the console. It lets you change the time interval until the system disconnects an idle session after a period of non-activity. Use the following command:

Console>         set logout <timeout>

Where


<timeout>

is the number of minutes, from 0 to 10,000, until the system disconnects an idle session. The default is 20 minutes, and 0 disables the feature.

Traffic % is calculated by counting the number of non-idle symbols received during a specific time interval. SMT and LLC frames and tokens are included as traffic in the calculation. In previous releases, the traffic % was sometimes incorrect.
If a software exception occurs, the exception handler stores valuable register information in NVRAM and resets the concentrator. The register information can be retrieved with the
show log command. In previous releases, the exception handlers did not work correctly.

Caveats of Release 1.5

This section covers the caveats and known issues for Release 1.5:

The system can respond slowly to Telnet and SNMP requests and pings in certain environments, such as a ring with over 200 stations or a ring with large amounts of broadcast traffic.

Resolved Issues for Release 1.4

The following issues were resolved for Release 1.4

In the previous release, when a Telnet session was opened and closed to the concentrator, some of the numbered buffers were not released. This caused an exception when the system ran out of resources. As of this release, the memory buffers are released when the Telnet session is closed.
The default for all traps is disabled. To change the default of all the traps, use the following command:

Console> (enable)         set trap enable

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.

To change the default for the linkUp or linkDown trap for a specific port, use the following command:

Console> (enable)         set porttrap
Usage: set porttrap <mod_num/port_num> <enable|disable>
Console> (enable) 
Console> (enable) set porttrap 2/1 disable
Port 2/1 up/down trap disabled.
Console> (enable)

This release supports the following three link states:

UP state LED is Green.
DORMANT or STANDBY state LED is Orange.
DOWN state LED is OFF.

The DORMANT state can be reached during the following two conditions:

When you are dual-homing the concentrator or when you are dual-homing an end station.

When there is a bad FDDI or CDDI cable connected to a port or the cable is not plugged in completely.

The concentrator generates a linkUp trap under the following conditions:

When a port goes from a DOWN state to UP state.
When a port goes from a DOWN state to DORMANT or STANDBY state.

The concentrator generates a linkDown trap under the following conditions:

When a port goes from an UP state to a DOWN state.
When a port goes from a DORMANT or STANDBY state to a DOWN state.

Note No trap is generated if a port goes from a DORMANT or STANDBY state to an UP state or vice versa.

Caveats of Release 1.4

This section covers the caveats and known issues for Release 1.4.

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. The following is an example:

Console> set ipaddress 172.20.21.201 255.255.0.0 172.20.255.255

New Features for Release 1.3

The numbered list in this section describes the issues that have been resolved and the features that have been added during this revision of the Workgroup WSC1400 Concentrator software:

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

Passwords in the concentrator offer two levels of password protection. The login and enable password modes are normal and privileged, respectively.
The set unreachable <enable | disable> command was added to enable or disable 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

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 moduleUp
4 moduleDown
5 chassisAlarmOn
6 chassisAlarmOff
7 linkUp
8 linkDown

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 172.20.21.201 public
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

Resolved Issues and New Features for Release 1.2

This section describes the issues that were resolved and the new features that were added in the Workgroup WSC1400 Concentrator Release 1.2 software:

After the Workgroup WSC1400 Concentrator Flashcode Version 1.2 is installed, future network downloads will allow only Flashcode with the WSC1400 signature to be loaded. All Version 1.2 and later versions of the Workgroup WS-C1400 Concentrator Flashcode will contain the WSC1400 signature.
To download or copy Flashcode Version 1.1, you must specifically request the no-signature option by adding the nosig argument to the download command. Following is an example of a download attempt without using the nosig argument:

Console> (enable)         download 198.133.219.40 c1400_11.net
This command will disconnect your telnet session.
Download image c1400_11.net from host 198.133.219.40 to flash (y/n) [n]? y
\
Done.  Finished Network Download.  (453636 bytes)
ERROR: Downloaded code signature incorrect

Following is an example of a successful download using the nosig argument:

Console> (enable)         download 198.133.219.40 c1400_11.net nosig
This command will disconnect your telnet session.
Download image c1400_11.net from host 198.133.219.40 to flash (y/n) [n]? y
\
Done. Finished Network Download. (453636 bytes)
Initializing flash...Erasing Flash...Done

Base....Code....Length....Time....Done
Disconnected from FDDI ring.
Connection closed by foreign host.

The set tlmin command has been added to set the time required for PHY hardware to transmit a given line state before advancing to the next physical connection management (PCM) state at the station management (SMT) level. The <mod_num> is 1 or 2, and the <port_num> is 1 through 16, depending on the card. The <hexvalue> is between 0 and 0xffff. The tl_min setting is stored in the TL_MIN register (also known as the LS_MAX register) as part of the SMT management information base (MIB) structure in nonvolatile memory and is used for initializing the PHY hardware setting each time the concentrator is rebooted.

Console> (enable) set tlmin ?        
Usage: set tlmin <mod_num/port_num> <hexvalue>
       (hexvalue is in 2's complement)
Console> (enable) set tlmin 2/5 fdfd
Port 2/5 tlmin set to 0xfdfd.
Console> (enable)
