These release notes describe the features, notes, caveats, and caveat corrections for CDDI/FDDI Workgroup WS-C1100 Concentrator Release 3.6. Refer to the CDDI/FDDI Workgroup WS-C1100 User Guide for detailed information about the CDDI/FDDI Workgroup WS-C1100 Concentrator.
Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.
This document is divided into the following sections:
The following sections describe the caveats and corrected caveats in Release 3.6.
This section describes caveats that have been corrected in the 3.6 release.
- It is possible to set an invalid date, such as February 29th, on a year that is not a leap year. This caveat is fixed in this release of the concentrator software. [CSCdj20518]
For reference, see also CSCdj20509 and CSCdj20543.
- The concentrators are vulnerable to the LAND.C Denial of Service Attack program. This caveat is fixed in this release of the concentrator software.[CSCdj62723]
This section describes the caveats for Release 3.6.
- 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> (enable) set ipaddress new_ipaddress
- When dynamically changing the subnet mask for an IP address, old entries might exist in the routing table. To clear the old entries from the routing table, reset the concentrator, identifying the old IP addresses, as follows:
Console> (enable) set ipaddress old_ipaddress old_ipaddress
The following sections describe the features, caveats, and corrected caveats in Release 3.5.
The following enhancement has been added to Release 3.5:
The set ringmap [enable | disable] enables or disables the WS-C1100 ring-mapping feature and saves the state to NVRAM. The default is enable.
To enable ring-mapping, enter the following command:
Console> (enable) set ringmap enable
Ring mapping enabled
To disable ring-mapping, enter the following command:
Console> (enable) set ringmap disable
Ring mapping disabled
To verify the ring map status, use the show ringmap command.
The following caveats are resolved in Release 3.5:
- When in a ring with over 200 stations, the concentrator no longer responds slowly to Telnet or SNMP requests or pings. [CSCdi50341]
- When the concentrator gets IPX/VINES broadcast frames, it no longer increments the unknown protocol errors counter and does not distort the SNMP reports that are received. [CSCdi62339]
- When the concentrator receives an all-zero broadcast (0.0.0.0) frame, it no longer responds erroneously with the following message:
tftp error: access denied. [CSCdi66808]
This section describes possibly unexpected behavior by Release 3.5.
- During peaks of IP broadcast use on the FDDI ring, the Telnet session response time to the concentrator might be slow. [CSCdi38842]
- When a standby PHY-A port transitions up and down, a dual-homed concentrator sometimes sends SNMP trap messages. [CSCdi66807]
- As a workaround, disable the trap by using the following command:
Console> (enable) set port trap 1 disable
- 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> (enable) set ipaddress new_ipaddress
- When dynamically changing the subnet mask for an IP address, old entries might exist in the routing table. To clear the old entries from the routing table, reset the concentrator, identifying the old IP addresses, as follows:
Console> (enable) set ipaddress old_ipaddress old_ipaddress
The following sections describe caveats and caveat corrections for Release 3.4.
The following caveats have been resolved in Release 3.4:
- The concentrator calculates the traffic percentage by counting the number of nonidle 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 percentage was sometimes incorrect. [CSCdi39662]
- The exception handler stores register information in NVRAM and resets the concentrator when a software exception occurs. The register information can be retrieved with the show log command. In previous releases, the exception handlers did not work correctly.
The following caveats describe possibly unexpected behavior by Release 3.4:
- When in a ring with over 200 stations, the concentrator responds slowly to Telnet or SNMP requests or pings. [CSCdi50341]
- When the concentrator gets IPX/VINES broadcast frames, it increments the unknown protocol errors counter, which distorts the SNMP reports that are received. [CSCdi62339]
- When the concentrator receives an all-zero broadcast (0.0.0.0) frame, it responds erroneously with the following message:
tftp error: access denied. [CSCdi66808]
- 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> (enable) set ipaddress new_ipaddress
- When dynamically changing the subnet mask for an IP address, old entries might exist in the routing table. To clear the old entries from the routing table, reset the concentrator, identifying the old IP addresses, as follows:
Console> set ipaddress old_ipaddress old_ipaddress
The following sections describe features, caveats, and caveat corrections for Release 3.3.
The following enhancements have been added to Release 3.3:
- The set trap enable command changes the default from disabled to enabled for all traps.
- The following link states are supported:
- Up state--LED is green.
- Dormant or standby state--LED is orange.
- Down state--LED is off.
- The dormant state occurs during the following 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 transitions from a down state to an up state.
- When a port transitions from a down state to a dormant or a standby state.
- The concentrator generates a linkDown trap under the following conditions:
- When a port transitions from an up state to a down state.
- When a port transitions from a dormant or a standby state to a down state.
Note A trap is not generated if a port transitions from a dormant or standby state to an up state or vice versa.
The following caveats have been resolved in Release 3.3:
- 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. The memory buffers are now released when the Telnet session is closed.
- When a physical connection to a port transitions up or down, the concentrator generates the linkUp and linkDown traps. 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
Console> (enable)
Console> (enable) set porttrap 2/1 disable
Port 2/1 up/down trap disabled.
Console> (enable)
This section describes possibly unexpected behavior by Release 3.3:
- During peaks of IP Broadcast use on the FDDI ring, the response time of the Telnet session to the concentrator might be slow. [CSCdi38842]
- When the concentrator calculates the traffic percentage, the percentage is sometimes incorrect. [CSCdi39662]
- When the concentrator gets IPX/VINES broadcast frames, it increments the unknown protocol errors counter, which distorts the SNMP reports that are received. [CSCdi62339]
- When a software exception occurs, the concentrator does not reset, and the exception handler does not store register information in NVRAM.
- When dynamically changing the subnet mask for an IP address, old entries might exist in the routing table. To clear the old entries from the routing table, reset the concentrator, identifying the old IP addresses as follows:
Console> (enable) set ipaddress old_ipaddress old_ipaddress
- 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 new_ipaddress
The following sections describe new features, important information, and caveats for Release 3.2.
The following enhancements have been added to Release 3.2:
- The login and enable passwords in the concentrator provide two levels of password protection: normal and privileged.
- The set unreachable [enable | disable] command enables or disables the concentrator so that it sends ICMP unreachable messages. The default is disable.
- To enable the concentrator, 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 new traps have been 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 a SNMP management station, follow these steps:
Step 1 Use the following command to configure an IP address to the concentrator:
Console> (enable) set ipaddress
Usage: set ipaddress [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 Use the following command to enable the trap on the concentrator:
Console> (enable) set trap enable
SNMP authentication traps enabled
Step 4 Use the following command to set the trap receiver address with the proper community string:
Console> set trap 172.20.21.201 public
SNMP trap receiver added
Step 5 Use the following command to view the status of the SNMP configuration:
The following is an example of the show snmp output:
Console (enable) show snmp

- show Phy
Release 3.2 supports RFC 1572. For more information, refer to the Evolution of the Interfaces Group of MIB-II.
The latest version of the CISCO-STACK-MIB.my file can be obtained from the Cisco Systems FTP site. Refer to the "Using FTP to Obtain the MIB File" section.
You can also obtain the CISCO-STACK-MIB.my file from Cisco Connection Online (CCO). Refer to the "Cisco Connection Online" section later in this document for information about using CCO.
You can obtain the CISCO-STACK-MIB.my file that describes the Cisco MIB by following these steps:
Step 1 Use FTP to access the ftp.cisco.com server.
Step 2 Use the anonymous username to log into the server.
Step 3 Enter your e-mail name when prompted for the password.
Step 4 At the ftp> prompt, change directories to /pub/mibs/.
Step 5 Change directories to one of the following:
- v1 for SNMPv1.
- v2 for SNMPv2.
- schema for SNM schema files.
- oid for object files.
- traps for trap files.
Step 6 Use the get README command to display the file that has the list of available files.
Step 7 Use the get CISCO-STACK-MIB.my command to obtain a copy of the MIB file.
The following caveats describe possibly unexpected behavior by Release 3.2:
- When the concentrator calculates the traffic percentage, the percentage is sometimes incorrect. [CSCdi39662]
- When a Telnet session is opened and closed to the concentrator, some of the numbered buffers are not released. This causes an exception when the system runs out of resources.
- When a physical connection to a port transitions up or down, the concentrator does not generate the linkUp and linkDown traps.
The following sections describe new features and important Flashcode information for Release 3.1.
The following enhancements have been added to Release 3.1:

After 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. Version 3.1 and later versions of the Workgroup WS-C1100 Concentrator Flashcode will contain the WS-C1100 signature.
To download or copy an earlier Flashcode version, 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 c1100_10.net
This command will disconnect your telnet session.
