2.2(3) Version Software Release Note
Catalyst 3000 Series

The 2.2 software releases support the existing Catalyst 3000 switch family (including the Catalyst 3000, Catalyst 3100 and Catalyst 3200) and CPW1601. The 2.2 software release introduces the following features:

  • Cisco Group Management Protocol (CGMP)

    • to provide enhanced multicast management

  • Dynamic Inter-Switch Link Protocol (DISL)

    • to enhance plug and play connectivity of ISL capable ports

  • Enhanced broadcast packet handling

  • Monitoring of ATM Services (LECS, LES, BUS) via SNMP

    • these MIBs can be read from but not written to

  • Deterministic box identification in back to back (dual) Stack configurations

  • Improved system performance when creating VLANs or when moving ports between VLANs

  • Support for SNMP v2C including get-bulk transfers with transfer sizes up to 8KB

    • refer to RFC1901 for more details.

For detailed information about configuring CGMP and DISL Protocols, refer to the 2.2(1) Configuration Note. For detailed information about configuring other features on a Catalyst 3000 series switch, refer to the Installation and Configuration Guide.

Critical 2.2(2) Software Upgrading Instructions

Caution As with other 2.0 and above releases, if you are upgrading a pre 2.0 system, you MUST upgrade the bootcode first. If you do not, the system will not boot when restarted.

See the section "Downloading the 2.0 (or above) Image to a Pre 2.0 system" in the 2.0(1), 2.0(2), 2.0(3), 2.1(1) or 2.1(2) Release Notes for complete details.

Firmware and Memory Requirements for the 2.2 Releases

  • ATM Firmware revision v16 is also released with the 2.2(3) release. This ATM firmware version contains a fix for 1 anomaly (CSCdj38470). The new firmware is fully compatible with existing main images.

  • The 2.2 releases require 8MB of DRAM. For existing 4MB boxes, an upgrade kit (WS-X3428) is available.

System Limitations

  • All systems still have the same hardware limitation of no more than 4 trunk ports per box (ISL and/or ATM). ATM ports are always considered to be trunk ports. This limit is per box, not per Stack (up to 32 trunk ports can be supported in an 8 box Stack).

  • No more than 2 ATM ports can be installed per box.

  • As with all post 2.0 releases, Boot Code version 2.0 must be used for the system to boot correctly.

Configuration Notes

  • When upgrading existing systems, ISL-capable ports previously configured as Static are set to DISL state Auto, and ISL-capable ports previously configured as Trunk are set to DISL state Desirable.

  • ATM firmware version 14 and above is required to run CGMP over ATM trunks. Both v14 and v16 of the ATM firmware is backward compatible with all existing ATM releases on the Catalyst 3000 family (i.e. 1.3, 2.0(x), 2.1(x)).

  • When using the Port Statistics Screen (from the Reset Statistics menu) please observe the following caution:

Caution Clearing a port's statistics resets all of the counters for this port, both those displayed on the console and those reported via SNMP. If you are using port statistics data for important applications you should exercise extreme caution in choosing to reset a port's statistics, since all applications dependent on such statistics will be affected.

Feature Notes

  • Enhanced broadcast handling is provided by not forwarding broadcast packets to the CPU on any VLAN which has IP disabled. This allows the user to enable IP on only management VLANs and not have the CPU see broadcasts on other VLANs.

This is provided for ethernet ports in the 2.2(1) release; it is extended to ATM ports in the 2.2(3) release. ATM v16 firmware is required for this feature.
  • Reliable box identification in back to back (dual) Stacks is provided to ensure that stacks reliably reform with the boxes assuming the same box number each time. This is provided by saving the box number of each box in non-volatile memory and using that value when the stack is reforming. The earlier method of determining box numbers is still used if there are no valid box numbers saved or the boxes have conflicting information due to a box being replaced.

  • The ability to access the debug menu from a telnet session has been added in the 2.2(3) release. This removes the need for a directly connected console when debug access is required. When telneting to a Stack, the debug menu is available only for the IP controller box (usually the lowest numbered box in a Stack). Direct console connection is still required if debug access is needed for a box other than the IP controller box.

NMS Notes

  • A CiscoView package (version 1.4) for the Catalyst 3000 series, which provides full support for the 2.2 releases, will be available on CCO. This package will be incorporated into the CWSI 2.0 release.

Known Anomalies

The following are known conditions as of this version of the software release.

CGMP Limitations Over ATM (CSCdj04492)

Multicast sources arriving at the Catalyst 3000 series via an ATM port cannot have the list of destination ports controlled by CGMP. This is a limitation of the ATM subsystem and is not planned to be fixed in any future release.

This limitation is described in detail in the CGMP section of the 2.2(1) Configuration Note.

CGMP and Filter Table Entry Conflict (CSCdj15673)

It is not possible to run CGMP and have Address Filtering in use at the same time. CGMP will override filter table entries.

Invalid Warning Message Generated when Configuring Default ATM LANE LECS (CSCdj06271)

When configuring a new system to be LECS and LES+BUS, if an ATM address for the default ELAN is added before the system is rebooted, a warning message appears. The system behavior is not affected; the default ELAN comes up correctly. A workaround for avoiding the warning message is to reboot the system after configuring the system as LECS, LES+BUS and before assigning ATM addresses.

SNMP Sets Are Not Supported for ATM LANE MIBs (CSCdj21675)

SNMP Sets for the LANE server MIBs, CISCO-LECS-MIB, CISCO-LES-MIB and CISCO-BUS-MIB are not supported for the 2.2(2) release.

Note The CISCO-LEC-MIB remains unchanged with this release (it continues to support only SNMP Gets and does not support SNMP Sets).

Spanning Tree BPDU's Are Not Flooded when STP is Disabled (CSCdj37972)

If spanning tree is disabled on a VLAN, from the console or SNMP, the per port address table entries are not updated. If BPDU's are received by the switch, they will be dropped, instead of being flooded.

If this is done on a network using spanning tree, this could potentially cause loops to form since the switch will continually drop BPDUs.

Note This can also happen when moving a port from one VLAN to another.

This problem will occur only when disabling spanning tree or when moving a port from a VLAN to another VLAN when spanning tree is disabled. If the switch is (re)booted with spanning tree configured as disabled, the proper address entry will be created on each of the ports.

Perform either of the following to correct this situation:

  • Reset the switch.

  • Reset the address table for all ports.
