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:
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.
 | 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.
| 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. |
The following are known conditions as of this version of the software release.
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.
It is not possible to run CGMP and have Address Filtering in use at the same time. CGMP will override filter table entries.
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 for the LANE server MIBs, CISCO-LECS-MIB, CISCO-LES-MIB and CISCO-BUS-MIB are not supported for the 2.2(2) release.
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.
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:
The following conditions have been corrected with the 2.2(1) version of the software release. In addition, all corrections applied to the 2.0(3) and 2.1(2) releases are included in that release.
