Open and Resolved Caveats in Software Release 4.5(13)

Resolved Caveats in Software Release4.5(13)

Note For a description of caveats open in software release4.5(13), see the “Open Caveats in Software

Release4.5(13)” section on page18.

This section describes resolved caveats in software release4.5(13).

• The Catalyst 5500 series switch might crash when you make Telnet connections between the switch

and the RSM.

Workaround: Reload the switch.

This problem is resolved in software release 4.5(13). (CSCdt01088)

• Due to an issue with CGMP, multicast packet loss may be experienced when there are no receivers

in the multicast source LAN segment (for example, a source-only segment).

Workaround: Configure a static IGMP group or disable CGMP.

This problem is resolved in software release 4.5(13). (CSCdt58274)

• A Catalyst 5000 family switch with Supervisor Engine III running 4.5(8) with CGMP configured

will not install a static CAM entry for a multicast receiver on the other end of a port channel.

Workaround: Enable IGMP instead of CGMP on the core switch.

This problem is resolved in software release 4.5(13). (CSCdu05568)

• The Catalyst 5000 family switch may pause indefinitely after the 20 MB Viking FlashPC

(PCMCIA) card is hotswapped numerous times (approximately 20).

This problem is resolved in software release 4.5(13). (CSCdu23412)

• When an ISL trunk port is connected to an access port and QoS is enabled on the switch that has the

ISL trunk, the ISL header sets the user bits in the DA. Currently, the supervisor engine drops only

the packets with user bits set to 0 and 1 and forwards the packets with other bits set to the access

VLAN of the non-trunk port. The forwarded packets do not go through blocked ports.

This problem is resolved in software release 4.5(13). (CSCdu10858)
