8 Release Notes for Catalyst 6000 Family Software Release 5.x

Open and Resolved Caveats in Software Release 5.3(4)CSX

• The set port qos trust command and the trust-ipprec and trust-dscp port keywords are not

allowed on 10-, 10/100-, and 100 Mbps ports. Instead, conﬁgure ACLs with the trust-cos,

trust-dscp, and trust-ipprec ACE keywords. Note that the trust-cos port keyword can be used

on 10-, 10/100-, and 100 Mbps ports to enable receive queue drop thresholds.

• 24-port 100FX Switching Modules (WS-X6224-100FX-MT) with a hardware version of 1.1 or

lower only support IEEE 802.1Q VLAN trunking; they do not support ISL trunking. Do not

conﬁgure ISL trunks on 24-port 100FX Switching Modules (WS-X6224-100FX-MT) with a

hardware version of 1.1 or lower. The restriction against ISL VLAN trunking is the only known

problem with hardware version 1.1 or lower of these modules. If you do not require ISL VLAN

trunking, these modules are fully functional. The ISL VLAN trunking problem has been

corrected in hardware version 1.2 or later of these modules. If you wish to return a

WS-X6224-100FX-MT module with a hardware version of 1.1 or lower, contact Cisco Systems.

You can identify WS-X6224-100FX-MT hardware versions using one of the following two

methods:

— Command-line interface (CLI) method—Use the show version command to identify the

hardware version of the WS-X6224-100FX-MT module as follows:

console> show version

< ... output truncated ... >

Mod Port Model Serial # Versions

--- ---- ------------------- ----------- --------------------------------------

< ... output truncated ... >

5 24 WS-X6224-100FX-MT SAD02470006 Hw : 1.1

< ... output truncated ... >

console>

The example shows a WS-X6224-100FX-MT module with a hardware version of 1.1; this

version does not support ISL VLAN trunking.

— Physical inspection method—Look for the part number is printed on a label on the outer edge

of the component side of the module. Versions 73-3245-04 or lower do not support ISL

trunking.

• There is a cabling issue with the 48-Port 10/100TX Switching Module (WS-X6248-TEL). The

WS-X6248-TEL module RJ-21 connectors do not support Category 3 RJ-21 telco connectors

and cabling. Using Category 3 connectors and cabling causes carrier sense errors. The module's

connectors are keyed for Category 5 telco connectors and cables. You must use Category 5 RJ-21

telco connectors and cables.

• We recommend that you do not use more than 1500 multicast groups with GMRP. This restriction

does not apply to IGMP.

Open and Resolved Caveats in Software Release 5.3(4)CSX

This section describes open and resolved caveats in supervisor engine software release 5.3(4)CSX.

Open Caveats in Software Release 5.3(4)CSX

This section describes open caveats in supervisor engine software release 5.3(4)CSX.

• If you remove a line module at the same time as you remove an active supervisor from a Catalyst

6000 family switch that is in a redundant supervisor conﬁguration, the switch may become

unreachable. To prevent this, wait at least 5 seconds after removing an active supervisor to allow

the switchover to occur before you remove a line card (CSCdp59829)
