Release Notes for Catalyst5000 Family Software Release4.x

OL-2306-01

Open and Resolved Caveats in Software Release 4.5(13a)

–

Three-port Gigabit Ethernet Module—Provides three 1000BASE-SX Ethernet ports; supports

ISL and 802.1Q trunking, broadcast suppression in hardware, 802.3x flow control, and is full

duplex only. This module does not support Gigabit EtherChannel port aggregation.

(WS-X5403)

–

NetFlow Feature Card (NFFC)—Enables new features for the Supervisor Engine III, including

MLS, IGMP snooping, and Protocol Filtering. (WS-F5521)

Open and Resolved Caveats in Software Release 4.5(13a)

Open Caveats in Software Release4.5(13a)

Note For a description of caveats resolved in software release4.5(13a), see the “Resolved Caveats in

Software Release4.5(13a)” section on page17.

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

• When operating at 10MB, a disabled port on a WS-X5224, WS-X5012, WS-X5012A, or WS-X5014

module will continue to transmit link pulses. This causes the link-partner port to stay up. There is

no workaround. The problem exists in 4.x, 5.x, and 6.x releases of the Catalyst operating software.

(CSCdw25922)

• On Catalyst 5500 series switches, Gigabit Ethernet autonegotiation is broken on the Gigabit

Ethernet uplink module (WS-U5534) in supervisor engine software releases 4.5(11), 4.5(12), and

4.5(13). Autonegotiation fails only if the other end of the link is also connected to a WS-U5534

uplink module. There is no problem if the other end of the link is connected to another Gigabit

Ethernet module such as the 3- or 9-port modules.

Turning off autonegotiation to avoid the problem is not recommended as this can lead to

spanning-tree loops if you have a unidirectional link. The only workaround is to connect a WS-U5534

uplink module to a different module (not the WS-U5534 uplink module). (CSCdw21589)

• If you have multiple ATM fabric integration modules (WS-X5165) installed and you have more than

50 LECs configured on each module, a multiple-module software download to the modules can take

an excessively long time to complete. For this reason, we recommend that you download software

images one module at a time (by specifying the module number in the download command).

(CSCdk55355)

• If IGMP snooping or CGMP is disabled while protocol filtering is enabled, Layer 2 multicast

forwarding will be affected when protocol filtering is later disabled. The commands to reproduce

this are:

a. set igmp enable (or set cgmp enable)

b. set protocolfilter enable

c. set igmp disable (or set cgmp disable)

d. set protocolfilter disable
