Release Notes for Catalyst5000 Family Software Release4.x
OL-2306-01
Open and Resolved Caveats in Software Release4.1(3)
• When UplinkFast is enabled on a switch with a supervisor engine with an EARL daughter card
installed, the switch might respond slowly to CLI commands and software image downloads.
However, switch performance and spanning tree processing are not affected. This problem is
resolved in software release 4.2(1). (CSCdk39115)
• On a Catalyst 5000 family switch with a Supervisor Engine III, if the “System Uptime” (shown in
the output of the show version command) reaches 49days, 17hours, and 3minutes (2
32
seconds),
some switching modules might reset. This problem is resolved in software release4.2(1).

Open Caveats in Software Release4.1(3)
Note For a description of caveats resolved in software release 4.1(3), see the “Resolved Caveats in
Software Release4.1(3)” section on page72.
This section describes open caveats in Catalyst5000 family software release4.1(3).
Caution We do not recommend using the Token Ring modules (WS-X5030 and WS-X5031) with supervisor
engine release 4.1(3).
• If you have redundant Fast EtherChannel links and redundant Gigabit Ethernet links, and UplinkFast
is enabled, Fast EtherChannel may be incorrectly chosen as the primary path.
Workaround: Manually adjust the port costs. (CSCdk02273, CSCdk10855)
• A port on the three-port Gigabit Ethernet module (WS-X5403) might not establish a link with
certain Gigabit Ethernet NICs if autonegotiation is enabled on the port. When autonegotiation is
disabled on the port, a link is established normally. (CSCdk29940)
• A Catalyst 5500 switch might reload continuously when the SNMP historyControlInterval.x is set
to a very small number, such as 2seconds.
Workaround: In crease the historyControlInterval.x to a larger number, such as 30 seconds, or
disable RMON on the switch by entering the set snmp rmon disable command. (CSCdk23780)
• On a Catalyst 5000 family switch with a Supervisor Engine III, if the “System Uptime” (shown in
the output of the show version command) reaches 49days, 17hours, and 3minutes (2
32

some switching modules might reset. (CSCdk32229)
