Release Notes for Catalyst5000 Family Software Release4.x
OL-2306-01
Usage Guidelines, Restrictions, and Troubleshooting
• If you plan to use the Gigabit EtherChannel module (WS-X5410) with Supervisor Engine I or II or
in a Catalyst 5000 series chassis, use supervisor engine software release 4.3(1) or later in
conjunction with Gigabit EtherChannel module software release 4.3(1) or later. This hardware was
not fully tested with the Gigabit EtherChannel module in earlier releases. The Gigabit EtherChannel
module is supported in the Catalyst 5500 series chassis with a Supervisor Engine III module in
software release4.2(1) and later.
• If you need to download configuration files to many switches in a network topology with redundant
EtherChannel links, download the configuration at each switch manually using the configure
network command. Otherwise, in some situations, a broadcast storm can occur.
• The Catalyst 5500 series switches support redundant supervisor engine modules. Redundant
supervisor engines must be the same type (both Supervisor Engine II or both Supervisor EngineIII).
You can use any combination of Supervisor Engine III and III F modules in a redundant
configuration provided the feature card on both modules is the same (both EARL1+, both NFFC, or
both NFFC II).
• A maximum of seven ATM modules or RSMs, in any combination, can be installed in a
Catalyst5500 or 5509 switch.
Caution If you plan to run both the Ethernet LANE software and the Token Ring LANE software, you must
run them on separate ATM LANE modules.
• To use the dynamic port VLAN assignment feature in a Catalyst5000 family switch that contains a
Supervisor Engine I module, the Supervisor Engine I module must be at hardware revision1.7 or
higher. All hardware revision levels of Supervisor Engine II and III modules support the dynamic
port VLAN assignment feature.
• If both PHY ports on an FDDI module are connected, you should disable and reenable them
together. If you disable and reenable only one port, a broadcast storm might result.
• Under certain conditions, etherHistoryUtilization is not reported correctly if the counter value wraps
between the two consecutive samples.
Workaround: Reduce the sample interval. (CSCdk09592)
