Release Notes for Catalyst5000 Family Software Release4.x

Open and Resolved Caveats in Software Release 4.5(1)
On some switch ports, if you enable port security on the port before the port is in the spanning tree
forwarding state, port security might shut the port down. This problem occurs only if BPDUs,
broadcast packets, or other traffic is received on the port before the port enters the forwarding state.
This problem affects these products:
WS-C2926—Catalyst 2926 switch
WS-X5223—24-port 3 segment 100BASE-TX (RJ-45 connector)
WS-X5224— 24-port 10/100BASE-TX (RJ-45 connector)
WS-X5020—48-port 4 segment 10BASE-T (Telco connector)
WS-X5010—24-port 10BASE-T (Telco connector)
WS-X5014—48-port 10BASE-T (RJ-45 connector)
WS-X5012—48-port 10BASE-T (Telco connector)
WS-X5012a—48-port 10BASE-T (Telco connector)
WS-X5013— 24-port 10BASE-T (RJ-45 connector)
Workaround: Enable the port security feature after the port is in the forwarding state (use the
showspantree mod_num/port_num command to verify the spanning tree state). This problem is
resolved in software release4.5(1). (CSCdk73206)
Under some circumstances, several ports might incorrectly be assigned the same ifIndex value (you
can see the ifIndex values for ports using the show port command). If multiple ports share an
ifIndex value, when you change the configuration on one port other ports with the same ifIndex
value might be affected. If this problem occurs, clear the entire switch configuration using the clear
config all command (make sure you back up your switch configuration before entering this
command or your configuration will be lost) and reset the switch. This problem is resolved in
software release4.5(1). (CSCdk74506)
In some cases, after a switchover from the active (slot1) to the standby (slot2) supervisor engine,
the uplink ports on the previously active supervisor engine (slot1) fail to come online. You might
see this message:
%SYS-3-PORT_SSUPFAIL:Failed to bring up ports on standby supervisor
Workaround: Disable the standby ports using the set standbyports disable command and then
reenable them using the set standbyports enable command. If the ports still fail to come online,
reset the standby supervisor engine. This problem is resolved in software release4.5(1).
(CSCdk73705)
If a Catalyst5000 family switch is configured as a VTP client and its only connection to the VTP
server is through a port on the Gigabit EtherChannel module (WS-X5410) that is configured as an
IEEE 802.1Q trunk with its native VLAN other than VLAN1, when the system is reset the trunk
port might fail to enter trunking mode after the system comes online (the show trunk command
output shows the trunk in the “inactive” state).
Workaround: Reset the module on which the trunk port is located or set the native VLAN of the
trunk port to VLAN1. This problem is resolved in software release4.5(1). (CSCdk77956)
