Open and Resolved Caveats in Software Release 4.5(6)
This section describes caveats resolved in software release 4.5(6):
• If a large number of RMON history, alarm, and event entries are continuously deleted and added,
the RMON alarmTimer experiences a memory allocation problem. This problem is resolved in
software release 4.5(6). (CSCdp58575)
• When a FDDI port is trunking, a fast link flap may cause the port to stop trunking. This problem is
resolved in software release 4.5(6). (CSCdp72267)
• Supervisor Engine III experiences an exception when receiving an rmon_set_historyEnable entry.
This problem is resolved in software release 4.5(6). (CSCdp67262)
• A port status mismatch might occur on Catalyst 5000 family switch module WS-X5225R and
WS-X5234 ports that are directly connected to ports on the WS-X6248-RJ-45 Catalyst 6000 family
switch module. This problem is resolved in software release 4.5(6). (CSCdp61755)
• If you define VLAN groups in the VMPS configuration database file, there may not be enough free
memory to save this information. This problem is resolved in software release 4.5(6).
(CSCdp68303)
• TACACS+ might experience an exception if access to an invalid socket is attempted. This problem
is resolved in software release 4.5(6). (CSCdp40197)
• With the Catalyst 5000 family switch running software release 4.5(1) and later, the ifOutUcastPkts
and ifInUcastPkts counter sometimes decrements instead of increments on 10/100 Ethernet ports.
This problem is resolved in software release 4.5(6). (CSCdp71615)
• If you configure a Catalyst 5000 family switch for VTP client mode with redundant Supervisor
Engine IIIGs (WS-X5550s), there is no connectivity to devices on the WS-X5101 after the switch
reloads. This problem is resolved in software release 4.5(6). (CSCdp68378)
• Intermittently, PVST+ conversion is not performed when BPDUs go from a non-native VLAN on
an 802.1Q trunk to an access port and STP is disabled. This problem is resolved in software release
4.5(6). (CSCdp81050)
• If a port comes up as an individual port and there is a channel in its EBC range, the port gets the
default channel port setting whether the port is connected or not. From the point of view of a Fast
Ethernet channel, the switch appears to be sending traffic through a disconnected port.This problem
is resolved in software release 4.5(6). (CSCdp78923)
• Supervisor Engine II in a Catalyst 5500 running software version 4.5(5) will continually reboot.
This problem is resolved in software release 4.5(6). (CSCdp74698)
• TrafficDirector NetFlow monitoring stops on the Network Analysis module (WS-X5380) after the
module is reset. This problem is resolved in software release 4.5(6). (CSCdp10760)
• Entering the show mls command after changing the flowmask from destination to full can cause a
system exception. This problem is resolved in software release 4.5(6). (CSCdp02406)
• When using VMPS on ports connected to routers running HSRP that are not configured to use the
burned-in address, the Catalyst 5000 family switch might reset when the active HSRP router is shut
down.
Workaround: Configure standby use-bia on the router interfaces for the HSRP (standby uses the
interfaces burned in address [bia]). This problem is resolved in software release 4.5(6).
(CSCdp51787)
• Occasionally, when MLS detects a host move, the show mls entry command might display no
entries. This problem is resolved in software release 4.5(6). (CSCdp39218)
• VTP updates received through other trunks might enable disabled trunks that have a default VLAN
other than 1. This problem is resolved in software release 4.5(6). (CSCdp39638)
