Open and Resolved Caveats in Software Release 4.5(7)

Resolved Caveats in Software Release4.5(8)

Note For a description of open caveats in software release 4.5(8), see the “Open Caveats in Software

Release4.5(8)” section on page27.

This section describes caveats resolved in software release 4.5(8):

• When a port on a WS-X5012 or WS-X5012A module is disabled, the OutOctet counters might report

an incorrect value if the value is larger than can be displayed with 32 bits. This problem is resolved

in software release 4.5(8). (CSCdr48865)

• The Catalyst 5000 family switch is unable to resolve DNS names if the DNS server has more than

seven entries. This problem is resolved in software release 4.5(8). (CSCdr80835)

• A system reset might occur during SNMP polling of the switch ports (SWPoll64bCnt) if a module

goes on- and off-line frequently. This problem is resolved in software releases 4.5(8) and 5.4(3).

(CSCdr41609)

• If you clear a VLAN from a trunk port and disable spanning tree on the switch, STP BPDUs for that

VLAN are still received on the trunk port and the switch floods the BPDUs to all other ports in that

VLAN. This situation might lead to spanning tree instabilities and Fast EtherChannels getting

err-disabled. This problem is resolved in software release 4.5(8). (CSCdr228643)

• Repeatedly removing and creating an entry in cseStaticExtRouterTable using SNMP causes a

system reset. This problem is resolved in software releases 4.5(8) and 5.4(3). (CSCdr40101)

• Installing a Multicast Group Destination Address (GDA) into a static CAM for a specific VLAN is

not allowed. This problem is resolved in software release 4.5(8). (CSCdr49350)

• A memory corruption occurs if you turn on IGMP Snooping and configure an EtherChannel

connection. The corruption occurs when the EtherChannel port status changes from

Administratively Down to Up. This problem is resolved in software release 4.5(8). (CSCdr24709)

• Under certain conditions the CPU on the supervisor engine might stay at 90 percent or higher

utilization. This situation might affect management and essential operation of the system. Switching

of data traffic will be unaffected. This problem is resolved in software release 4.5(8). (CSCdr71528)

• If you Telnet to a Supervisor Engine III running software release 4.5 and then Telnet to another

device, displaying a large list or file can cause the Telnet session to hang. This problem is resolved

in software release 4.5(8). (CSCdm79404)

• When large amounts of data display during a Telnet session, the Telnet session will sometimes hang.

This problem usually happens if you have set the screen length to 0 and long show commands are

being displayed or if you have cut and pasted several show commands onto the window.

Workaround: Avoid using cut and paste in a Telnet session and set the screen length to non-zero.

This problem is resolved in software release 4.5(8). (CSCdp47176, CSCdr40184)
