Caveats

Resolved Caveats—Cisco IOS Release 12.0(30)S5

ISO CLNS

• CSCsb34032

Symptoms: A router may reload unexpectedly when you remove the IS-IS configuration at the

interface or router level.

Conditions: This symptom is observed on a Cisco router when the following conditions are present:

–

The router is HA-capable.

–

The isis protocol shutdown interface configuration command is enabled on the interface.

–

You enter an interface configuration command that enables IS-IS such as an isis command, a

clns command, or the ipv6 router isis before you enter the a router configuration command

such as the net command.

When you now remove the IS-IS configuration at the interface or router level, the router may reload.

Workaround: Remove the isis protocol shutdown interface configuration command before you

remove IS-IS from the interface or router level.

• CSCsc63871

Symptoms: When IS-IS and CLNS are configured, a router may enter a state in which only one

adjacency is shown in the output of the show clns interface command, even though the show clns

neighbors command may correctly display all the neighbors that are connected to the interface.

When this situation occurs and any one of the neighbors on the segment goes down, all routing

updates may be lost. The single adjacency is torn down and despite the fact that the output of the

show clns neighbors command still shows the neighbors, routing stops because there are no

adjacencies.

Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.2(18)S1 or

Release 12.3(9b) when an adjacency goes down while it is still in the INIT state. The symptom

occurs because the adjacency counter is incorrectly decremented. The symptom may also occur in

other releases.

Workaround: Enter the shutdown interface configuration command followed by the no shutdown

interface configuration command on the interface that reports only one adjacency.

Alternate Workaround: Enter the clear clns neighbors command on the affected router.

Miscellaneous

• CSCeb05456

Symptoms: A Cisco platform may reset its RP when two simultaneous write memory commands

from two different vty connections are executed, and messages similar to the following may appear

in the crashinfo file:

validblock_diagnose, code = 10

current memory block, bp = 0x48FCC7D8, memory pool type is Processor data check, ptr

= 0x48FCC808

next memory block, bp = 0x491AC060, memory pool type is Processor data check, ptr =

0x491AC090

previous memory block, bp = 0x48FCBBE8, memory pool type is Processor data check, ptr

= 0x48FCBC18

The symptom is intermittent and is related to the way NVRAM is accessed.

Conditions: This symptom is observed on a Catalyst 6000 series Supervisor Engine 720 that runs

Cisco IOS Release 12.2(18)SXD but is platform- and release-independent.
