Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

Workaround: Use priority and with absolute-value (explicit) policer.

• CSCsl71254

Symptoms: A Cisco 7609-S with RSP720 processor, using ES20 line card, and running Cisco IOS

Release 122-33.SRB2 crashes.

Conditions: Occurs when configuring L3 subinterface with dot1Q NATIVE encapsulation on ES20

card interface, where already service-instance configured.

Workaround: There is no workaround.

• CSCsl71540

Symptoms: Router reloads when the sh ip /jointfilesconvert/422273/bgp options command is entered.

Conditions: This is seen in releases where CSCsj22187 is fixed.

Workaround: There is no workaround.

• CSCsl72281

Symptoms: After a Cisco 7600 series router reloads, host routes created by DHCP relay process for

DHCP clients that are connected to unnumbered VLAN interfaces point to wrong VLAN interface.

Conditions: This symptom occurs when interface-index value parameter on the router changes after

the router reloads. This parameter is stored in DHCP bindings database on TFTP or FTP server. It

is recalculated in case of the router reloading and may change if a new interface is added or existing

interface is removed from the configuration. For example, a single interface VLAN is added to the

configuration prior to the router reloading.

Workaround: There is no workaround.

• CSCsl72285

Symptoms: MLP bundle may fail to come up when a queuing policy is applied under the VT.

Conditions: The symptom is observed on a Cisco 10000 series router where a queuing policy is

applied under the VT in an LNS.

Workaround: Bring up the MLP bundle and then apply the queuing policy under the VT in an LNS.

• CSCsl72636

Symptoms: A Cisco router may experience traffic drop on frame-relay point-to- point subinterfaces

during a SSO/NSF failover. This only occurs when a large number of frame-relay point-to-point

interfaces are used.

Conditions: This symptom is observed on a Cisco router that is running either Cisco IOS Release

12.2(32)SB or later releases, or Cisco IOS Release 12.2(32) SRB or later releases, that is configured

for Stateful-Switchover (SSO) and Nonstop Forwarding (NSF).

Workaround: There is no workaround.

• CSCsl72774

Symptoms: A router may run out of memory and fail malloc due to a memory leak.

Conditions: This problem only occurs on distributed platforms (like the Cisco 7600/Catalyst 6500)

when the CEF consistency checkers have been enabled. By default, the CEF consistency checkers

are disabled. When the CEF consistency checkers are turned on, memory is leaked on the RP, SP

and line cards.

If you want to use the consistency checkers, then do so for only short periods of time. For example,

use the consistency checkers while diagnosing network problems.
