Resolved Caveats—Cisco IOS Release 12.0(27)S3
Workaround: Prevent the MIB from being polled by explicitly configuring an SNMP view in the
Cisco IOS configuration. To prevent this MIB from being accessed via any community strings,
create a view and apply the view to all communities configured, such as:
snmp-server view NOMEMPOOL iso included snmp-server view NOMEMPOOL
ciscoEnhancedMemPoolMIB excluded snmp-server community public1 view NOMEMPOOL ro 6
snmp-server community public2 view NOMEMPOOL ro 7 snmp-server community public3 view
NOMEMPOOL ro 8
The specific MIB that is being blocked is the ciscoEnhancedMemPoolMIB MIB
(1.3.6.1.4.1.9.9.221).
Once the configuration is in place, the router must be reloaded to clear the IPC cache and free the
memory.
• CSCee78266
Symptoms: A Cisco 7500 series may reload in an indefinite loop when you unintentionally enter the
show list number hidden command.
Conditions: This symptom is observed when you, for example, abbreviate the show line 2000
command as the show li 2000 command and actually execute the show list 2000 hidden command.
Workaround: Do not abbreviate the show line command as the show li command but enter the full
command.
• CSCin44135
Symptoms: A slave RSP running in HSA mode may crash with a cache parity exception.
Conditions: This symptom is observed on a Cisco 7500 series and occurs only when the slave RSP
is an RSP8 or RSP16 that runs in HSA mode.
Workaround: There is no workaround.
The fix for this caveat turns off the L3 cache by default on an RSP8 or RSP16 that functions as a
slave and that runs in HSA mode; you do not need to do anything specific to turn off L3 cache by
default on an RSP8 or RSP16 that functions as a slave and that runs in HSA mode.
For an RSP8 or RSP16 that functions as a slave and that runs in a non-HSA mode such as RPR, you
can turn off the L3 cache by entering the l3 cache bypass command on the master RSP while the
slave RSP8 or RSP16 still runs in a non-HSA mode.
Because the slave RSP performs non-CPU intensive operations, regardless of the mode of operation,
turning off the L3 cache does not have any undesirable impact.
Interfaces and Bridging
• CSCec15909
Symptoms: In a High Availability (HA) environment with Stateful Switchover (SSO) enabled and
while trying to configure framing for T1 on T3 PA, the standby route processor (RP) gets reloaded
giving a “CCB playback failed” error.
Conditions: The defect is seen with SSO or RPR-Plus enabled on T3 family of port adaptors. The
trigger is the change in framing configuration for T1 on T3 PA.
Workaround: Administratively shutdown all interfaces on T1 before changing the framing.
