bootflash command.
Workaround: There is no workaround.

Symptoms: A memory leak may occur in the IPC buffers of a Cisco router, and the output of the
show processes memory command shows that the Pool Manager process holds increasingly more
memory.

Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.0(26)S2 or 12.0(26)S3. The memory leak is triggered by the SNMP polling of specific
OIDs within the ciscoEnhancedMemPoolMIB MIB.
Workaround: Prevent the ciscoEnhancedMemPoolMIB MIB from being polled by explicitly
configuring an SNMP view. To prevent this MIB from being accessed via any community strings,
create a view and apply the view to all communities configured, as in the following example:
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 ciscoEnhancedMemPoolMIB (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.

Symptoms: When a new probe (for example, index $PROBE_ID) is created through SNMP, the
probes that have index numbers that are greater than $PROBE_ID are not shown in the output of the
show rtr configuration and show rtr operation-state commands.
Conditions: This symptom is observed when the probe is created in the CREATE_AND_WAIT state
by entering the following command:
unix_xterm>
setany -v1 $ROUTERIP public
rttMonCtrlAdminStatus.$PROBE_ID 5
In addition, there is no subsequent SNMP configuration command for the probe.
Workaround: Enter a subsequent SNMP configuration command to make the probe configuration
complete, as in the following example:
setany -v1 $ROUTERIP public \
rttMonCtrlAdminRttType.$PROBE_ID -i 1 \
rttMonEchoAdminProtocol.$PROBE_ID -i 2 \
rttMonEchoAdminTargetAddress.$PROBE_ID -o "05 00 00 02"
