Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S5
Workaround: There is no workaround.
• CSCee18679
Symptoms: When you use snmpget to retrieve information directly from the ifIndex table, the
following error message is generated:
No Such Instance currently exists at this OID.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(26)S.
Workaround: Do not snmpget. Rather, use snmpwalk or snmpgetnext.
• CSCee43259
Symptoms: In the case of a Cisco 12000 series router using Supervisor Engine 3 ISE QOC12 ATM
card, Route Processor (RP) may hang for about 15-20 minutes and crash when the following two
steps are done:
Conditions: * Configure 1K ATM PVCs (1K ATM sub-interfaces) with a class-default (queue- limit)
based service-policy configured on all of the PVCs (service-policy should be configured under each
PVC to see RP hangs and crash).
* On removing the above 1k ATM PVCs (sub-interfaces), RP hangs for about 15-20 minutes before
the user can regain control.
The following warning message may show up when deleting the ATM sub-intfs:
%WARNING: Features on ATM6/0.1 haven’t been removed Please wait for approximately ten
minutes and retry. % Removal of physical interfaces is not permitted.
* On adding the 1K sub-intfs again (second attempt), RP crashes. This RP crash is reproducible.
Workaround: There is no workaround.
• CSCee49035
Symptoms: An incorrect update-source interface is selected for a multicast tunnel interface in an
MVPN configuration.
Conditions: This symptom is observed when the provider edge (PE) router is also an ASBR with
eBGP peers or has non-VPNv4 peers with higher IP addresses than the peer that has VPNv4 enabled.
MVPN requires that the BGP update source address of a VPNv4 peer is selected as the MTI source
address.
Workaround: There is no workaround.
• CSCee66058
Symptoms: SNMP users that have MD5 configured may become lost after a switchover in an RPR+
environment.
Conditions: This symptom is observed on a Cisco 7500 series and Cisco 12000 series that run
Cisco IOS Release 12.0(27)S1 in RPR+ mode.
Workaround: There is no workaround.
• CSCee81490
Symptoms: MALLOCFAIL messages may be generated during an attempt to allocate large negative
and positive memory blocks in the "cpf_process_ipcQ" process:
%SYS-2-MALLOCFAIL: Memory allocation of -1622998781 bytes failed from
0x60B5BE48, alignment 0
