Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S2
Workaround: Configure the neighbor device to use less than a 256 character hostname, or disable
the CDP process with the global command no cdp run.
Interfaces and Bridging
• CSCec87736
Symptoms: TX Simple Network Management Protocol (SNMP) counters do not update on Fast
Ethernet subinterfaces for distributed Cisco Express Forwarding (dCEF) traffic.
Conditions: This symptom is observed on Cisco IOS Release 12.0(26)S and Release 12.3. The
hardware is DEC21140A, and the interface receiving the traffic is not located on the same Versatile
Interface Processor (VIP).
Workaround: There is no workaround.
• CSCed08399
Symptoms: A Cisco 7500 series may generate spurious memory accesses at a VIP.
Conditions: This symptom is observed when CRTP is enabled on the interfaces of the VIP.
Workaround: There is no workaround.
IP Routing Protocols
• CSCec07636
Symptoms: When the following Open Shortest Path First (OSPF) MIB tables are queried via
snmpwalk, some interfaces may not be displayed:
- ospfNbrTable
- ospfIfTable
- ospfIfMetricTable
Conditions: This symptom is observed on any Cisco platform that runs OSPF.
Workaround: There is no workaround.
• CSCed00449
Symptoms: SAA probes that are executing on the Cisco 12000 series routers incorrectly measure
round trip time delay measurements.
Conditions: This symptom is only observed on a Cisco 12000 series router.
Workaround: Run the probe on a different Cisco platform.
• CSCed62901
Symptoms: This symptom occurs in an OSPF network topology in which a CE router (CE-1) connect
to a PE router (PE-1) that connects to two other PE routers (PE- 2 and PE-3), each of which connect
to another CE router (CE-2 and CE-3). In turn, both of these CE routers are connected to each other
(that is, CE-2 and CE-3 connect to each other).
When the link between the PE-3 and the CE-3 flaps, the OSPF route in the VRF fails to switch back
from BGP to OSPF on the PE-1.
Conditions: This symptom is observed in Cisco IOS Release 12.0 S, 12.2 S, and 12.3 T.
Workaround: Clear the ip route, clear the OSPF process, or enter the clear ip bgp * command on
the PE-1 to bring the route back from BGP to OSPF.
