Caveats

Resolved Caveats—Cisco IOS Release 12.0(32)S12

• CSCsi68795

Symptoms: A PE that is part of a confederation and that has received a VPNv4 prefix from an

internal and an external confederation peer, may assign a local label to the prefix despite the fact

that the prefix is not local to this PE and that the PE is not changing the BGP next-hop.

Conditions: The symptoms are observed when receiving the prefix via two paths from confederation

peers.

Workaround: There is no workaround.

Further Problem Description: Whether or not the PE will chose to allocate a local label depends on

the order that the multiple paths for this VPNv4 prefix are learned. The immediate impact is that the

local label allocated takes up memory in the router as the router will populate the LFIB with the

labels.

• CSCsi77983

Symptoms: NetFlow cache runs out of space for new flow entry when customer uses heavy traffic.

Conditions: Large amount of traffic which could exhaust the NetFlow cache.

Workaround: There is no workaround.

• CSCsi84089

Symptoms: A few seconds after OSPF adjacencies come up, a router crashes because of a bus error.

Conditions: This symptom is observed on a Cisco router that functions as an ISR that is configured

for OSPF.

Workaround: Add area 0 in the OSPF VRF processes.

Alternate Workaround: Enter the no capability transit command in the OSPF VRF processes.

• CSCsj30417

Symptoms: In Eng3 ATM, when a subinterface flaps, traffic to certain destinations is forwarded to

the wrong subinterface.

Conditions: This symptom is observed in Cisco IOS Release 12.0(32)S05 and 12.0(32)S06. The

symptom is not found in Cisco IOS Release 12.0(31)S2.

Workaround: There is no workaround; however, reloading the line card solves the problem.

• CSCsj49293

Symptoms: The interface output rate (214 Mb/s) is greater than the interface line rate (155 Mb/s).

Conditions: This symptom is observed with a Cisco 7600/7500/7200-NPE400 and below. That is,

PA-POS-2OC3/1OC3 (PULL mode).

Workaround: There is no workaround.

Further Problem Description: From the Ixia, packets are transmitted at 320 Mb/s. On the UUT

(Cisco 7600), the outgoing interface (POS-Enhanced Flexwan) shows the output rate as 200 Mb/s.

But the interface bandwidth is 155 Mb/s.

• CSCsj50773

Symptoms: Performing the snmpwalk on the ipRouteTable MIB may cause high CPU and reloads.

Conditions: This symptom is observed on a router that is running Cisco IOS Release 12.4(13b) or

later releases.
