Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S
–
The main interface is also used with an IP address assigned to it.
–
The VRF VLAN subinterface receives a packet such as an ARP or ICMP packet that is punted
to the CPU of the line card.
For the BGP neighbor to go down, in addition to the above-mentioned conditions, the neighbor
ip-address password string command must be configured.
Workaround: If you must use a VRF VLAN subinterface, create another subinterface for non-VRF
communication on the same main interface.
Alternate Workaround: Do not use a VRF VLAN subinterface.
• CSCef93832
Symptoms: A router that reboots enters an infinite loop.
Conditions: This symptom is observed after a router has crashed and when the ROMMON does not
gracefully recover during the rebooting process.
Workaround: There is no workaround.
• CSCef94525
Symptoms: A port adapter that is installed in a VIP or FlexWAN and that is configured with more
than 38 multilink bundles may crash.
Conditions: This symptom is observed on a Cisco 7500 series and Cisco 7600 series when
distributed CEF switching is disabled either through entering the no ip cef distributed command or
through a FIB-DISABLE event.
Workaround: There is no workaround.
• CSCef94619
Symptoms: A VIP may crash while forwarding packets or a watchdog timeout crash may occur on
the VIP during statistics collection.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with an RSP4 and
that runs Cisco IOS Release 12.0(26)S4.
Workaround: There is no workaround.
• CSCef96458
Symptoms: The OAM emulation status is displayed incorrectly.
Conditions: This symptom is observed when you enter the show atm pvc command.
Workaround: There is no workaround.
• CSCef96652
Symptoms: The offered rate counter in the output of the show policy-map interface command is
inaccurate.
Conditions: This symptom is observed on a Cisco 12000 series when very high traffic rates are used.
Workaround: There is no workaround.
• CSCef97340
Symptoms: On an HA-capable router that is configured for distributed IPv6 multicast, the line cards
may not perform distributed CEF switching of multicast traffic.
Conditions: This symptom is observed on a Cisco router that is configured with redundant RPs.
Workaround: There is no workaround for an HA-capable system. Removal of the RRP should restore
proper operation by restoring the MRIB clients and MFIB tables on the line cards.
