failed was 0, error code 0 Shutting down diags in slot {#}
Board will reload.
Conditions: This symptom is observed for any release of Cisco IOS software when you attempt to
run field diagnostics on a standby PRP that has 4 GB of memory.
Workaround: There is no workaround.
• CSCsk36276
Symptoms: Traceback seen at tfib_post_table_change_label_request_needed.
Conditions: Occurs during SSO switchover on a Cisco 7606 router.
Workaround: There is no workaround.
• CSCsk36552
Symptoms: Some packet flows may be dropped when the next-hop is load-shared between
MPLS-TE tunnel and physical interface. The next-hop entry for the physical interface is invalid in
Hardware-CEF table in ingress Line-Card during this problem. This cause the some packet flows
which look up the invalid entry as the result of hash calculation to be dropped. The other flows which
looks up the tunnel interface are not affected.
You can check the detail of hardware-CEF table for this problem by entering the show ip
hardware-cef prefix detail command in Engine 3 and Engine 5.
Conditions: This problem occurs when the next-hop is load-shared between MPLS-TE and physical
interface. This problem may be observed when using Engine 3 or Engine 5 as the ingress Line-Card
on GSR.
Workaround: There is no workaround.
• CSCsk47914
Symptoms: Traffic forwarding stops after micro-reloading the egress card when E4+ is ingress.
Conditions: Occurs after micro-reload of the egress line card
Workaround: 1. Micro-reload the E4+ line card. 2. Use the clear cef line card ingress card slot#
command to recover the traffic.
• CSCsk49843
Symptoms: E3 4xOC12 ATM line card may crash on enabling feature mode.
Conditions: Occurs when IPv4 VPN routing/forwarding (VRF) is configured on an IPv6-enabled
interface.
Workaround: Apply an IPv6 ACL to “permit any any”.
• CSCsk71509
Symptoms: Line card stops forwarding after the ip default-network 192.168.228.0 command is
entered.
Conditions: Occurs on a LC Engine 5 with 12000-SIP-601 and running Cisco IOS Release
12.0(32)SY1 or 12.0(32)SY4. Problem also occurs on SPA-8XCHT1/E1 and 10Gigabit.
Workaround: Use Interior Gateway Protocol (IGP) to propagate the default route 0.0.0.0. BGP or
OSPF also work. You can also add static route 0.0.0.0/0.
• CSCsk81155
Symptoms: OSPFv3 loses hello packets causing neighbors to flap.
