CSCsj86839
Symptoms: Field diagnostics for a card such as the SIP-401, SIP-501, SIP-601 fails with messages:
"Timeout waiting for Field Diag individual test completion
Field Diagnostic: ****TIMEOUT FAILURE**** slot 4: first test failed: 163,
SPA LPBK damsl, error 0
Field Diag eeprom values: run 44 fail mode 3 (TIMEOUT FAILURE) slot 4
last test failed was 163, error code 0
Shutting down diags in slot 4"
Moreover, depending upon which verbosity and debugging flags are enabled you may see a series
of messages such as:
"Field Diag Misc Services requested for a slot (4) not in Field Diag mode, dropping
request."
This occurs until the slot is reloaded with the command hw-module slot # reload
Conditions: This problem occurs when field diagnostics is run on the SPA, “SPA-10x1GE” residing
in any Jacket card.
Workaround: There is no workaround.
CSCsj87371
Symptoms: In case that MPLS Traffic Engineering Tunnel (TE Tunnel) and Fast Reroute (FRR) are
configured on 12000 Series router, FRR backup Tunnel does not restore MPLS LDP/TDP
encapsulating packets inputting from Engine 4 Line Card.
Conditions: When Next hop is Head-end LDP/TDP over TE Tunnel and FRR become active, the
labeled packets are not protected by the backup TE Tunnel so it causes continuous packet drop until
new path is installed.
Workaround: There is no workaround.
CSCsj89407
Symptoms: The tx-ring-limit value configured in PA-2CT3 may reset to its default value.
Conditions: Occurs while doing soft OIR of PA-2CT3.
Workaround: There is no workaround.
CSCsj90463
Symptoms: Holddown timer value is different in “show bfd nbr detail” and “show bfd neighbor”.
The detailed output of “show bfd neighbor” command displayed holddown timer value for async
mode where as the summarized output showed the holddown timer value for echo mode. Change had
to be made to have holddown field in both summarized and detailed output of “show bfd neighbor”
to display same value.
Conditions: When holddown value in “show bfd summary” and “show bfd neighbor detail” are
compared.
Workaround: There is no workaround.
CSCsj91286
Symptoms: This issue is a traceback seen on boot when upgrading or downgrading an image. The
traceback seen is:
’%MBUS_C2W-3-SPA_UNKNOWN_C2W_DEVICE: cannot find SPA’s C2W device for slot:’, and
running config for all SPA’s may be lost from an engine 5 card.
Conditions: This issue is due to the Mbus Agent ROM and Mbus Agent RAM.
