Cisco Cisco IOS XR Software Release 3.2

Symptom: After performing more than 15-20 OIRs of the alarm card while it is in various stages of 
booting, show hfr command shows an UNKNOWN entry.

Conditions: On a Cisco CRS-1 single-shelf chassis, if we do more than 15-20 OIRs of AM0 or AM1 
while these nodes are booting (that is, in MBI-BOOT or MBI-RUN state), an UNKNOWN entry 
may eventually show up in the output of the show hfr command.

Workaround: The process restart invmgr command fixes this problem.

Basic Description: Following a SPA OIR operation, an error may be encountered which results in 
subsequent packet loss. This can be corrected by restarting the affected SPA. 

Symptom: The following error message is reported: %L2-BAMBI-3-ASIC_ERR : plaspa instance 
0 L2P UIDB Multi, check uidb hash table. Data arriving on the affected SPA is dropped.

Conditions: This symption is observed on Cisco CRS-1 routers Shared Port Adapters (SPA) during 
Online Insertion and Removal (OIR). 

Workaround: Consider the following workaround:

Power-down the affected SPA, wait 3 minutes, then power-up the SPA and check traffic flow.

Online insert and remove the affected SPA, wait 3 minutes, then reinsert SPA and check traffic 
flow.

Online insert and remove the SIP-800 housing the affected SPA. This must be a tertiary course 
of action as there may be other SPAs in-service housed in the SIP-800 that could be affected by 
this operation.

The following caveats are specific to the Cisco XR 12000 Series Router platform:

Basic Description: TURBOBOOT (cold boot) procedure with the -clean option cleans all files on 
the boot disk (disk0:) of all non-DSC RPs. 

Symptom: The TURBOBOOT procedure used with the -clean option cleans only the package files 
on the boot disk (typically disk0:) on the DSC. However on all other RPs in the system, all files on 
the boot disk are deleted (including any user or configuration files). 

The configuration for non-owner LRs is stored on the boot device of the RPs of those LRs (not the 
DSC). If a turboboot is issued with the -clean option when LRs are carved out, this has the effect of 
deleting the configuration on any non-owner LRs. 

Conditions: All package and user files on disk0: are deleted when TURBOBOOT starts on the 
non-DSC RPs.

Workaround: The user should back up any configuration for non-owner LRs before starting the 
turboboot and re-apply this configuration manually when the turboboot has finished. Also, any other 
user files on the disk of any RP should be backed up before starting the turboboot.

Brief Description: Class or mark policy counters multiply depending on the number of match 
criteria.

Symptom: When a QoS policy uses a class map that classifies traffic based on a number of 
match-any criteria and this policy is applied to an interface in ingress or egress direction, the show 
policy map command counters can increment in the multiples of the number of match criteria.
