Cisco Bug: CSCsy79962 - Disable fabric on peer RSP before power cycle
May 10, 2018
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Basic Description: When the active RSP decides to reset standby RSP, for example per user CLI request, the active RSP needs to disable the fabric manager on the standby RSP prior to the reset to avoid a temporary short packet hit on the in-flight packets travelling through the standby RSP. Symptoms: A less than 2 millisecond traffic hit can happen on in-flight packets travelling through the standy RSP fabric, if the standby RSP is reset without the fabric manager being notified of this event ahead of time, so it can gracefully shut down the standby RSP fabric prior to the standby RSP reset. Condition: A reset of the standby RSP such as one triggered by the "hw-module location <standby RSP> reload command" can trigger the temporary short packet hit described above.
