Cisco Bug: CSCvu63340 - Change default value for in band monitoring interval from 1 second to 5 seconds
Jul 28, 2020
- Cisco Unified Computing System
Known Affected Releases
Symptom: When using In Band Management, ICMP Frames are sent from each CIMC to the default gateway for a health check every second. When 3 ICMP frames are missed, this triggers CIMC failover from Managing instance to other instance. This failover sends a GARP northbound to the network to notify the network of topology change. On large environments, this happens many many times. Conditions: General operation while using In Band Management with UCSM and large environments with many blades / service profiles.
