Cisco Bug: CSCur44729 - mac address is out of sync on vpc peers after HSRP flap
Feb 01, 2017
- Cisco Nexus 6000 Series Switches
Known Affected Releases
Symptom: This is a timing issue while sending traffic when issuing the command "clear mac address-table dynamic" simultaneously on vpc peers creates a sync issue where one or more macs may not be deleted on both switches. If traffic restarts on the same macs, then the switches should resync without issue. Conditions: Appears with over 10000 macs in the system, and while traffic is running, and "clear mac address-table dynamic" is used almost simultaneously on both vpc peers. During this period a mac might be deleted, but then gets a new learn notification from the peer, then skips deleting this mac.
