Known Affected Releases


Description (partial)

No traffic for some vEths after reboot of HOST ( including VSM, VSE and user VMs ) and then comes online.

On VSM logs similar to following would appear for affected vEths -

"VEM_MGR-SLOT5-1-VEM_SYSLOG_ALERT: L2 TABLE : Packet with Source MAC address 0050:56b4:aab5 received on ltl: 55 is program as Static entry for ltl 53"

Reboot of HOST ( including VSM, VSE and user VMs ) and then powered on back.  The network adapters would have mapped to old IPGs which doesn't have IPG mappings on Nexus1000V.  So, the traffic would get affected.
