Information

 
TitleRemote mirroring tag is not added for software forwarded packets in stack
Symptoms
Remote mirroring tag is not added for software forwarded packets in stack. This can cause traffic loss due to MAC move situation caused by packets mirrored with original tag instead of remote-mirrored tag.
Environment
  • SummitStack
  • EXOS 15.6.4.2
Cause
This is cause by a software issue and can be tracked via CR#xos0065157.
Remote-tag is not getting added for Slow-path forwarded packets. This causes the remote-mirrored packets to be treated as packets belonging to a different VLAN and thereby causing MAC moves & data loss. 
Resolution
Upgrade to EXOS where CR#xos0065157 is fixed.
 
Additional notes
This issue only happens on SummitStack.
