Known Affected Releases

4.1.1.BASE

Description (partial)

Symptom:

With g.8032 you can exclude different vlans from being protected or participating.  These tie back to sub interfaces associated to those vlans.  

Example:
l2vpn
 ethernet ring g8032 SubRing22
  port0 interface Bundle-Ether626
  !
  port1 interface Bundle-Ether103
  !
  open-ring
  exclusion-list vlan-ids 1223  <<<<<<<<
  instance 1
   profile RingProfile
   rpl port0 owner
   inclusion-list vlan-ids 1222,1224,210
   aps-channel
    level 0
    port0 interface Bundle-Ether626.210
    port1 interface Bundle-Ether103.210

Conditions:

Even though vlan 1223 is configured as excluded it shows as blocked and can make troubleshooting for the customer confusing. 

Example:
show l2vpn protection main-interface bundle-e103 detail
