OAM commands

All VPLS OAM commands may be used in both I-VPLS and B-VPLS instances.

I-VPLS

• The following OAM commands are meaningful only toward another I-VPLS service instance (spoke-SDP in I-VPLS):

  • LSP-ping
  • LSP-trace
  • SDP-MTU

• The following I-VPLS OAM exchanges are transparently transported over the B-VPLS core:

  • SVC-ping
  • MAC-ping
  • MAC-trace
  • MAC-populate
  • MAC-purge
  • CPE-ping (toward customer CPE)
  • 802.3ah EFM
  • SAA

• PBB up links using MPLS/SAP; there are no PBB specific OAM commands.

B-VPLS

In case of Ethernet switching backbone (B-SAPs on B-VPLS), 802.1ag OAM is supported on B-SAP, operating on:

• the customer level (C-SA/C-DA and C-type layer)

• the tunnel level (B-SA/B-DA and B-type layer)
