Output Fields

Table 1 lists the output fields for the show protection-group ethernet-ring aps command. Output fields are listed in the approximate order in which they appear.

Table 1: show protection-group ethernet-ring aps Output Fields

Field Name

Field Description

Ethernet Ring

Name configured for the Ethernet ring.

Request/State

Status of the Ethernet ring RAPS messages.

  • NR—Indicates that there is no request for APS on the ring.

  • SF—Indicates that there is a signal failure on the ring.

  • FS—Indicates that there are active forced-switch requests in the ring.

  • MS—Indicates that there are active manual-switch requests in the ring.

Note:

Both FS and MS values are valid only when G.8032v2 is supported.

Ring Protection Link Blocked

Blocking on the ring protection link: Yes or No.

No Flush

Indicates the value of the Do Not Flush (DNF) flag in the received RAPS PDU. If the value is Yes, then FDB flush is not triggered as part of processing of the received RAPS PDU.

Blocked Port Reference

This parameter is the reference to the blocked ring port. If the east ring port is blocked, the Blocked Port Reference (BPR) value is 0. If the west ring port is blocked, the BPR value is 1. If both ring ports are blocked, this parameter can take any value. If both east and west ports are blocked or not blocked, the value would be 0. This field is valid only when G.8032v2 is supported.

Blocked Port Reference

Reference of the ring port on which traffic is blocked.

Originator

Indicates whether the node is the originator of the RAPS messages.

Remote Node ID

Identifier (in MAC address format) of the remote node.
