Table 1: show protection-group ethernet-ring node-state Output Fields

Field Name

Field Description

Ring Name/Ethernet Ring

Name configured for the Ethernet ring.

APS State

State of the Ethernet ring APS.

  • idle—Indicates that the ring is working in normal condition and there is no active or pending protection-switching request in the ring. When the ring is in idle state, it is blocked at the RPL link.

  • protected—Indicates that there is a protection switch on the ring because of a signal failure condition on the ring link.

  • MS—Indicates that the manual switch command is active in the ring.

  • FS—Indicates that the forced switch command is active in the ring.

  • pending—Indicates that the ring is in pending state.

Event

Events on the ring.

  • NR-RB—Indicates that there is no APS request and the ring link is blocked on the ring owner node.

  • NR—Indicates that there is no APS request pending in the ring.

  • local SF—Indicates that there is signal failure on one or both of the ring links of the node.

  • remote SF—Indicates that there is signal failure on one or more ring links of any other node of the ring.

  • local FS—Indicates that there is a forced switched command active on one or both of the ring links of the node.

  • remote FS—Indicates that there is a forced switch command active on one or more ring links of any other node of the ring.

  • local MS—Indicates that there is a manual switch command active on one of the ring links of the node.

  • remote MS—Indicates that there is a manual switch command active on one or more ring links of any other node of the ring.

  • WTR running—Indicates that the wait to restore timer is running on the RPL owner.

  • WTB running—Indicates that the wait to block timer is running on the RPL owner.

RPL Owner / Ring Protection Link Owner

Whether this node is the ring owner: Yes or No.

WTR Timer / Restore Timer

Restoration timer: running or disabled.

WTB Timer / Wait to block timer

Wait to block timer: running or disabled.

Note:

The Wait To Block Timer (WTB) is always disabled on EX2300 and EX3400 switches because it is not supported in ERPSv1. Any configuration you make to the WTB setting has no effect. The output from the CLI command 'show protection-group ethernet-ring node-state detail' lists a WTB setting but that setting has no effect.

Wait to block timer (WTB Timer)

Wait to block interval.

Note:

The Wait To Block Timer (WTB) is always disabled on EX2300 and EX3400 switches because it is not supported in ERPSv1. Any configuration you make to the WTB setting has no effect. The output from the CLI command 'show protection-group ethernet-ring node-state detail' lists a WTB setting but that setting has no effect.

Guard Timer

Guard timer: running or disabled.

Op State / Operational State

State of the node: Operational or any internal wait state..
