Table 1: show protection-group ethernet-ring data-channel Output Fields

Field Name

Field Description

Interface

Name of the interface configured for the Ethernet ring.

STP index

The Spanning Tree Protocol (STP) index number used by each interface in an Ethernet ring. The STP index controls the forwarding behavior for a set of VLANs on a data channel on an Ethernet ring port. For multiple Ethernet ring instances on an physical ring port, there are multiple STP index numbers. Different ring instances will have different STP index numbers and may have different forwarding behavior.

Forward State

Forwarding state on the Ethernet ring.

  • fowarding—Indicates packets are being forwarded.

  • discarding—Indicates packets are being discarded.
