nbsEfmOamMode

Module: NBS-EFM-MIB

OID (symbolic): NBS-EFM-MIB::nbsEfmOamMode

OID (numeric): 1.3.6.1.4.1.629.300.1.3.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: A GET operation returns the current mode of the OAM sublayer entity (see 57.2.6), either passive or active. A SET operation changes the mode of operation of the OAM entity to the indicated value. A SET operation shall have no effect on a device whose mode cannot be changed through management or that can only operate in a single mode.

What is nbsEfmOamMode?

This OID reports and can set the operating mode of the OAM sublayer per IEEE 802.3ah 57.2.6, as notSupported, passive, or active; a set has no effect on a device whose mode is fixed. An admin sets this to active to allow the local device to initiate OAM discovery and remote loopback rather than only responding.
