ol52nnMFRTrunkExtBcnRecovery

Module: CHIPCOMMIB

OID (symbolic): CHIPCOMMIB::ol52nnMFRTrunkExtBcnRecovery

OID (numeric): 1.3.6.1.4.1.49.2.3.1.4.4.20.3.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Indicates whether the trunk is connected to a

segment that will perform beacon recovery. This

should be set to exists(1) for trunks which connect

to hubs which perform beacon recovery. This attribute

is used to determine the fault domain when resolving a

beaconing condition.

The beacon recovery process will resolve beaconing on

trunks with this attribute set to nonExists(2) before

trunks with the attribute set to exists(1) are resolved.

For backplane trunks, setting to a value other than

notApplicable will return invalidData error. The

default value is nonExists(2).

What is ol52nnMFRTrunkExtBcnRecovery?

This read-write object indicates whether the trunk is connected to a segment capable of beacon recovery, and should be set to 'exists' for trunks linked to hubs that perform beacon recovery; it helps determine the fault domain when resolving a token ring beaconing condition.
