nbsRedundCfgPreferredAdmin
Module: NBS-REDUNDANCY-MIB
OID (symbolic): NBS-REDUNDANCY-MIB::nbsRedundCfgPreferredAdmin
OID (numeric): 1.3.6.1.4.1.629.221.1.2.1.20
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Persistent. Used to optionally indicate one port in a redundant pair should always be active if it has ifOperStatus up(1). Equivalent/aliased to nbsCmmcPortPreferred.
Setting one port to preferActive(3) forces its redundant partner to preferNot(2).
Setting a port to preferNot(2) has no effect on its redundant partner.
What is nbsRedundCfgPreferredAdmin?
This persistent object indicates whether a port in a redundant pair should always become active whenever it's operationally up, with values notSupported, preferNot, or preferActive; setting one port to preferActive(3) automatically forces its partner to preferNot(2). An admin sets this on the port they want to serve as the primary link whenever both ports are healthy, such as a newer, higher-bandwidth uplink over an older backup. Setting a port to preferNot(2) directly has no side effect on its partner, unlike setting preferActive(3).
