pportAPSlineType

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::pportAPSlineType

OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.130

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: APS line type for the pport. Writable only when pportRedundancyArch is disabled.

What is pportAPSlineType?

This designates whether this port serves as the working line or the protection line in an APS pair, but per the description it is only writable when pportRedundancyArch is set to disabled. Because it is locked once a redundancy architecture is active on this specific port, this setting is really configured during initial APS setup before enabling the architecture, rather than something adjusted on the fly during live protection operation. An admin setting up a new 1+1 APS pair would set this port's pportAPSlineType to protection-line while pportRedundancyArch is still disabled, then only afterward enable the chosen architecture.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.130
snmpwalk -v2c -c public <target> CASCADE-MIB::pportAPSlineType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.130.1
snmpget -v2c -c public <target> CASCADE-MIB::pportAPSlineType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.130.1 i <value>
