circuitPreferredEP2OptPort

Module: CIRCUIT-MIB

OID (symbolic): CIRCUIT-MIB::circuitPreferredEP2OptPort

OID (numeric): 1.3.6.1.4.1.5812.6.8.1.45

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: If the circuit spans two rings, this is the port number of the second preferred ring.

What is circuitPreferredEP2OptPort?

This sets the port number on the second preferred ring's slot, refining circuitPreferredEP2OptSlot down to a specific physical port, mirroring circuitPreferredEP1OptPort but for the circuit's second ring segment. This matters for the same reason as its EP1 counterpart: a slot can host multiple ring ports, and this field disambiguates exactly which one the admin intends for the second leg of a two-ring circuit. For example, setting this to port 1 while circuitPreferredEP2OptSlot points to slot 9 pins the second ring segment specifically to that slot's first port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.6.8.1.45
snmpwalk -v2c -c public <target> CIRCUIT-MIB::circuitPreferredEP2OptPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.6.8.1.45.1
snmpget -v2c -c public <target> CIRCUIT-MIB::circuitPreferredEP2OptPort.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.6.8.1.45.1 i <value>
