cmTrunkIfAdminState

Module: COPPER-MOUNTAIN-NETWORKS-DSL-MIB

OID (symbolic): COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmTrunkIfAdminState

OID (numeric): 1.3.6.1.4.1.1996.20.18.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This allows the operator to enable and disable a particular ethernet port. The operational state of the port can be determined by accessing the cmTrunkIfOperState object.

What is cmTrunkIfAdminState?

This read-write INTEGER lets an operator administratively enable or disable a particular Ethernet trunk port on an SCM shelf-control module. An admin uses it to intentionally take an inter-shelf trunk port out of service for maintenance without disturbing cabling, then checks cmTrunkIfOperState to confirm the port actually went down. For example, a technician sets this object to disable(1) on SCM1's trunk port before swapping a suspect cable, then re-enables it once the swap is done.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1996.20.18.1.1.3
snmpwalk -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmTrunkIfAdminState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1996.20.18.1.1.3.1
snmpget -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmTrunkIfAdminState.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1996.20.18.1.1.3.1 i <value>
