Access: read-only

Description: Ethernet port to be used on source shelf for the first hop from the source SCM.

What is cmTrunkTopoInterface?

This read-only CmObjectPII identifies the Ethernet port on the source shelf used for the first hop of this topology path. An admin uses it to know exactly which physical port to inspect first when a path is showing connectivity trouble. For example, an admin sees cmTrunkTopoInterface pointing to port 2 on the source shelf and checks that port's link LEDs first.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1996.20.18.3.1.3
snmpwalk -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmTrunkTopoInterface

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1996.20.18.3.1.3.1
snmpget -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmTrunkTopoInterface.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cmTrunkTopoInterface.1
