dot1agCfmLtrEgressPortId

Module: IEEE802171-CFM-MIB

OID (symbolic): IEEE802171-CFM-MIB::dot1agCfmLtrEgressPortId

OID (numeric): 1.0.8802.1.1.3.1.6.2.1.20

Node type: OBJECT-TYPE

Type: LldpPortId

Access: read-only

Description: Egress Port ID. The format of this object is determined by the value of the dot1agCfmLtrEgressPortIdSubtype object.

What is dot1agCfmLtrEgressPortId?

The port ID on the responding device through which the traced Linktrace Message was (or would be) forwarded out, formatted per dot1agCfmLtrEgressPortIdSubtype. Use this to pinpoint exactly which egress interface on that hop the trace would continue through.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.0.8802.1.1.3.1.6.2.1.20
snmpwalk -v2c -c public <target> IEEE802171-CFM-MIB::dot1agCfmLtrEgressPortId

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.0.8802.1.1.3.1.6.2.1.20.1
snmpget -v2c -c public <target> IEEE802171-CFM-MIB::dot1agCfmLtrEgressPortId.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dot1agCfmLtrEgressPortId.1
