dot1agCfmDefaultMdDefLevel

Module: IEEE8021-CFMD8-MIB

OID (symbolic): IEEE8021-CFMD8-MIB::dot1agCfmDefaultMdDefLevel

OID (numeric): 1.3.111.2.802.1.1.8.1.2.1

Node type: OBJECT-TYPE

Type: Dot1agCfmMDLevel

Access: read-write

Description: A value indicating the MD Level at which MHFs are to be created, and Sender ID TLV transmission by those MHFs is to be controlled, for each dot1agCfmDefaultMdEntry whose dot1agCfmDefaultMdLevel object contains the value -1. After this initialization, this object needs to be persistent upon reboot or restart of a device.

What is dot1agCfmDefaultMdDefLevel?

Sets the default 802.1ag Maintenance Domain (MD) level used when auto-creating MIP Half Functions on a VLAN whose own level setting (dot1agCfmDefaultMdLevel) is -1. An admin configures this so newly discovered VLANs get consistent CFM fault-monitoring behavior without needing individual per-VLAN configuration; the setting must survive a reboot.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.8.1.2.1
snmpwalk -v2c -c public <target> IEEE8021-CFMD8-MIB::dot1agCfmDefaultMdDefLevel

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.8.1.2.1.1
snmpget -v2c -c public <target> IEEE8021-CFMD8-MIB::dot1agCfmDefaultMdDefLevel.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.8.1.2.1.1 s <value>
