dot1agCfmDefaultMdDefLevel
Module: IEEE8021-CFM-MIB
OID (symbolic): IEEE8021-CFM-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?
The default Maintenance Domain Level at which the device auto-creates MIP Half Functions (MHFs) for any per-VLAN entry that leaves its own level unset (-1); an admin tunes this to control fault-monitoring granularity network-wide, and the value must persist across reboots.
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-CFM-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-CFM-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>
