dot1agCfmDefaultMdDefMhfCreation

Module: IEEE8021-CFM-MIB

OID (symbolic): IEEE8021-CFM-MIB::dot1agCfmDefaultMdDefMhfCreation

OID (numeric): 1.3.111.2.802.1.1.8.1.2.2

Node type: OBJECT-TYPE

Type: Dot1agCfmMhfCreation

Access: read-write

Description: A value indicating if the Management entity can create MHFs (MIP Half Function) for the VID, for each dot1agCfmDefaultMdEntry whose dot1agCfmDefaultMdMhfCreation object contains the value defMHFdefer. Since, in this variable, there is no encompassing Maintenance Domain, the value defMHFdefer is not allowed.

After this initialization, this object needs to be persistent upon reboot or restart of a device.

What is dot1agCfmDefaultMdDefMhfCreation?

Controls whether the device is allowed to automatically create MIP Half Functions for a VLAN when that VLAN's own setting defers to this default; leaving it at the default 'none' means no auto-creation happens unless configured elsewhere.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.8.1.2.2
snmpwalk -v2c -c public <target> IEEE8021-CFM-MIB::dot1agCfmDefaultMdDefMhfCreation

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.8.1.2.2.1
snmpget -v2c -c public <target> IEEE8021-CFM-MIB::dot1agCfmDefaultMdDefMhfCreation.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.8.1.2.2.1 s <value>
