cvnVethHostAddr
Module: CISCO-VIRTUAL-NIC-MIB
OID (symbolic): CISCO-VIRTUAL-NIC-MIB::cvnVethHostAddr
OID (numeric): 1.3.6.1.4.1.9.9.710.1.1.1.1.6
Node type: OBJECT-TYPE
Type: InetAddress
Access: read-only
Description: The Internet address of the VEM which hosts the VM.
The type of this address is determined by the value of the cvnVethHostAddrType object.
This object also indicates the management address of the VEM. Value of this object may be changed when virtual ethernet interface moves from one VEM to another VEM.
What is cvnVethHostAddr?
This is the actual management address of the VEM currently hosting the VM behind a virtual ethernet interface. An admin cares because this is the address to use to reach or investigate the specific physical host currently serving that VM's traffic, and it changes automatically when the VM migrates. For example, after a VM moves to a different ESX host, this value updates to reflect the new VEM's management address rather than the old one.
Examples
Walk all instances (SNMPv2c):
