Module: CISCO-VIRTUAL-NIC-MIB
OID (symbolic): CISCO-VIRTUAL-NIC-MIB::cvnVethHostID
OID (numeric): 1.3.6.1.4.1.9.9.710.1.1.1.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: A unique identifier, assigned by the system, of the registered VEM.
A VEM is registered and host a virtual ethernet interface when a Virtual Machine attaches to such VEM by using virtual ethernet interface.
A unique identifier, logical module number, is assigned for every VEM.
This object contains value of zero if VEM is directly attached to the switch.
What is cvnVethHostID?
This is a system-assigned identifier for the VEM, or Virtual Ethernet Module, hosting the VM behind a virtual ethernet interface, or zero if the VEM is directly attached to the switch. An admin cares because this pinpoints exactly which physical module in the switching fabric is currently hosting a given VM's traffic. For example, a value of zero here would tell an admin the VEM in question is directly attached rather than reached through an intermediate module, changing where they'd look for a connectivity issue.
