Module: CISCO-VIRTUAL-NIC-MIB
OID (symbolic): CISCO-VIRTUAL-NIC-MIB::cvnConnecteeAttachType
OID (numeric): 1.3.6.1.4.1.9.9.710.1.2.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object indicates how virtual ethernet interface is attached to this system.
none - virtual ethernet interface is not participating.
vem - Always a dynamic attachment. For this type of attachment switching is done by host at software layer.
niv - A fixed or dynamic attachment. For this type of attachment switching is done in asics
What is cvnConnecteeAttachType?
This indicates how a virtual ethernet interface is attached to the system: not participating, dynamically via a VEM doing software-based switching on the host, or via NIV, a fixed or dynamic attachment switched in hardware. An admin cares because this determines whether switching for that VM's traffic happens in host software or in switch hardware, which affects performance expectations and troubleshooting approach. For example, a VM showing niv(3) has its traffic switched in the adjacent switch's ASICs, so packet-forwarding issues should be investigated there rather than on the host.
