CISCO-VIRTUAL-NIC-MIB
AI MIB Summary
The CISCO-VIRTUAL-NIC-MIB enables monitoring and configuration of virtual Ethernet interfaces (veths) and their associated Virtual Network Interface Cards (VNICs) within Cisco's Distributed Virtual Switch (DVS) architecture. It provides operational visibility into the mapping between virtual chassis line cards (Virtual Ethernet Modules) and connected VM instances, tracking connectivity states for VM kernel ports (VMK) and management interfaces (VSWIF) independent of VM migration events.
This MIB module defines MIB objects which provide mechanisms to manage the parameters used by or related to Virtual NIC.
Virtual switch extends across one or more virtualization servers which host the VM instances. Each virtualization server is represented as a line card module and is assigned to a unique slot in the virtual chassis.
All the ports on the virtual switch which can be hooked up to VM VNICs or to special hypervisor ports (e.g. vmk or vswif ports) are represented as virtual ethernet interfaces.
Virtual ethernet interfaces(veths) represent the switching ports on the virtual switch which provide networking connectivity to virtual packet based interfaces such as the Virtual NIC (VNIC) interfaces defined on a Virtual Machine (VM).
These interfaces are configurable and provide operational information to the network administrator.
The assignment of virtual ethernet interface ports to a VM does not change when the VM is migrated.

ciscoVirtualNicMIBThis MIB module defines MIB objects which provide
mechanisms to manage the parameters used by or

Virtual switch extends across one or more
virtualization servers which host the VM instances.

the virtual chassis.
All the ports on the virtual switch which can be
hooked up to VM VNICs or to special hypervisor ports
(e.g. vmk or vswif ports) are represented as virtual

cvnPinningTableA list of virtual ethernet interfaces which supports
pinning functionality in VSM.
Pinning is a mechanism of directing traffic to or
from a interface through a particular interface
in a switch.
By default, system use load balancing algorithm to pick
the best possible physical interface automatically.
However, user may use pinning functionality to
instrument the finite control on the traffic flow
between virtual ethernet interfaces and actual physical
interfaces in VSM.
For example, user may want to configure that packets
from a particular virtual ethernet interface always go
out through first interface in the port channel
irrespective of load balancing policy on the switch.
In order to achieve this, user can pin the virtual
ethernet interface to first interface of the switch. SEQUENCE OF CvnPinningEntry .1.3.6.1.4.1.9.9.710.1.1.2 |
cvnPinningEntryAn entry containing pinning management information
for a particular virtual ethernet interface.
