CISCO-VIRTUAL-INTERFACE-MIB

AI MIB Summary

The CISCO-VIRTUAL-INTERFACE-MIB enables programmatic creation, deletion, and binding of Cisco virtual interfaces and Virtual Interface Groups to physical ports or EtherChannels. It provides management access to the `cvifGroupTable` for systems supporting interface grouping and exposes operational status for virtual interfaces bound to underlying physical or logical transport layers.

The MIB module for creation and deletion of Virtual Interfaces and Virtual Interface Groups. In addition to this MIB, interface mib (rfc2863) will also contain entries for virtual interfaces. There are two ways virtual interfaces can be created and bound to an interface. The MIB Object cvifGroupsSupported indicates if a particular system supports the Virtual Interface Group concept. If Virtual Interface Groups are supported, then a virtual interface is always created/deleted in conjunction with its associated Virtual Interface Group. The Virtual Interface Group, which may be associated to multiple virtual interfaces, is then bound to a physical interface or another virtual interface like an EtherChannel. If Virtual Interface Groups are not supported, then a virtual interface is created/deleted independently. And each virtual interface is bound to a physical interface or another virtual interface like an EtherChannel. In order for a virtual interface to become operational, it must be directly or indirectly (via its Virtual Interface Group) bound to a physical interface or possibly to another virtual interface such as an EtherChannel. The cvifGroupTable is only used if the MIB object cvifGroupsSupported indicates Virtual Interface Groups are supported.

ciscoVirtualInterfaceMIBThe MIB module for creation and deletion of Virtual Interfaces and Virtual Interface Groups. In addition to this MIB, interface mib (rfc2863) will also contain entries for virtual interfaces. There are two ways virtual interfaces can be created and bound to an interface. The MIB Object cvifGroupsSupported indicates if a particular system supports the Virtual Interface Group concept. If Virtual Interface Groups are supported, then a virtual interface is always created/deleted in conjunction with its associated Virtual Interface Group. The Virtual Interface Group, which may be associated to multiple virtual interfaces, is then bound to a physical interface or another virtual interface like an EtherChannel.

The cvifGroupTable is only used if the MIB object cvifGroupsSupported indicates Virtual Interface Groups are supported.

cvifGroupsSupportedThis is a boolean that indicates whether Virtual Interface Groups are supported (and enabled). Note that many agents are unlikely to support write-access for this object. If there are entries in the cvifGroupTable when this value is being set to false, the set will fail.rw

cvifGroupTableThis table facilitates the creation and deletion of a Virtual Interface Group. Entries in this table exist only if cvifGroupsSupported is 'true'. A Virtual Interface Group is a collection of virtual interfaces on an adapter in a server. The virtual interfaces within a Virtual Interface Group do not need to all have the same ifType.
SEQUENCE OF CvifGroupEntry
.1.3.6.1.4.1.9.9.648.1.2.1
cvifGroupEntryThere is one entry in this table for each created Virtual Interface Group.

cvifGroupIndexAn index that uniquely identifies an entry in the cvifGroupTable table.

cvifGroupBindingIfIndexThe ifIndex of the physical interface or another virtual interface like an Etherchannel bound to this Virtual Interface Group. The binding can happen at Virtual Interface Group creation time or at a later time. In order for Virtual Interface Group to become operational, binding to a physical interface or a virtual interface like an Etherchannel is mandatory. When the virtual interface group is not bound to an interface, this field has a value of zero.rw

cvifTableThis table facilitates the creation and deletion of virtual interfaces. Virtual interfaces may or may not be associated with a Virtual Interface Group according to the value of cvifGroupsSupported. In order for a virtual interface to become operational, it must be directly bound to a physical interface or another virtual interface like an EtherChannel or indirectly bound via its Virtual Interface Group. At creation time, the cvifType must be identified.

cvifTypeThe type of virtual interface desired by the network manager. If and when a row is created in this table by using a SetRequest to cvifRowStatus, the corresponding ifTable row will be created by the agent with its ifType as specified by this object. Note that agents are unlikely to support more than a few values for this object, e.g., 'ethernetCsmacd(6)' and 'fibreChannel(56)'.

It identifies the ifIndex of the interface that this virtual interface is bound to.
