Description: An entry in this table exists for each ifEntry that represents a component link. An ifEntry must exist in the ifTable before a componentLinkEntry is created with the corresponding ifIndex. ifEntry's ifType can be of any interface type that has been defined for TE Link interworking. Examples include ATM, Frame Relay, Ethernet, etc. If an entry representing a component link is destroyed in the ifTable, then so is the corresponding entry in the componentLinkTable. The administrative and operational status values are controlled from the ifEntry.
