cwspLoadAvlVcUbr

Module: CISCO-WAN-SVC-MIB

OID (symbolic): CISCO-WAN-SVC-MIB::cwspLoadAvlVcUbr

OID (numeric): 1.3.6.1.4.1.351.140.1.2.13.1.1.18

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The number of VCs used by UBR service.

What is cwspLoadAvlVcUbr?

This read-only Integer32 (0..2147483647), despite its name, is documented as reporting the number of VCs currently used by UBR (Unspecified Bit Rate) service on the interface, i.e. how many virtual circuits of that class are presently in use. An administrator tracks this to see how the interface's finite VC pool is distributed across service categories, which helps explain why cwspLoadVcAvail is dropping even when overall bandwidth use looks moderate. For example, a spike in cwspLoadAvlVcUbr alongside a falling cwspLoadVcAvail confirms that the growth in active UBR (Unspecified Bit Rate) SVCs, specifically, is what is consuming the interface's remaining VC capacity.
