usdAtmIfCacAvailableBandwidth

Module: Unisphere-Data-ATM-MIB

OID (symbolic): Unisphere-Data-ATM-MIB::usdAtmIfCacAvailableBandwidth

OID (numeric): 1.3.6.1.4.1.4874.2.2.8.1.1.2.1.18

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The available bandwidth of the ATM major interface. As connections are added or deleted on the interface, this value is updated. The units are kilo-bits per second (kbps).

What is usdAtmIfCacAvailableBandwidth?

Read-only bandwidth, in kbps, still available for new connections on this ATM interface under CAC, updated automatically as circuits are added or removed. Check this before provisioning a new CBR/VBR circuit to confirm there's enough headroom for it to be admitted.

Examples
