cmFlowMaximumA2NBandwidthLo

Module: CM-FACILITY-MIB

OID (symbolic): CM-FACILITY-MIB::cmFlowMaximumA2NBandwidthLo

OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.4.1.28

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This object supports the Hierarchical Class of Service (HCOS) feature. It is only applicable for a flow with multiple class of services. This allows the provisioning of maximum bandwidth (lower 32 bits) of a flow. This is the peak limit of a flow. This value must be greater than or equal to the sum of all individual COS CIRs.

In case of Tranparent Flow this object represents N1 to N2 and N2 to N1 maximum bandwidth.

What is cmFlowMaximumA2NBandwidthLo?

This read-write Unsigned32, applicable only to multi-COS flows using HCOS and representing the lower 32 bits, sets the peak A2N bandwidth ceiling of the Ethernet Flow, which must be greater than or equal to the sum of all individual COS CIRs. It caps how far the flow's combined COS traffic can burst above its guaranteed level. For example, an administrator sets a maximum A2N bandwidth above the guaranteed level to allow occasional bursting across all COS classes combined, up to a hard peak ceiling.
