(Forwarding Class Accounting)

(Enhanced CoS Accounting)

Hierarchy Level

Description

Forwarding class accounting (non-enhanced mode) is enabled for IPv4, IPv6, MPLS, Layer 2 and other packets simply by enabling the feature. This feature is supported on MX Series routers with MPCs, as well as MX80 routers.

Note:

Forwarding class accounting (enhanced mode) is not supported in hyper-mode (forwarding-options).

Both bytes and packet total are counted. For Layer 2 traffic, only bytes are counted. Flow rates are measured. Counters can be enabled in ingress, egress or in both directions. Statistics are accounted before queueing drop stage, so will include packets that might get dropped in queueing.

CoS-based interface counters (enhanced mode) are supported for IPv4 and IPv6 aggregate routes on Layer 2. This feature is supported on all MX Series routers with MPCs, as well as MX80 routers.

Both bytes and packet total are counted. Flow rates are not measured. The counters can be configured to exclude overhead bytes (such as protocol encapsulations) so end-customer packets can be differentiated from other traffic.

Disable or delete forwarding-class-accounting by removing the statement from the interface configuration–for example, by typing delete interfaces interface-name forwarding-class-accounting.
