Chapter 6 Policing Traffic
AToM Set FR DE as Police Action
The Set ATM CLP Bit Using a Policer feature polices the traffic on the inbound interface of the provider
edge (PE) router where the attachment VC terminates. Marking of the ATM cells using the
set-clp-transmit policing action occurs on the outbound interface. Therefore, when configuring this
feature for AToM, you must attach a policy map that includes the set-clp-transmit action to the interface
upon which the ATM VC terminates or, in other words, attach the policy map to the input interface of
the PE.
The router supports the set-clp-transmit policing action in single-rate and dual-rate policing policies, and
in hierarchical policies.
The router allows you to simultaneously configure the policing actions set-clp-transmit and
set-mpls-exp-imposition-transmit in a single
police
command on the Layer 2 VPN inbound interface.
Feature History for Set ATM CLP Bit Marking As a Police Action
AToM Set FR DE as Police Action
The AToM Set FR DE as Police Action feature enables you to police and mark inbound Frame Relay
traffic before forwarding it onto Any Transport over MPLS (AToM) Layer 2 virtual private network
(VPN) pseudowire. Using this feature, you can configure the
police
command to set the Frame Relay
discard eligibility (DE) bit in the packet header. This bit indicates the drop priority of the frame. During
Frame Relay network congestion, the router discards frames with the DE bit set to 1 before discarding
frames with a DE bit setting of 0.
The AToM Set FR DE as Police Action feature polices the traffic on the inbound interface of the provider
edge (PE) router where the attachment VC terminates. Marking of frames using the set-frde-transmit
policing action occurs on the outbound interface. Therefore, when configuring this feature, you must
attach a policy map that includes the set-frde-transmit action to an input interface of the PE.
The router supports the set-frde-transmit policing action in single-rate and dual-rate policing policies,
and in hierarchical policies.
The router allows you to configure the set-frde-transmit and set-mpls-exp-imposition-transmit policing
actions in a single
police
command on Any Transport over MPLS (AToM) Layer 2 VPN inbound
interfaces.
