host1(config)#mpls classifier-list be-green traffic-class best-effort color yellow

To map the specified PHB ID to the internal traffic class/color combination:

•

Issue the mpls diff-serv phb-id traffic-class command.

host1(config)#mpls diff-serv phb-id standard 45 traffic-class gold color green

To create or modify an MPLS policy:

•

Issue the mpls policy-list command.

host1(config)#mpls policy-list mpls-exp-setting

To enable collection of policy statistics for a tunnel or LSP. Collection is disabled by

default.

•

Issue the mpls policy-statistics command.

host1#mpls policy-statistics boston2dc

Policy statistics are displayed when you issue the show mpls forwarding or show mpls

tunnel command, if a policy is attached and policy statistics are enabled.

To specify the traffic class for which LSP-level queues are created and the scheduler

profile to be used with the queues:

•

Issue the mpls traffic-class command.

host1(config)#mpls traffic-class af1 scheduler-profile af1-scheduler-profile

These classes originate from E-LSPs and L-LSPs (classes derived from the signaled

PHB-ID) or regular LSPs (classes configured with the mpls traffic-class command)

To specify the PHB supported by a signaled tunnel:

•

Issue the tunnel mpls diff-serv phb-id command.

host1(config-if)#tunnel mpls diff-serv phb-id standard 35 exp-bits 5

For E-LSPs, you also use this command to map the PHB to the specified exp-bits bitValue.

You can repeat the command for up to eight PHB mappings.

For L-LSPs, do not use the exp-bits keyword. If you repeat the command, the most recent

command overwrites the previous command.

Preference of per-VR Versus per-LSP Behavior

MPLS always prefers the per-LSP method of matching and setting EXP bits by means

of applied policies over the per-VR method.

Per-VR matching of EXP bits is not performed on the LSP when an input policy (matching

on incoming EXP bits) is attached to the ingress segment of the LSP.

Similarly, per-VR setting of EXP bits is not performed on the LSP when an output policy

(setting the outgoing EXP bits) is attached to the egress segment of the LSP.
