Configuring Ingress Pe Router—P Facing Interface - Cisco 7604 Configuration Manual

Configuring Short Pipe Mode
For MPLS and VPN, the ingress PE supports all ingress PFC3BXL or PFC3B IP policies. For
information about the classification for PFC IP policies based on IP ACL/DSCP/precedence, see
http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SXF/configuration/guide/qos.html.
To configure a policy map to set the MPLS EXP field in the imposed label entries, perform this task:
Command
Step 1
Router(config)# mls qos
Step 2
Router(config)# access-list
ipv4_acl_number_or_name permit any
Step 3
Router(config)# class-map class_name
Step 4
Router(config-cmap)# match access-group
ipv4_acl_number_or_name
Step 5
Router(config)# policy-map policy_map_name
Step 6
Router(config-pmap)# class class_name
Step 7
Router(config-pmap-c)# police bits_per_second
[ normal_burst_bytes ] conform-action
set-mpls-exp-transmit exp_value exceed-action
drop
Step 8
Router(config)# interface type slot/port
Step 9
Router(config-if)# no mls qos trust
Step 10
Router(config-if)# service-policy input
policy_map_name
Configuration Example
This example shows how to configure a policy map to set the MPLS EXP field in the imposed label
entries:
Router(config)# mls qos
Router(config)# access-list 1 permit any
Router(config)# class-map CUSTOMER-A
Router(config-cmap)# match access-group 1
Router(config)# policy-map set-MPLS-PHB
Router(config-pmap)# class CUSTOMER-A
Router(config-pmap-c)# police 50000000 conform-action set-mpls-exp-transmit 4
exceed-action drop
Router(config)# interface GE-WAN 3/1
Router(config-if)# no mls qos trust
Router(config)# interface GE-WAN 3/1.31
Router(config-if)# service-policy input set-MPLS-PHB
Configuring Ingress PE Router—P Facing Interface
This procedure classifies packets based on their MPLS EXP field and provides appropriate discard and
scheduling treatments.

Purpose
Enables QoS functionality.
Creates an IPv4 access list.
Creates a class map.
Configures the class map to filter with the ACL created in
step 2.
Creates a named QoS policy.
Configures the policy to use the class map created in step 3.
Configures policing, including the following:
Action to take on packets that conform to the rate limit
•
specified in the service level agreement (SLA).
Action to take on packets that exceed the rate limit
•
specified in the SLA.
The exp_value sets the MPLS EXP field.
Selects an interface to configure.
Configures the interface as untrusted.
Attaches the policy map created in step
an input service policy.
