Class-Map Configuration Mode Commands

Class-Map is used to configure a packet classifier for the flow-based Traffic Policing feature within destination context. It filters egress and/or ingress packets of a subscriber session based on rules configured in a subscriber context.

Mode

Exec > Global Configuration > Context Configuration > Class-Map Configuration

configure > context context_name > class-map class_map_name

Entering the above command sequence results in the following prompt:

Syntax

match ip-tos { service_value [ ip-tos-mask mask_value ] | tos-range low_value to high_value }

service_value

Specifies the IP Type-of-Service value to match inside the ToS field of packets as an integer from 0 to 255.

ip-tos-mask mask_value

Specifies the IP Type-of-Service mask value to match inside the ToS field of packets as an integer from 1 to 255.

tos-range low_value to high_value

Specifies a range that a ToS value in a received packet must fall within to be considered a match. low_value and high_value must be an integer from 0 to 255.

Usage Guidelines

Sets the match rule based on the IP ToS value in ToS field of packets for specific Class Map.

Example

The following commands specifies the IP ToS value of 3 is the value to match in a ToS field in received packets. 
match ip-tos 3

index_value

Specifies the IPSec SPI value to match inside the SPI field of packets as an integer from 1 to 65535.

Usage Guidelines

Sets the match rule based on the IPSec SPI value in SPI field of packets for specific Class Map.

Example

Syntax

match packet-size [ gt | lt ]  size

[ gt | lt ] size

Specifies the packet length in bytes.

gt : indicates a packet size greater than the specified size.

lt : indicates a packet size less than the specified size.

size must be an integer from 1 to 65535.

Usage Guidelines

Sets the match rule based on the size of packets for specific Class Map. This command is only applicable for static policies; it is not available for dynamic policies.

Example

The following command specifies the packet length to be 1024 bytes. 
match packet-size 1024

gre

Sets the match rule for session flow using Generic Routing Encapsulation (GRE) Protocol. It matches the protocol field to GRE inside the packet.

ip-in-ip

Sets the match rule for session flow using IP-in-IP encapsulation protocol. It matches the protocol field to ip-in-ip inside the packet.

number

Sets the match rule for a session flow using Transmission Control Protocol (TCP). It matches the specified protocol field inside the packet.

rtp
