Classifier Control Lists Overview
Classifier control lists (CLACLs) specify the criteria
by which the router defines a packet flow. Table 1 lists the criteria that you can use to create CLACLs for
different types of traffic flows.
Table 1: CLACL Criteria
Type of CLACL | Criteria |
|---|
ATM | - CLP
- Color
- Traffic class
- User packet class
|
Frame Relay | - Color
- Mark discard eligibility (DE) bit
- Traffic class
- User packet class
|
GRE | - Color
- Traffic class
- Type-of-service (ToS) byte
- User packet class
|
IP | - Color
- Destination IP address
- Destination port
- Destination route class
- Internet Control Message Protocol (ICMP)
- Internet Gateway Management Protocol (IGMP)
- IP flags
- IP fragmentation offset
- Locally destined traffic
- Protocol
- Source IP address
- Source port
- Source route class
- Transmission Control Protocol (TCP)
- Traffic class
- Type-of-service (ToS) byte
- User Datagram Protocol (UDP)
- User packet class
|
IPv6 | - Color
- Destination IPv6 address
- Destination port
- Destination route class
- Internet Control Message Protocol version 6 (ICMPv6)
- IPv6 traffic class
- Locally destined traffic
- Multicast Listener Discovery (MLD)
- Next header
- Source IPv6 address
- Source port
- Source route class
- Traffic class
- Transmission Control Protocol (TCP)
- User Datagram Protocol (UDP)
- User packet class
|
L2TP | - Color
- Traffic class
- User packet class
|
MPLS | - Color
- Mark experimental (EXP) bit
- Traffic class
- User packet class
|
VLAN | - Color
- Traffic class
- User packet class
- User priority
|
You configure CLACLs with a name and then values
to match in the IP datagram header. A CLACL does not include an action:
actions take place when a match is included in a policy list.
 | Note:
Do not use the asterisk (*) for the name of a classifier
list. The asterisk is used as a wildcard for the classifier-group command. If you do not specify one of the frame-relay, gre-tunnel, ip, ipv6, l2tp, mpls, or vlan keywords, the router creates an
IP classifier list. This version of the command has been deprecated
and may be removed in a future release. |
