Configuring Protocol Classification

For Layer 3 protocol traffic, you can use the ACL classification match. For more information, see the
"Configuring ACL Classification" section.
You can classify traffic based on the protocol arguments described in the table below.
Table 13: match Command Protocol Arguments
Argument
arp
bridging
cdp
clns
clns_es
clns_is
dhcp
isis
ldp
netbios
A maximum of eight different protocols (in the table above) can be matched at a time.

Configuring Protocol Classification
Description
Address Resolution Protocol (ARP)
Bridging
Cisco Discovery Protocol (CDP)
Connectionless Network Service (CLNS)
CLNS End Systems
CLNS Intermediate System
Dynamic Host Configuration (DHCP)
Intermediate system to intermediate system (IS-IS)
Label Distribution Protocol (LDP)
NetBIOS Extended User Interface (NetBEUI)
Purpose
Enters global configuration mode.
Creates or accesses the class map named
class-map-name and enters class-map mode.
The class map name can contain alphabetic,
hyphen, or underscore characters, is case
sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets
based on the specified protocol. Use the not
keyword to match on protocols that do not
match the protocol specified.
Exits global class-map queuing mode, and
enters configuration mode.
Saves this configuration change.
