71.3 Classifier Commands
Use these commands to classify packets into traffic flows. After classifying traffic,
policy
commands
( Chapter 73 on page 517 ) can be used to ensure that a traffic flow gets the requested treatment in the
network.
The following table shows some other common Ethernet types and the corresponding protocol number.

Configures a classifier. Specify the parameters to
identify the traffic flow:
ethernet-type
- enter one of the Ethernet
types or type the hexadecimal number that
identifies an Ethernet type (see
Table 259 on
page 510 )
ip-protocol
: enter one of the protocols or type
the port number that identifies the protocol (see
Table 260 on page 511 )
establish-only
: enter this to identify only TCP
packets used to establish TCP connections.
source-socket
: (for UDP or TCP protocols only)
specify the protocol port number.
destination-socket
: (for UDP or TCP protocols
only) specify the protocol port number.
inactive
: disables this classifier.
ipv6-next-header
: enter an 8-bit next header
in the IPv6 packet. The Next Header field is
similar to the IPv4 Protocol field. The IPv6
protocol number ranges from 1 to 255 (see
Table
261 on page 511 ).
See Chapter 55 on page 424 for more
information about IPv6.
C 13

Deletes the classifier.
If you delete a classifier you cannot use policy
rule related information.
C 13
no classifier < name > inactive
Enables a classifier. C 13
