Chapter 17: Classifier Commands
318 Section II: Advanced Operations
Description
This command is used to modify classifiers. You can change all the
parameters of a classifier except for the ID number.
Specifying a new value for a variable that already has a value overwrites
the current value with the new one. To remove a value from a variable
without assigning a new value, use the ANY option.
You cannot modify a classifier if it belongs to an ACL or QoS policy that is
assigned to a port. You must first remove the port assignments from the
ACL or policy before you can modify it.
Examples
This command adds the destination IP address 149.22.22.22 and the
source subnet IP address 149.44.44.0 to classifier ID 4:
set classifier=4 ipdaddr=149.22.22.22
ipsaddr=149.44.44.0/24
This command adds the Layer 3 protocol IGMP to classifier ID 6:
set classifier=6 ipprotocol=igmp
This command removes the current setting for the UDP destination port
variable from classifier ID 5 without assigning a new value:
set classifier=5 udpdport=any
