Chapter 17: Classifier Commands
286 Section II: Advanced Operations
Description
This command modifies an existing classifier. The only setting of a
classifier you cannot change is its ID number.
Specifying a new value for a variable that already has a value overwrites
the current value with the new one. The ANY option removes a variable’s
value without assigning it a new value.
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 the 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
