Description
This command creates a classifier. A classifier defines a traffic flow. A
traffic flow consists of packets that share one or more characteristics. A
traffic flow can range from being very broad to being very specific. An
example of the former might be all IP traffic while an example of the latter
could be packets with specific source and destination MAC addresses.
You use classifiers with access control lists (ACL) and Quality of Service
policies. The classifiers define the traffic flow to be affected by the ACL or
QoS.
If you create a classifier without any parameters, then all incoming packets
are classified.
Note
For definitions and restrictions on the classifier variables, refer to the
Chapter 13, “Classifiers” in the AT-S63 Management Software
Menus Interface User’s Guide.
Examples
This command creates a classifier for all IP traffic:
create classifier=4 description=”IP flow” protocol=ip
This command creates a classifier for all traffic originating from the subnet
149.22.22.0 destined to the device with the IP address 149.44.44.11:
create classifier=4 description=”subnet flow”
ipsaddr=149.22.22.0/24 ipdaddr=149.44.44.11
This command creates a classifier for all HTTPS web traffic going to the
destination IP address 149.44.44.44:
create classifier=7 description=”HTTPS flow”
ipdaddr=149.44.44.44 tcpdport=443
