The following table describes the labels in this screen.
21.5 C la ssifie r Exa m ple
The following screen shows an example where you configure a classifier that identifies all traffic from
MAC address 00:50:ba:ad:4f:81 on port 2.
After you have configured a classifier, you can configure a policy (in the
Po lic y
screen) to define
action(s) on the classified traffic flow.

Alternatively, select

to have classifier rules applied according to the layer of the item configured
in the rule. Layer-4 items have the highest priority, and layer-2 items has the lowest priority. For
example, you configure a layer-2 item (VLAN ID) in classifier A and configure a layer-3 item (source IP
address) in classifier B. When an incoming packet matches both classifier rules, classifier B has priority
over classifer A.
Logging
Active Select this to allow the Switch to create a log when packets match a classifier rule during a defined
time interval.
Interval Select the length of the time period (in seconds) to count matched packets for a classifier rule. Enter
an integer from 0-65535. 0 means that no logging is done.
