LABEL DESCRIPTION
Match
Order Select manual to have classifier rules applied according to the weight of each rule you configured in
Advanced Application > Classifier > Classifier Configuration .
Alternatively, select auto 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 classifier 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.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these changes if it
is turned off or loses power, so use the Save link on the top navigation panel to save your changes to
the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
