Mapping a Snoop

Filter to a Radio

You can map a snoop filter to a radio on a MAP. To map a snoop filter to
a radio, use the following command:

set snoop map filter-name ap apnumber radio {1 | 2}

You can map the same filter to more than one radio. You can map up to
eight filters to the same radio. If more than one filter has the same
observer, the MAP sends only one copy of a packet that matches a filter
to the observer. After the first match, the MAP sends the packet and
stops comparing the packet against other filters for the same observer.

If the filter does not have an observer, the MAP still maintains a counter
of the number of packets that match the filter. (See “Displaying Remote
Traffic Monitoring Statistics” on page 643.)
