Displaying Configured Snoop Filters
To display the snoop filters configured on the WX switch, use the
following command:
display snoop info [filter-name]
The following command shows the snoop filters configured in the
examples above:
WX1200# display snoop info
observer snap-length 100
all packets
observer snap-length 100
frame-type eq data
mac-pair (aa:bb:cc:dd:ee:ff, 11:22:33:44:55:66)
Editing a Snoop Filter
To edit a snoop filter, you can use the display configuration area
snoop command to display the filter’s configuration command, then use
cut-and-paste to reconstruct the command.
Deleting a Snoop Filter
To delete a snoop filter, use the following command:
clear snoop filter-name
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.)
