set snoop
Configures a snoop filter.
Syntax set snoop filter-name [condition-list] [observer ip-addr] [snap-length num]
filter-name Name of the snoop filter.
ap apnum Number of an MP to which to snoop filter is mapped.
radio 1 Radio 1 of the MP.
radio 2 Radio 2 of the MP. (This option does not apply to single-radio models.)
filter-name Name for the filter. The name can be up to 15 alphanumeric characters, with no
spaces.
condition-list Match criteria for packets. Conditions in the list are ANDed. Therefore, to be copied
and sent to an observer, a packet must match all criteria in the condition-list. You can
specify up to eight of the following conditions in a filter, in any order or combination:
❑ frame-type {eq | neq} {beacon | control | data | management | probe}
❑ channel {eq | neq} channel
❑ bssid {eq | neq} bssid
❑ src-mac {eq | neq | lt | gt} mac-addr
❑ dest-mac {eq | neq | lt | gt} mac-addr
❑ host-mac {eq | neq | lt | gt} mac-addr
❑ mac-pair mac-addr1 mac-addr2
❑ direction {eq | neq} {transmit | receive}
To match on packets to or from a specific MAC address, use the dest-mac or src-mac
option. To match on both send and receive traffic for a host address, use the host-mac
option. To match on a traffic flow (source and destination MAC addresses), use the
mac-pair option. This option matches for either direction of a flow, and either MAC
address can be the source or destination address.
If you omit a condition, all packets match that condition. For example, if you omit
frame-type, all frame types match the filter.
For most conditions, you can use eq (equal) to match only on traffic that matches the
condition value. Use neq (not equal) to match only on traffic that is not equal to the
condition value.
The src-mac, dest-mac, and host-mac conditions also support lt (less than) and gt
(greater than).
