Snoop Commands 577

set snoop

Configures a snoop filter.

Syntax set snoop filter-name [condition-list] [observer ip-addr][snap-lengthnum]

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-pairmac-addr1 mac-addr2
	To match on packets to or from a specific MAC address, use the dest-mac
	or src-macoption. To match on both send and receive traffic for a host
	address, use the host-macoption. To match on a traffic flow (source and
	destination MAC addresses), use the mac-pairoption. 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-macconditions also support lt (less
	than) and gt (greater than).
observer ip-addr	Specifies the IP address of the station where the protocol analyzer is
	located. If you do not specify an observer, the AP radio still counts the
	packets that match the filter.
snap-length num	Specifies the maximum number of bytes to capture. If you do not specify
	a length, the entire packet is copied and sent to the observer. Nortel
	recommends specifying a snap length of 100 bytes or less.

Defaults No snoop filters are configured by default.
