HP Manager Software manual Chapter Snoop Commands

572CHAPTER : SNOOP COMMANDS

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.

„observer ip-addr— Specifies the IP address of the station where the protocol analyzer is located. If you do not specify an observer, the MAP radio still counts the packets that match the filter.

„snap-lengthnum — 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. 3Com recommends specifying a snap length of 100 bytes or less.

Defaults — No snoop filters are configured by default.

Access — Enabled.

History —Introduced in MSS Version 4.0.

Usage — Traffic that matches a snoop filter is copied after it is decrypted. The decrypted (clear) version is sent to the observer.

For best results:

„Do not specify an observer that is associated with the MAP where the snoop filter is running. This configuration causes an endless cycle of snoop traffic.
