The SNAP header includes the Organizational Unit Identifier (OUI) and the
protocol type (see “SNAP Filters” on page 88).

The listboxes in the Protocol Filters option show the protocol filters already set in
the configuration database. Selecting a protocol name and then opening the “Config-

that protocol.
