Postcapture Protocol Distribution Tab
208 Sniffer Portable Professional
The Protocol Distribution tab reports network usage based on the
network-, transport-, and application-layer protocols. For example, you
can monitor IPX/SPX, TCP/IP, NetBIOS, AppleTalk, DECnet, SNA,
Banyan, and many other protocols.
Protocol distribution monitors popular IP applications, such as NFS, FTP,
Telnet, SMTP, POP2, POP3, HTTP (WWW), Gopher, NNTP, SNMP,
X-Window, and others. It also monitors IPX transport-layer protocols
such as NCP, SAP, RIP, NetBIOS, Diagnostic, Serialization, NMPI, NLSP,
SNMP, and SPX.
Sniffer Portable Professional also provides an additional 802.11 view
that allows you to view network usage by 802.11 frame types (for
example, Association Requests, Probe Requests, Beacons, and so on).
You can view the protocol distribution in a table, or as a bar or pie chart.
You can also view the number and percentage of packets or bytes for a
protocol.
Sniffer Portable Professional lets you export the protocol distribution
data for tabulation or charting. To export data, the display must be in
the table view.
