Do protocol analyzers use SNMP?
Typically not. SNMP products provide device specific information, where protocol analyzers obtain all their information by examining the traffic on the LAN. For example, an SNMP collection utility could not provide session delta time stamps for a UNIX telnet session, nor can SNMP provide bandwidth utilization statistics directly. Example SNMP statistics would include how many packets came in or went out of a router, a print server’s IP address, or a predefined trap generated by a network printer for “out of paper”. SNMP products are a good complement to any protocol analyzer.
