The traffic accounting module mentioned in this chapter refers to LS81VSNP I/O
Module (line processing unit).
Some accounting servers, such as CAMS, can perform accounting for successfully
authenticated 802.1x users based on time or traffic. Traffic accounting enables the
switch where the users are authenticated to account for the traffic generated
when the users are online and send traffic accounting results to the accounting
server to charge the online users.
Traffic group: a mechanism used to classify destination networks by accounting
■
attributes. The accounting attributes of a traffic group include whether or not
to charge and the charge rate.
Traffic group accounting address: a network IP address configured for a traffic
■
group. You can configure some network addresses for a traffic group, and then
traffic generated by accessing these addresses will be accounted.
Traffic collection module: an interface module configured to perform traffic
■
collection. A traffic collection module sends all the traffic passing through it to
the traffic accounting module.
Traffic accounting module: the module which performs traffic analysis,
■
calculation and statistics.
Traffic collection: the process of sending the traffic passing through the traffic
■
collection module to the traffic accounting module.
Traffic accounting: the process that the traffic accounting module follows to
■
analyze and calculate the traffic obtained from the traffic collection module.
Traffic accounting is performed based on the users' online IP addresses and the
traffic groups to which the accessed networks belong.
Figure 139 shows the implementation process of traffic accounting on the 3Com
Switch 7750s.
