Operation Manual – Traffic Accounting
H3C S9500 Series Routing Switches
bases on the internet users' IP addresses and the traffic group which the accessed
network belongs to.
1.1.2 Implementation Process of the Traffic Accounting
The implementation of traffic accounting is shown in
series switches.
Figure 1-1 Implementation process of the traffic accounting
Detailed implementation procedure:
1) The user uses 802.1X or PORTAL authentication client to access to the network.
2) The equipment acquires the user name and password and requests
authentication from CAMS. The equipment and CAMS use the Radius protocol to
communicate.
3) Authentication succeeds. The equipment acquires the IP address and MAC
address for the user to access to the network.
4) The user normally accesses to the network and traffic is generated.
5) The port of the switch collects the traffic and mirrors the traffic to the traffic
accounting board.
6) Traffic accounting board is in charge of the traffic statistics.
7) The main control board collects the user's traffic from the traffic accounting board
periodically.
8) The switch sends the updated message which carries the acquired user's traffic to
CAMS periodically. The traffic is accumulated.
9) The user requests to be offline.
10) The main control board collects the user's traffic for the last time.
11) The switch sends an accounting finish message which carries all the user's traffic
information this time.
12) The user is offline and this process of accessing to the network is over.
