To check traffic on a port

1Determine the port you want to check.

2Type the command. For example:

SYS_console> get-br-cnt 3

====================================================

In this example, a station on port 3 is accessing a server on port 4. To reduce the amount of traffic crossing the switch, connect the server to a hub on port 3 instead of a hub on port 4. This keeps traffic localized to the same segment.

3Repeat steps 1 and 2 for each port on the switch and for each command listed on the previous page.
