9. Monitoring Port Traffic

The CrossFire 8600 Token-Ring Switch and the CrossFire 8605 Token-Ring Fiber Switch allow you to configure a Switched Port Analyzer function for monitoring traffic on a port by defining a monitor port where an external probe can observe traffic from a selected monitored port. The monitoring function does not interfere in any way with the normal traffic flow in the switch.

The external probe (e.g. a protocol analyzer) is not supplied with the switch.

You can monitor traffic going through a monitored port in two different ways:

Active Monitoring:

Data-only monitoring - you can select the monitored port and monitor port, all data traffic received and transmitted on the monitored port is copied to the monitor port such that it can be received by an external probe. The MAC frames are not copied to the monitor port.

Passive Monitoring:

All traffic monitoring (data and MAC protocol) - makes a copy of all data and MAC frames received and transmitted on the monitored port to up to two monitor ports; you can specify a dedicated monitor port for traffic received on the monitored port and a different monitor port for traffic transmitted on the monitored port. You must use two monitor ports if the monitored port operates in FDX mode.

To configure a Switched Port Analyzer port, select Switched Port Analyzer Configuration on the Configuration menu. The Switched Port Analyzer Configuration screen is then displayed (see the next page).
