CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Monitoring Port Traffic
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).
