Roving Analysis—The Roving Analysis Port (RAP) 
feature allows you to configure the SuperStack II 
Switch 2000 TR to capture and monitor traffic on 
any Token Ring LAN connected to the switch using 
any industry-standard LAN analyzer. 

This feature operates on Port 1 of the Switch 2000 
TR and applies to all ports of the same switch. To 
view traffic on other switches in a stack you must 
connect to Port 1 of the appropriate switch and 
select the port you wish to view.
