ok...the switch is now called passport model
the documentation is not sufficient to read thru..
1. try to find open ports on the switch which are listening to traffic.
default port may not be the telnet port.
2. put a software sniffer on the netowrk to see what the switch is doing..
3. does it have connectivity thru serial port??? if yes, get a null modem cable and hook it up...use hyperterminal to see if it shows any sign for configuration
