Hi Brian,Howdo I switch between devices when using a Cisco access server?
Thereare two ways to connect to devices attached to an access server, you can terminate your exec session on the access server itself (one terminal window for all sessions), or you can terminate your exec session on the device connected to the access server (one terminal window for each session). In the CCIE Lab Exam you will have the option to do either, so pick whichever method works best for you and stick with it during your preparation.
Whenyou terminate your exec session on the access server you then “reverse telnet” to the individual devices connected to the access server. Normally to do this you first login to the access server and then issue the “show hosts” command to see the host mappings. Next, reverse telnet to them by typing the hostname and pressing enter. To get back to the access server issue the escape sequence CTRL-SHIFT-6-X. To do so hold ctrl and shift, hit 6, release all keys, then hit X. From the access server you can then open new connections or resume connections that you already have open.
Whenyou terminate your exec session on the device connected to the access server, i.e. by telnetting to the access server at port 2001, you cannot issue the escape sequence to reconnect to the access server. In this situation you would open multiple terminal windows if you wanted to connect to multiple devices.
