Disconnects the specified Telnet session.
Example
BayStack> disconnect telnet session 1

download firmware

Downloads the firmware to the router from a directly attached workstation
running terminal emulation software that supports file downloading.
Note: To use this command, you must connect directly to a console. You
cannot use this command during a Telnet session. For details, refer to
"Connecting to the Router Through the Console Port" on page
Because the router resets after completing this command, you are prompted to
confirm the command. You are also prompted to select the download speed. You
should change the terminal baud rate.
Note: Some terminal emulation programs require you to disconnect and then
reconnect the changed parameters to take effect.
Select the Z-modem protocol to download the firmware and then select (open) the
firmware to begin downloading.
Caution: The download firmware command is intrusive to an active ISDN
connection and disconnects all active profile connections.
download config <filename> from <IPaddr>
Downloads the specified configuration file to the router from a TFTP server with
the specified IP address. Use this command to restore a backed up system
configuration.
