This command requir es 2.1 or higher so ft ware.
No limit exists on the number of telnet hops you can take from an individual CLI session. However, an
individual node has a limit of 15 telnet sessions. Therefore, a limit of 15 users can start telnet sessions.

the telnet attempt if the des t in ati on n o de is unable to accept the tel ne t session for
reasons such as: the destination switch is down or unreachable; its in backup boot
mode; or it detects that TCP communication is down. If you use the escape sequence,
