Hi
I am having similar issues logging on to Extreme's X450 switch using
clogin (ExtremeXOS version 11.6.3.4) as mentioned in the thread "clogin
on extreme X450". However in my case the login process works about 70%
of the time (but has to make two attempts) and fails after 3 attempts
the rest of the time. See output below for both cases. I suspect the
issue is the same.
[alderaan] ~/deltas/SPOOL> clogin metro-sw1

I tried the suggested fix, i.e. "one way would be to change the login
prompt regex to "$u_prompt[^a-zA-Z0-9]" and the default u_prompt to
"(Username|Login|login|user name): ?"," but couldn't get it to work -
kept getting a syntax error for the "u_prompt[^a-zA-Z0-9]" bit. I'm not
familiar with expect so was wondering if the syntax given is correct.
The changes I made to clogin and the error message I get are shown
below.
Changed these two lines
if { "$u_prompt" == "" } { set u_prompt "(Username|Login|login|user
name): ?" }
-re "$u_prompt[^a-zA-Z0-9]" {
Get this error message when I run clogin
