Hi,

You can try to clear stull TCP sessions within your switch.

You can first try to clear it with "clear tcp line #".

If did not help then check for those with show tcp brief

Those which are not established - are subject to be cleared.

You can clear those with

clear tcp tcb TCB_NUM (TCB_NUM from command show tcp brief).

Hope this helps,

Nik

HTH,

hi maxim,

nice command you got there. i didn't even know the "who" command exist. i often used the show users command.

try using clear line 0 (without the "vty") instead.

hi john!

command without "vty" dont take effect as with "vty", session still exist.

hi maxim,

can you schedule a downtime and perform a reload on your switch?

hi jonh!

unfortunately i cant do it for now, this problem not so critical and this switch aggregate too many L2 sw. I shedule it for future.

thanks for help
