Hi.

I'm curious about line bysy therefore cpu of the router up high.

I tried to show status of the line by using "show line" command. the result is below.

TS#sh line

I did't try to connect vty 2,3,4,5,7,11,12.

But the line is busy...

Acually, this router(C2500) is terminal server.

How can i fix it?

Lines 2,3--11,12 are tty lines not vty. The vty lines are 18-22.

You probably have some active session on those tty lines so are getting a busy. "show session" will indicate the same.

In order to clear the lines (say line 3);

Router#clear line 3

[confirm]

[OK]

Thanks, Mak
