default vty in 3560

josephschung — Thu, 07 Mar 2019 01:11:56 GMT

A brand new 3560 does not has password and comes with the following vty settings. The console access has no problem. But for telnet...

line vty 0 4
login
length 0
line vty 5 15
login
!

Does it allow telnet to get in? Should it allow telent automatically?

Is there any document to explain the commands?

Thanks

Hi,

You need to set a password to access C3560 via line vty. There are many methods to access the device. You can use username/password to authenticate as well.

For example

C3560(conf)#line vty 0 15

C3560(conf-line)#password Cisco

C3560(conf-line)#login

In this case,you need to define "enable [password or secret]" to get configuration mode on the device.

C3560(conf)#enable password Cisco

Thanks for the information.

Usually I will create local account and use "login local" to let telnet work. But for the new switch default configuration, my questions are:

1) Does the default setting allow telnet (without any password)?

2) Where can I have comprehensive explanation of the vty commands such and "login" and "length"?

Thanks.
