Switch Config Issue

Hi Team,

We are facing issue with one of our terminal server after recover password.

After login our TS it's showing like below, we can able to lgin and see the confif as well.

And one more issue with our Nexus switch console, all of out Nexus 5K as well getting continuos error like below

After Login TS:

--------------

login as: xxxx

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device.

This feature requires the one-time use of the username "cisco" with the

password "cisco". These default credentials have a privilege level of 15.

YOU MUST USE CISCO CP or the CISCO IOS CLI TO CHANGE THESE  PUBLICLY-KNOWN

CREDENTIALS

Here are the Cisco IOS commands.

username <myuser>  privilege 15 secret 0 <mypassword>

no username cisco

Replace <myuser> and <mypassword> with the username and password you want

to use.

IF YOU DO NOT CHANGE THE PUBLICLY-KNOWN CREDENTIALS, YOU WILL NOT BE ABLE

TO LOG INTO THE DEVICE AGAIN AFTER YOU HAVE LOGGED OFF.

For more information about Cisco CP please follow the instructions in the

QUICK START GUIDE for your router or go to http://www.cisco.com/go/ciscocp

-----------------------------------------------------------------------

Using keyboard-interactive authentication.

Password:

% Password expiration warning.

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device

and it provides the default username "cisco" for  one-time use. If you have

already used the username "cisco" to login to the router and your IOS image

supports the "one-time" user option, then this username has already expired.

You will not be able to login to the router with this username after you exit

this session.

It is strongly suggested that you create a new username with a privilege level

of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to

use.
