How to set password setting in a router and telnet

                                                          

 

3.   enable secret

        This password is also use for privilege mode but it has priority over enable password and                                         it is always encrypted

 

  To set password:

     R(config)# enable secret  cisco

     R(config)#^Z

  To remove password:

    R(config)# no  enable secret

    R(config)#^Z

  NOTE:  To check passwords

     R# show running-config

NOTE: Password is never encrypted in Telnet

NOTE :

By default telnet session is not possible without any password but to connect telnet without using any password :-

R(config)# line  vty    0   1      <┘    (for   2  sessions)

         # no login    <┘

         # ^Z        

NOTE: We can use the following command to copy  NVRAM into DRAM :-

R# copy     startup-config    running-config   <┘
