The two network has the same configuration from the one we used in class.

Instructions

$$ You need to set up each of the four switches to enable Telnet or SSH$.$

$$ For Switch $1,$ configure all $16$ vty lines to enable telnet using only password to login

$$ For Switch $2,$ configure all $16$ vty lines to enable SSH using only password to login

$$ For Switch $3,$ configure all $16$ vty lines to enable telnet using username and password to login

$$ For Switch $4,$ configure all $16$ vty lines to enable SSH using username and password to login

$$ Use the ip address given below the switch and for all four switch with subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}0.$

$$ Router$1$ and Router$3$s IP is $192\mathrm{.}168\mathrm{.}1\mathrm{.}1$ for fa$0/0($DG for SW $1$ and $3)$and Router$2$ and Router$4$s IP is $192\mathrm{.}168\mathrm{.}2\mathrm{.}1$ for fa$0/0($DG for SW $2$ and $4)$

$$ Note: Router$1$ and $3$ are default gateway for SW $1$ and $3$ AND Router$2$and $4$ are default gateway for SW $2$ and $4$ respectively.

$$ Make sure you test your configuration. From each PC try to telnet or ssh the switch on its network and the other network.

$$ To Telnet from the PC$,$ go to the command prompt and type telnet followed by the switch$$s IP

$$ To SSH from the PC$,$ go to the command prompt and type ssh $-$l followed by the username and IP $($for username and password$)$ OR and type ssh $-$l followed by the hostname and IP $($for password only configuration$)$

$$ If you use a different password from the one given, please indicate it in the comment when you submit.

$$ Use the correct IP address given in the lab. The one given in this document is for demonstration.

Note: Make sure you use the correct default gateway on each switch.

Configuration for telnet with only password

$$ From usermode, enter enable command to go into privilege mode.

$$ From privilege mode, enter configure terminal to enter global configuration mode.

$$ From global configuration mode, enter vty line mode

o Line vty $015$

$$ Enter your password

o password cisco$123$

$$ To enforce it to use only password use login

o login

$$ Type exit to go back to configuration mode

$$ Set enable password $($very important$)$

o enable secret cisco

$$ Enter Interface mode for vlan $1$ to set up the switch$$s IP address $($make sure to use the correct IP address as shown under the switches$)$

o Interface vlan $1$

o Ip address $192\mathrm{.}168\mathrm{.}1\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

o no shutdown $($this command is used to bring up an interface$)$

$$ Type exit to go back to global configuration mode

$$ In global configuration mode, enter the default gateway address $($router$)($make sure each switch has the correct default gateway address$)$

o ip default$-$gateway $192\mathrm{.}168\mathrm{.}1\mathrm{.}1($You need this to be able to go out of your network$)$

$$ In enable mode, verify that your vlan $1$ ip address is set and in up up state using $$show ip interface brief$$ command

Configuration for telnet with username and password

$$ From global configuration mode, enter vty line mode

o line vty $015$

$$ To enable username and password use login local

o login local

$$ Type exit to go back to configuration mode

$$ Set enable password $($very important$)$

o enable secret cisco

$$ Enter Interface mode for vlan $1$ to set up ip address $($make sure to use the correct IP address as shown under the switches$)$

o Interface vlan $1$

o Ip address $192\mathrm{.}168\mathrm{.}1\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

o no shutdown

$$ Type exit to go back to global configuration mode

$$ In global configuration mode, enter the default gateway address $($router$)($make sure each switch as the correct default gateway address$)$

o ip default$-$gateway $192\mathrm{.}168\mathrm{.}1\mathrm{.}1($You need this to be able to go out of your network$)$

$$ Set username and password

o username myUsername secret myPassword

o $($please indicate your usename and password in the file$)$

Configuration for SSH with only password

$$ From global configuration mode, enter vty line mode

o Line vty $015$

$$ Enter your password

o password cisco$123$

$$ To enable it to use only password use login

o login

o transport input SSH$($or use all$)$

$$ Type exit to go back to configuration mode

$$ Set enable password $($very important$)$

o enable secret myPassword

$$ Set up information needed for ssh

o hostname UseSwitchNum

o ip domain$-$name mydomainName.com

o crypto key generate rsa $($press enter$)$

$$ Enter $800$ or $1024$

o ip ssh version $2$

$$ Enter Interface mode for vlan $1$ to set up ip address. $($make sure to use the correct IP address as shown under the switches$)$

o Interface vlan $1$

o Ip address $192\mathrm{.}168\mathrm{.}1\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

o no shutdown

$$ Type exit to go back to global configuration mode

$$ In global configuration mode, enter the default gateway address $($router$)($make sure each switch has the correct default gateway address$)$

o Ip default$-$gateway $192\mathrm{.}168\mathrm{.}1\mathrm{.}1($You need this to be able to go out of your network$)$

Configuration for SSH with username and password

$$ From global configuration mode, enter vty line mode.

o line vty $015$

$$ To enable it to username and password, use login local.

o login local

o Transport input SSH$($or use all$)$

$$ Type exit to go back t
