I need to combine 3 switches in to 1 terminal so i dont have to keep switching my console cable to each switch,

so its something called telnet., there is also something about making a "management vlan" so im supposed this is the vlan ip address i telnet onto.

Not sure how to do this, if someone can explain and show me step by step id extremely appreciate that, thanks.

    Buddy, you seriously need to read some info first. If you need some help, you can begin providing some info about your equipment. – Orlando Gaetano Jul 19 '16 at 23:50
  • I tried and I am a little lost between management vlan and telnet and how they relate. I have 2 3560s and 1 2960 switch. And so I want 3 telnet sessions, il be connecting a firewall later – Stan234 Jul 20 '16 at 1:47
  • Do you have any kind of managment network??, cause you need 3 IPs, one for every switch – Orlando Gaetano Jul 20 '16 at 2:36
  • Orlando, you seriously need to read some info first. He does not want to keep switching his Console cable. Console access does not rely on IP addresses. He does not need any IP addresses at all. He needs a Terminal Server. – Ron Royston Jul 20 '16 at 5:06
  • His question is vague enough that configuring the 3 switches with IP addresses and telnet access would basically satisfy his requirements. – Mark Jul 20 '16 at 12:49

You can use the steps described upside. Only some explanation

router#configure terminal

router(config)#username user1 password pass1
router(config)#username user2 password pass2
router(config)#line vty 0 4

! Whe you put login local i to line vty 0 4 ! You are refering to all the local users ! Those that you are declared like !username

router(config-line)#login local

Console access into several networking devices is provided via a Terminal Server.

Configure Terminal Server through Menu Options

Cisco Router configured as Terminal Server with an Async module like HWIC-8A, called octopus cable.

enter image description here

switch> en
switch# conf t
switch(config)# username cisco priv 15 password cisco
switch(config)# int vlan 1
switch(config-if)# ip addr
switch(config-if)# no shut
switch(config-if)# line vty 0 4
switch(config-line)# login local
switch(config-line)# end
switch()# wr mem

This configures a user to login with, creates a vlan interface to connect to, and then allows telnet to one of the virtual lines (vty). Ignore the management vlan for now, vlan 1 works fine. Plug your ethernet cable into the switch and telnet to

If you have any questions, everyone here is happy to help, but you should be able to find this stuff in numerous docs online.

  • i am doing that and trying to access vlan from another switch, but it says Switch#telnet Trying ... Open Password required, but none set [Connection to closed by foreign host] do i have to do those commands on the other switches for it to work – Stan234 Jul 20 '16 at 13:21
  • @Stan234 You can try going into line vty 0 4 and entering "login" and "password cisco". You shouldn't need to do this though if you correctly have "login local" on the lines and a user created. – esafresa Jul 21 '16 at 15:16
