hi

I need help about Cisco switch 2960 issue how i give IP address gateway in switch if there more than two vlan  and how configure  telnet command

You can have one management vlan available. Let's say it's vlan 1 which is default. To configure:

int vlan 1

ip address 192.168.1.1 255.255.255.0

no shut

A basic telnet session is:

line vty 0 4

password cisco

You can get more granular with usernames like using local accounts and radius authentication for telnet as well. You'll also need an enable password before you can telnet:

enable secret cisco

HTH,

John

thanks a lot john

if we create extra vlan and not access any interface and just give ip address and not shut command then it work

Hi,

Do you have Lan Lite or Lan Base license (check with "show version")? LAN LITE does not permit routing.

With LAN BASE:

sdm prefer lanbase-routing // save before your config, you may loose some configuration

reload the switch

Example for gateway configuration:

vlan 10

vlan 20

interface vlan 10

ip address 10.0.10.1 255.255.255.0

interface vlan 20

ip address 10.0.20.1 255.255.255.0

For telnet:

username name privilege 15 secret password

line vty 0 15

login local

transport input all

But, do not use telnet (all traffic passes on clear including passwords), use instead ssh if the switch permits:

hostname switch

ip domain name company.com

crypto key generate rsa general-keys modulus 2028

line vty 0 15

login local

transport input ssh

Hope this could help you!
