Restriction on telnet Access

[Amin Shaikh]

Hi,

How to restrict a subnet only to telnet to a router or a switch.

I need to create local user and password.

Hi Amin,

You need to configure ACL and apply the ACL into the VTY

If you want to create local database for user and password, you can do

username xyz password xyz

HTH,

Hi,

An example:

You wish to restrict the users of the 10.10.10.0/24 subnet to be able to have telnet access to a router or switch:

access-list 1 permit 10.10.10.0 0.0.0.255

username xxx privilege y password zzz

line vty 0 4

access-class 1 in

transport input telnet

login local

Cheers:
