Hello Egis,

you need to get enabled access

to do this after accessing the router prompt

something like

router>

you need to do

router>enable

you are prompted to enter enable password

once you are in enabled mode prompt changes to

router#

to check the ip addresses in your router do

sh ip interface brief

example

sh ip int brief

Interface IP-Address OK? Method Status Protocol

FastEthernet0 unassigned YES unset up up

FastEthernet1 unassigned YES unset up down

FastEthernet2 unassigned YES unset up down

FastEthernet3 unassigned YES unset up down

up up

Vlan1 10.34.16.177 YES NVRAM up up

Tunnel92 10.80.240.92 YES TFTP up up

Loopback8 10.80.240.92 YES NVRAM up up

up up

Loopback2 unassigned YES NVRAM up up

Vlan3 unassigned YES NVRAM up down

if you need to change address on an interface you need

to do

config t

interface vlan1

ip address 10.50.50.1 255.255.255.0

end

wr mem

this should be enough

Hope to help

Giuseppe's post is right.

Just another hint: If you want to change the IP Address make sure you are not telneting into the same IP Address otherwise you'll loose connection.

If your router has a loopback ip address, I recommend you telnet into that IP Address.
