creating layer 3 SVI

HI guys, I have an issue with my cisco 851W router

when I try to configure fast ethernet port , I keep getting an error:

IP addresses may not be configured on L2 links

according information from the forum I have to :

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

conf t

int <interface name/no>

no switchport mode

ip address x.x.x.x x.x.x.x

it`s still getting the error

or if you want the port to be a member of VLAN, do this-->

conf t

int vlan <no>   

ip address x.x.x.x x.x.x.x

int <interface name/no>

switchport access vlan <vlan name/no>

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

for instance if the internet comes via cable from 192.168.66.101 255.255.255.0

I have to configure

conf t

int vlan 1  

ip address 192.168.66.101 255.255.255.0

int fastethernet 0

switchport access vlan 1

is this correct?

thanks in advance for your help

best regards

Hi,

Just create create the SVI and connect the connection on any port as by default all the ports are in vlan 1.

Thanks

thank you very much indeed for your fast reply

the configuration should be:

R1#conf t

R1(config)#int vlan 1  

R1(config-if)#ip address 192.168.66.101 255.255.255.0

R1(config)#interface fastEthernet 0
R1(config-if)#switchport mode access
R1(config-if)#switchport access vlan 1
R1(config-if)#no shut

thanks in advance

best regards

Hi.
