Re: Switch config

Hi Antony,

You can cofigure a seperate SVI and configure that SVI with the ip address in same subnet which you will be configuring on the lan interface of your router.

Once done you can configure any layer 2 port on your 4k switch with that vlan for which you have configure SVI.

Some thing like this on your on 4k switch


interface Vlan 7

description Router

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


interface fa4/20 <====any interface type/num

switchport mode access

switchport access vlan 7

Connect your fa4/20 to your lan interface of your router and assign an ip address in same subnet which is configured on SVI of vlan 7.

HTH, if yes please rate the post.
