Hey all. I usually use 1750 routers and connect E0 to the WAN link and FA0 to the LAN ip.

Now, I have an 181 with 2 FA ports and an 8 port built in switch. How can I put all 8 ports into a vlan sharing the same ip range so that I don't have to use an external switch directly plugged into fa1?

Assume that fa1 is ip

router(config)# vlan database

router(vlan)# vlan 10 media ethernet name vlan10

router(vlan)# exit

This will create your vlan.

Create your layer 3 interface for vlan 10

int vlan 10

ip address

no shut

to add ports to that vlan

int fa2

switchport mode access

switchport access vlan 10

spanning-tree portfast

All the switch ports are in VLAN1 by default, but this is a more secure method.

And FYI, in global config mode, you can do "int range fa2 - 9" and edit all 8 switch ports at once.

Saves a little time. And only use the portfast command if you're sure no one will be plugging in any switches downstream.
