Cisco 871W - VLAN-Interface = 'Up/Down'

Hi,

I have configured our company's Cisco 871W per suggested configs found on the cisco web site, however, VLAN1, VLAN10 and VLAN20 interfaces won't come up (e.g. up/down) and it's preventing communication. Guess I'm expecting this to behave like a multi-layer swt/rtr (i.e. 3560). Can anyone help me on this?

Here is the config:

version 12.4

no service pad

service timestamps debug datetime msec

service timestamps log datetime msec

no service password-encryption

!

hostname xxxxxxxxxxxxx

boot-end-marker

End

Sample device-specific configs would help.

We are not concerned with the wireless portion of the config at this point.

Any insight is appreciated.

Thanks!
