Hey everyone, I am trying to configure the interface vlan1 on my router but it's not giving me that option. I have been able to do this before on similar routers. Any ideas?
router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface vlan 1
^
% Invalid input detected at '^' marker.

router(config)#interface ?

There is an important difference between your 1941 routers. The first one is a regular 1941 which you can see in the output of show version
Cisco CISCO1941/K9 (revision 1.0) with 491520K/32768K bytes of memory.
And the second one is a 1941W which you can see in the output of show version
Cisco CISCO1941W-A/K9 (revision 1.0) with 483328K/40960K bytes of memory.
And one of the results of this difference is that the second 1941 has some components that the first one does not have
3 Gigabit Ethernet interfaces
4 terminal lines
1 Virtual Private Network (VPN) Module
2 Cellular interfaces
1 cisco Embedded AP (s)
The embedded AP in the 1941W is what gives you the ability to configure interface vlan 1 on this router. Since the first 1941 does not have this other component then you are not able to configure interface vlan 1 on the first 1941.

Interface vlan 1 works on switches. If this router had a switch module as part of it then you would be able to configure interface vlan 1. But this router has no switch module, at least according to the information about components in show version
2 Gigabit Ethernet interfaces
1 terminal line
1 Virtual Private Network (VPN) Module
So you can configure the Gig Ethernet interfaces but not interface vlan 1.

Hi Richard, thanks for the reply. Interestingly enough though, I have another 1941 router that has VLAN interface configured. There are actually quite a few of them.
