Hi guys,
I’m trying to create several vlans on a 1720 router. IOS is IP PLUS IPSEC 3DES.
I’m running into problems when I try to add the “encapsulation dot1q” command in the subinterface.

duststorm(config)#int f0.10

duststorm(config-subif)#encapsulation dot1q 10

duststorm(config-subif)#

I was under the impression that IP PLUS feature set allows vlans. Not to mention Cisco’s vlan walkthrough for 1700 series says it should work:

Any ideas?
