vlan support on a 4700m

I doubt it. The 4700's were End-of-lifed over 10 years ago, which is why you picked it up cheap.

There was a thread about this recently regarding a different router model - maybe 2600.

In my experience having IOS versions that allow non functional configurations in a new thing. I think it may work - however you probably need another 4500m to connect it to. Or at least a second int on the same box.

If you have docs for th NM check there.

Works perfectly fine with the 10 Mbps interfaces, if the bandwidth is enough for your needs. Have been using it for years myself.

Nah. It does perfectly normal IEEE 802.1q encaps like any decent Ethernet switch out there. I ran it against a 3Com SSII 3300 without any probs.

I have a Aironet 350 AP here, the plan was to set up a second vlan so my neighbors kid can hook up and surf, I just wanted to put them on a separate subnet and acl them off from my stuff. I will give it a go, thanks for the info

This is a 4700M Router, not a switch. The 4700 was Cisco's first modular router that had three slots and you had to pull the thing apart to get the modules in. Your probably referring to a 4000 or 4500 series switch which does do 802.1q.

I have the idea that 802.1q was never included officially in 10M bps 802.3 ethernet and was not widely supported by Cisco. I also have the idea that Cisco did support trunking (ISL or maybe 802.1q) on some 10M /router/ ports at least.

Not sure though and I'm not looking it up at the moment either since I can't imagine that I will never need to know.

which, with this configuration snippet:

talks 802.1Q perfectly fine to a 3Com SuperStack II 3300.

Any questions?

What's the MTU on the sub-interfaces?
