Q: 802.1q support on 4000 series routers - can it run over the Ethernet interfaces or must it go via Fa ?

HSB, Thanks for the quick reply. I know that the 2610s do it as of 12.2(2)T and was wondering about the 4000 series as well.

That's because FastEthernet does not seem to be supported on the 4000s (only on the 4500s and 4700s) yet they seem to have 802.1Q support as per::

I'm after a few 4500s and if I can do without the NP-1FE modules ($100-$150 each) then I'll be very happy.

Thnx, V

I wouldn't bet on it. It doesn't say that 10Mbps NPs can do dot1Q.

Thanks Brad. Unfortunately the CPQRGs are not usually detailed enough and one has to search thru the feature list of a particular IOS release.

Having said that, thanks for including those guides on your site as they can be quite useful as a starting point for ppl who search for general details on end-of-line products. I know how much time can be wasted on Google searching for stuff just like that. I'm surprised they are not on Cisco.com (unless I could not find them)...

Cheers, Wojtek

I would not want to bet on it either HSB (and thankfully I don't need to). However this is exactly why I posted my Q as the doc I listed seemed to suggest that this is possible. Hence, I was wondering if there was anyone around who has had similar experiences and success with dot1q on the 10MB interfaces on a 4000 series.

I guess one way to find out is to buy a 4500M with the Ethernet module and check. If it does not work then I'll need to get the additional NP-1FE modules.

Let me think about that one tho...it's a 2 horse race at the moment: a 4500M vs a 2611...ohhh, and it's only for a home lab just in case anyone asks. Hence, I'm trying to spend the $$$ wisely.

Thnx, Voitec

Perhaps it depends on the IOS? I know a 2620/10 with a NM-1E will run dot1q on the 10 mbps Ethernet port with certain IOS's but won't with others. Knowing that the 4500/4700's are dead to Cisco, perhaps the IOS's don't support trunking on a 10 mbps interface.

What's the IOS release? What's the min/max memory requirement? I have a 4500M that I can test with...
