None. Neither supports 802.1Q.

Marco.

802.1Q Trunking: CAT4000 with SUP*, subsets of 12.1(*)E*, such as
SUP2-PLUS and 12.1(19)EW.

802.1Q VLAN support: similar to above, but not SUP2-PLUS, but adds AGM.
Prety much the same IOS versions.

Yep, de *Catalyst* 4000 supports it. But I assumed he was talking about
de Cisco 4000 router, not the switch. And the router doesn't.

Regards,

Marco.

Dang model number overloading! That's worse than the C2948G
being different than the C2948G-L3!

really? the 4000-series router doesn't support it... even with the use of a
fast ethernet interface?

quick question, do the 5000-series switches work with 802.1q?

Marco is correct: the Feature Navigator does not list 802.1Q as
possible for the 4000-series router or the 2500 series.
The 4500 series was supported from 12.0T.

:quick question, do the 5000-series switches work with 802.1q?

Yes, from 12.0T for the RSM, and 12.1 for the RSFC. (The Feature Navigator
does not index CatOS features, so I cannot easily give you information
about the bare switch itself.)

Correct. Early fast ethernet card designs could not support it.

Scenario:
we have 13 floors in our building. All the floors come down into the same
switch via gig links. Each floor is an individual subnet vlan. That switch
then communicates to other server farm switches via a gig uplink. The
problem we want to remedy is how to keep workstations that are infected with
Blaster or future variants from "blasting" each from floor-to-floor. By this
I mean, if we have infected machines on the 5th floor then they will bombard
clients on the other floors. What is the best way to contain this situation?
Should I use the IDSM-2 to shun these attacks via dynamic VACLs or should I
use NBAR for this situation or even just private vlans?? Of course private
vlans will only help on each respective vlan subnet. Also, If I use NBAR
(IDSM-2 too??) will it block all good traffic as well? I know with NBAR I
Can have it drop traffic altogether which is the ultimate goal. I have read
the following SAFE document and it is very good but it still leaves many
questions unanswered. There is an NBAR sample config there as well.
