Only protected ports cannot talk to each other. Anything else works like
normal!

Hi ..
So the anyone connected to to protected port can not talk to any protected
port ?
What about the ports that are connected on the same VLAN without the
configuration of the protected part, can they pass traffic to this protected
ports?
Can you please show us an Example about this in real life
Thanks for the Reply Scott

It's "edge" as in, it can't be a trunk port. Consider your entire switch is
in two VLANs, half in VLAN 10 half in VLAN 20. Obviously the two VLANs
won't talk to each other unless you configure routing and SVIs. Beyond
that, INSIDE a VLAN, if we configure certain ports as "switchport protected"
then they will never ever talk to each other on an L2 basis. no unicast,
multicast or broadcast.
So the logic really isn't the same as a CE/VRF in the MPLS network. It's
only deployed at the access switch itself. If you had two different
switches involved, it really wouldn't have the same effect. Whereas in
"real" private VLANs the restrictions would follow.
HTH,
Scott

Quick Question
So only on Edge Ports?
Interface Role Sts Cost Prio.Nbr Type
---------------- ---- --- --------- --------
--------------------------------
Fa0/2 Desg FWD 19 128.2 Edge P2p
What if are talking dot1q or ISL with another switch ?
or maybe a solution using VRF
What means the term Vlan Edge Ports == It's like a CEdge in MPLS? and this
ports looks like an Interface in a VRF?
Thanks

They're listed in the release notes as an impending feature. You can do the
private vlan edge ports "switchport protected" though...

I've been reading this conversation and I wanted to share the fact
that private VLANs are NOT supported in the 3550. The 3560 and 3750 has
private VLAN support, but the 3550 does NOT (according to the feature
navigator www.cisco.com/go/fn and the latest documentation).
Cheers,
Dennis Hartmann

Sorry, my question should have been clearer. I think Scott may have read
between the lines anyway, and answered my question.
My current understanding is that a subset of private vlans is available and
testable (potected ports) but the full implementation of private vlans
(host, isolated, community etc) is not. The documentation seems to confirm
it, although the 3550s have the commands available.
So, as it stands, I should know protected ports. I'm also going to spend a
few minutes looking at how its implemented in the 3750 so I don't get any
nasty
shocks(http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3750/12220
se/3750scg/swpvlan.htm),
and then I'll move on.
I think this looks like a great feature, BTW. I can think of plenty of
places I could use it.
Thanks all,
Roy

Lee,
I don't think private vlan's is available on 3550's although there are
plenty of other port security features.
If you have a link for private vlans on a 3550 could you post it
please?
TIA, Tim

Hi,
I'm not as clear about IOS versions on switches as I am on routers.
Anyone know if the private vlans feature is available on the 3550's
yet? If not is it likely to be? And if it does become available, does
it become fair game on the lab straight away, or should we get an
announcement?
--Regards,
Roy
