Layer 2 Port Isolation

Hi all !

I would like to know if I can get Layer 2 port isolation on procurve switches.
I would like to have

ports 1-10 to talk to port 11 with full layer 2
but not seeing each others.

Is this possibile ?

Is available an example for

26xx series
28xx series

What procurve switch can do this ?

Re: Layer 2 Port Isolation

Hi Tom,
take a look at the "filter by source-port"

This functionality on the 2600's allows you to drop inbound traffic at a source port if it is destined for another port that matches the filter definition.

E.g. in your case port 1 would drop 2-10 and anything beyond 11. Port 2 drops 1,3-10,12-24 etc.
# filter source-port 1 drop 2-10,12-24
# filter source-port 2 drop 1,3-10,12-24

I would test it out and see if it works for you. It's kind of port based zoning for LAN switches.

Hope that helps - please click "Thumbs up" for Kudos if it does
