ACLs and MAC addresses
Is it possible to apply ACLs or filter network traffic on a MAC address basis, ie: is it possible to lock out unknown machines?
thanks!

Re: ACLs and MAC addresses
thanks for your reply.
We've got a Procurve 5308XL with software version E.07.27, simple-default configuration and no VLAN.
We have a lot of visiting students' notebooks connecting to the Procurve switch and a win2003 DHCP server leasing IP addresses also connected to the switch.
I'd need to filter IP requests/offers on a MAC address basis, in order to allow access to the LAN only to known students' machines directly connected to the Procurve switch avoiding unknown machines or known machines not directly connected to the switch to get acces to the LAN.
Can you give a schematic idea of things to do and point me in the right direction?
Thanks a lot!
Andrea

Re: ACLs and MAC addresses
The essential difference between the two is that bootp has to have a list of MAC addresses matched to the ip addresses you want assigned to them. You create this list in the same DHCP management module - look for reservations.

Re: ACLs and MAC addresses
There is a lot of other good info in there as well.
It can be downloaded from ftp://ftp.hp.com/pub/networking/software/59906052.pdf

Re: ACLs and MAC addresses
Attempts to enforce MAC address restrictions at the switch will limit the use of a switch port to a particular MAC address potentially causing two issues - a given student cannot take his/her notebook from one classroom to the next as well as unused switch ports not being available for use by students that they have not been assigned to.
I have no idea if either of these is a concern in this environment, but it is at my daughter's campus, where access is controlled as I describe.
