This week is going to be very interesting as I'm trying to implement my subnet, vlan and authentication changes all in one go.
I thought I might add a few posts now and then of progress if anyone else is interested in 802.1x and procurves.
Monday, day 1
I changed all the ip addresses of the servers (all 20+) in line with their new ranges to match the vlans. I have split the servers across 2 VLANs one for general access servers and one for admin.
I have the new HP5412zl sat on my desk.
Most vlans have been created, ip routing has been enabled on the switch and those vlans that need it have been assigned an ip address and DHCP helper.
ACLs: I am now experimenting with ACLs to block traffic from being routed to the admin VLAN from those that don't need access. This is a feature of the 54xx switches.
ACLs working! I can apply ACLs to the vlans to stop traffic being routed to specified VLANs.
Today will be a reconfiguration of my ESX servers to bring them inline with the new vlans and their IDs on the new switch before I can start with 802.1x.
