Our network is made up of devices from various vendors - Brocade/Foundry, Cisco and HP switches - inc layer 2/3 devices. SAN From Dell, Tape Backup from Dell.
I have inherited the network with no documentation what so ever. I need info on ports, vlans etc so that I can not only understand how it was setup for also help with with upgrade/replacing all devices to one vendor - preferably HP Procurve.
I am looking for free tool to do this.
