So I've got a situation that I've not seen reference to, so i figured i would post here.
I have two FortiGate 100F devices set up in HA (two ISP's/108F's in SDWAN outside) running 6.4.11.
I currently have a mish-mash of switches inside the network-x1 HP ProCurve 2810-48G, x2 Juniper EX2200 POE, and x1 Dell N2048. All these were in place when I started working here and I have been working to upgrade things as I can. There are multiple VLAN's set up (server, users, voip, printers) and DHCP is handled by an active directory server.
So now I have finally received x5 FortiSwitch 148-FPOE devices and I am working to try to slowly integrate and replace these switches with the existing ones. The new switches will be set up in a ring to the Fortigates via the SFP+ ports.
Is there some documentation or something I have missed that advises in this situation? I am working to replicate the VLAN configs from the established switches, but I am also trying to avoid downtime.
Initially, i planned to try to go switch-by-switch and swap over user connections per switch--however I am running into issues when creating the VLAN's.
For instance, I created the VLAN for our voip phones and set it to pull from the DHCP server. As soon as I enabled the VLAN, all the phones on our network went down. Thing is---i haven't even plugged he switch into anything, other than direct to the Fortigates.
Basically I am looking for anything that guides on how to integrate the Fortigate method of managing VLAN's and such with an already established setup--rather than creating something new.
Thanks in advance for any help.
