ICX-7750 DHCP Server on a specific VLAN

brian_baggett — Wed, 20 Oct 2021 15:39:08 GMT

I have a ICX-7750 that has 4 vlans, is there a way to turn on DHCP server for just one specific vlan and it assign IP addresses to just that vlan without interfering with the other vlans? I need this vlan to have its own different IP addresses from the other vlans.

DHCP is vlan specific as it’s a broadcast, so when you define the option 3 (GW) that’s the only vlan that will hear and receive addresses.

ie, port 1 in vlan 10 and you configure vlan 10 dhcp pool, devices in any other vlan won’t receive any.
