Hi Simon, That is correct we are using dhcp-relay on our switches
My concern with removing them completely is that the devices will no longer respond to ping, we use a Web based systems to send dat to them (they are label printers) that depends on the device to be ping-able to send the print jobs to them. As for tagging - Are you saying i would be able to tag the correct gateway to correspond with my Option 82 statements? below is part of my dnsmasq.conf file dhcp-circuitid=set:01_port_01,temp-2b.plant.ldn01:ge-0/0/12.0:pack1-5-302 dhcp-circuitid=set:02_port_02,temp-2b.plant.ldn01:ge-0/0/6.0:pack1-5-302 dhcp-circuitid=set:03_port_03,temp-2b.plant.ldn01:ge-0/0/2.0:pack1-5-302 dhcp-circuitid=set:04_port_04,temp-2b.plant.ldn01:ge-0/0/18.0:pack1-5-302 dhcp-circuitid=set:05_port_05,temp-2b.plant.ldn01:ge-0/0/9.0:pack1-5-302 dhcp-range=net:01_port_01,temp-2b.plant.ldn01:ge-0/0/12.0:pack1-5-302,10.192.4.11,10.192.4.11,255.255.255.0 dhcp-range=net:02_port_02,temp-2b.plant.ldn01:ge-0/0/6.0:pack1-5-302,10.192.4.21,10.192.4.21,255.255.255.0 dhcp-range=net:03_port_03,temp-2b.plant.ldn01:ge-0/0/2.0:pack1-5-302,10.192.4.31,10.192.4.31,255.255.255.0 dhcp-range=net:04_port_04,temp-2b.plant.ldn01:ge-0/0/18.0:pack1-5-302,10.192.4.41,10.192.4.41,255.255.255.0 dhcp-range=net:05_port_05,temp-2b.plant.ldn01:ge-0/0/9.0:pack1-5-302,10.192.4.51,10.192.4.51,255.255.255.0 Thanks!
