We have multiple VLANs in our environment. The DHCP servers are on VLAN 320, while a couple of workstations are on VLAN 646.
To allow the workstations to find a DHCP server, we use the below command on our Procurve
ip address 10.0.32.1 255.255.255.192
ip address 10.0.64.49 255.255.255.240
ip helper-address 10.0.32.4
ip helper-address 10.0.32.3
With Procurve switches, you can specify an "ip helper-address" command. What is the command to do the same thing on a Cisco SG-300 (28-port) switch. This is a Small Business Switch, which I believe was bought out from Linksys. So the commands differ slightly.
