Re: DHCP on ProCurve 5412zl
Also, are you having it do any routing?

Re: DHCP on ProCurve 5412zl
show ip helper-address vlan 100
IP Helper Addresses
IP Helper Address
-----------------
10.0.0.184
show ip helper-address vlan 200
IP Helper Addresses
IP Helper Address
-----------------
10.0.0.184
10.2.200.1
What I want to do is add an ip helper-address for 10.2.200.1 to the vlan 100 which has been setup already in the vlan 200, as I need our DHCP backup server to, run on both vlans like the 10.0.0.184 DHCP server is . . .

Re: DHCP on ProCurve 5412zl
vlan 100
ip helper-address
exit
show ip helper-address vlan 100
Due to the nature of the command I'm guessing if the backup DHCP server is on vlan 100 it doesn't need this command - it'll just be redundant.
http://www.procurve.com/network-pro-news/articles/network-rxmar08.htm
The minimum requirements for DHCP Relay Operation are:
1.DHCP Relay is enabled on the routing switch (the default setting);
2.A DHCP server is servicing the routing switch;
3.IP Routing is enabled on the routing switch;
4.There is a route from the DHCP server to the routing switch and back;
5.An IP Helper address is configured on the routing switch, set to the IP address of the DHCP server on the VLAN connected to the DHCP Client.
DHCP relay is enabled by default. If it has been disabled, it can be re-enabled simply by issuing the command:
ProCurve Switch(config)# dhcp-relay
Next, configure the IP Helper Address on VLANs where clients will reside:
ProCurve Switch(config)# vlan 2
ProCurve Switch(vlan-2)# ip helper-address
