Quick Steps for Setting Up DHCP Relay
You must configure DHCP Relay on switches where packets are routed between IP networks.
There is no separate command for enabling or disabling the relay service. DHCP Relay is automatically
enabled on the switch whenever a DHCP server IP address is defined. To set up DHCP Relay, proceed as
follows:
1 Identify the IP address of the DHCP server. Where the DHCP server has IP address 128.100.16.1, use
the following command:
-> ip helper address 128.100.16.1
2 Set the forward delay timer for the DHCP relay. To set the timer for a 15 second delay, use the
following command:
-> ip helper forward-delay 15
3 Set the maximum hop count value. To set a hop count of 3, use the following command:
-> ip helper maximum-hops 3
Note. Optional. To verify the DHCP Relay configuration, enter the show ip helper command. The display
shown for the DHCP Relay configured in the above Quick Steps is shown here:
-> show ip helper
Ip helper :
Forward Delay (seconds) = 15,
Max number of hops = 3,
Relay Agent Information = Disabled,
PXE support = Disabled,
Forward option = standard mode,
Bootup Option = Disable
Forwarding address list (Standard mode): 128.100.16.1
