server
Property Description
name (name) - descriptive name for relay
interface (name) - interface name the DHCP relay will be working on
dhcp-server (text) - list of DHCP servers' IP addresses which should be the DHCP requests
forwarded to
local-address (IP address; default: 0.0.0.0) - the unique IP address of this DHCP relay needed for
DHCP server to distinguish relays:
• 0.0.0.0 - the IP address will be chosen automatically
Notes
DHCP relay does not choose the particular DHCP server in the dhcp-server list, it just sent to all the
listed servers.
Example
To add a DHCP relay named relay on ether1 interface resending all received requests to the
10.0.0.1 DHCP server:
[admin@Wandy] ip dhcp-relay> add name=relay interface=ether1 \
\... dhcp-server=10.0.0.1 disabled=no
[admin@Wandy] ip dhcp-relay> print
Flags: X - disabled, I - invalid
# NAME INTERFACE DHCP-SERVER LOCAL-ADDRESS
0 relay ether1 10.0.0.1 0.0.0.0
[admin@Wandy] ip dhcp-relay>
