Syntax config dhcp_relay {hops <value 1-16> | time <sec 0-65535>}(1)
Description
This command is used to configure the DHCP/BOOTP relay feature.
Parameters
hops <value 1-16> − Specifies the maximum number of relay agent hops that the DHCP
packets can cross. The Default setting is 4.
time <sec 0-65535> − If this time is equal to or more than the entered value, the Switch will
relay the DHCP packet. The Default setting is 0.

Syntax config dhcp_relay add ipif <ipif_name 12> <ipaddr>
Description
This command adds an IP address as a destination to forward (relay) DHCP/BOOTP relay
packets to.
Parameters
<ipif_name 12> − The name of the IP interface in which DHCP relay is to be enabled.
<ipaddr> − The DHCP server IP address.
