Purpose Used to configure the DHCP relay feature of the switch.
Syntax
config dhcp_relay { hops <value 1-16> | time <sec 0-65535>}
Description The config dhcp_relay command configures the DHCP relay feature
of the switch.
Parameters hops <value 1-16> – specifies the maximum number of relay hops
that the DHCP/BOOTP packets can cross. The range is 1 to 16. The
default value is 4. The DHCP packet will be dropped when the relay
hop count in the received packet is equal to or greater than this
setting.
time <sec 0-65535> – the secs field in the DHCP packet must be
equal to or greater than this setting to be relayed by the router. The
default value is 0.
