DHCP/BOOTP request. If this time is larger than the DHCP packet's time, the switch will drop
the DHCP/BOOTP packet. The range is 0 to 65535. The default value is 0.

22-2 config dhcp_relay add ipif
Description
This command is used to add an IP destination address to the switch's DHCP relay table.
Note: Adding a server to which DHCP packets will be relayed, will cause the switch to intercept
DHCP packets on the specified VLAN, and relay them directly to the specified server. DHCP
packets will not be broadcast on the VLAN. To restore broadcast functionality, see the
"dhcp_local_relay" command
Format
config dhcp_relay add ipif <ipif_name 12> <ipaddr>
Parameters
<ipif_name 12> - Enter the name of the IP interface which contains the IP address below.
<ipaddr> - Enter the DHCP/BOOTP server IP address.
