4.10 DHCP Boot
To get to this screen, click on DHCP Boot in the Home menu. The DHCP Boot function spreads the request
broadcast packet into a bigger time frame to prevent traffic congestion.
The switch supports a random delay time for DHCP and boot delay for each device. This suppresses the
broadcast storm while all devices are at booting stage at the same time. The maximum user-defined delay time
is 30 seconds. If the DHCP Broadcasting Suppression function is enabled, the delay time is set randomly,
ranging from 0 to 30 seconds, because the exact delay time is computed by the switch itself. The default is Disable.

4.11 VLAN
To get to this screen, click on VLAN in the Home menu. The switch supports Tag-based VLAN (802.1q) and
Port-based VLAN (256 active VLANs with VLAN IDs 1–4094). VLAN configuration is used to partition your
LAN into small ones as needed. This improves security and increases performance while greatly reducing
VLAN management.
