3.9 DHCP Boot
The DHCP Boot page (Figure 3-25) allows the user to configure the boot up and DHCP request delay for
the switch. Enabling DHCP Broadcast Suppression will cause the switch to delay booting up for between
1 and 30 seconds to avoid overloading the DHCP server with requests in the event of a building-wide
power failure. If all of the devices are powered up simultaneously and all request IP addresses using
DHCP at the same time, it may cause an overload on the network or on the DHCP server. Delaying the
DHCP request using this feature will prevent this from happening.

3.10 VLAN
The switch supports both Tag-based VLAN (802.1Q) and Port-based VLAN. It supports 256 active VLANs
and VLAN IDs from 1 to 4094. VLANs are used to partition your LAN into smaller ones to prevent different
networks from talking to each other, and to limit broadcast domains. Properly configured, VLANs provide
improved security and performance on the network.
3.10.1 VLAN Mode
The VLAN Mode page (Figure 3-26) allows the user to select the VLAN mode to use. Five modes are
available: Port-based, Tag-based, Metro Mode, Double-tag and Disable. Select the desired mode and
then click Apply. The settings will take effect immediately.
VLAN Modes:
Disable: Disable VLANS on the switch. This is the default setting.
Port-based: Port-based VLANs are defined by port. No filtering is applied to the packets on each port,
the only limiting factor is that only ports in the same VLAN can communicate with each other. Each port-
based VLAN must be assigned a unique group name. The switch can support up to a maximum of 8 port-
based VLAN groups.
