DHCP
♦ Use DHCP: Sets the way your system utilizes the Dynamic Host Configuration
Protocol (DHCP, used for automatic IP assignment).
Always: The system searches for a DHCP server each time the unit is
turned on.
Smart: The system searches for a DHCP server only if no IP address was
assigned. If an IP address was assigned manually, the system will not
search for a DHCP server.
Never: The system never searches for a DHCP server.
The default value is Smart.
NOTE:
When the unit is configured to use a DHCP server and none exists, the unit will assign itself an
automatic class B address in the range 169.254.X.X; this can be used with Auto Discovery when the
MAC address is not available.
VLAN Support
♦ VLAN ID Management: The VLAN ID Management defines the VLAN ID for
management frames, which identifies remote stations for management
purposes. This applies to all management applications using protocols such as
SNMP, TFTP, ICMP (ping), DHCP and Telnet. When management VLAN is
enabled, all servers/stations using these protocols must tag the management
frames sent to the unit with the value of the VLAN ID Management parameter.
Operation with Management VLAN enabled (VLAN ID Management is 1-4094):
• Management VLAN
•VLAN ID from 1 - 4094
•Set separately for the BU and for each RB
Important note:
Management VLAN for RBs over the AIR assumes Data VLAN is disabled
