BOOTP/DHCP Relay

To enter the IP addresses of BOOTP or DHCP servers (for the BOOTP/DHCP Relay service):

Highlight Utilities on the Main Menu and press Enter. Next, highlight BOOTP/DHCP Relay on the Switch Utilities menu and press Enter.

Figure 6-85. BOOTP/DHCP Relay menu

The following fields can be set:

ParameterDescription

BOOTP/DHCP

Relay Status <Disabled>

This field can be toggled between Enabled and Disabled using the space bar. It is used to enable or disable the BOOTP/DHCP Relay service on the switch. The default is Disabled.

BOOTP HOPS Count Limit [4 ]

This field allows an entry between 1 and 16 to define the maximum number of router hops BOOTP messages can be forwarded across. The default hop count is 4.

BOOTP/DHCP

Relay Time

Threshold:[0 ]

Allows an entry between 0 and 65535 seconds, and defines the maximum time limit for routing a BOOTP/DHCP packet. If a value of 0 is entered, the switch will not process the value in the seconds field of the BOOTP or DHCP packet. If a non-zero value is entered, the switch will use that value, along with the hop count to determine whether to forward a given BOOTP or DHCP packet.
