To display the page, click LAN > L3 Features > BOOTP/DHCP Relay Agent Configuration in the navigation tree. Figure 198: BOOTP/DHCP Relay Agent Configuration Table 180: BOOTP/DHCP Relay Agent Configuration Fields Field Maximum Hop Count Server IP Address Admin Mode Minimum Wait Time (secs) Circuit ID Option Mode Description Enter the maximum number of hops a client request can take before being discarded. Enter either the IP address of the BOOTP/DHCP server or the IP address of the next BOOTP/DHCP Relay Agent. Note: This configuration is deprecated. Use "Helper IP Interface Configuration" on page 286 to achieve the same functionality. Select Enable or Disable from the dropdown menu. When you select Enable, BOOTP/ DHCP requests are forwarded to the IP address you entered in the Server IP address field. Enter a time in seconds. This value is compared to the time stamp in the client's request packets, which should represent the time since the client was powered up. Packets are only forwarded when the time stamp exceeds the minimum wait time. Select Enable or Disable from the dropdown menu. If you select Enable, the relay agent adds Option 82 header packets to the DHCP Request packets before forwarding them to the server, and strips them off while forwarding the responses to the client. • If you make any changes to the page, click Submit to apply the changes to the system.
