xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual DHCP / BOOTP Relay The BOOTP hops count limit allows the maximum number of hops (routers) that the BOOTP messages can be relayed through to be set. If a packet's hop count is more than the hop count limit, the packet is dropped. The range is between 1 and 16 hops, with a default value of 4. The relay time threshold sets the minimum time (in seconds) that the Switch will wait before forwarding a BOOTREQUEST packet. If the value in the seconds field of the packet is less than the relay time threshold, the packet will be dropped. The range is between 0 and 65,536 seconds, with a default value of 0 seconds. DHCP / BOOTP Relay Information To enable and configure BOOTP or DHCP on the Switch, click Configuration > DHCP/BOOTP Relay > DHCP/BOOTP Relay Global Settings: Figure 6- 151. DHCP/ BOOTP Relay Global Settings window The following fields can be set: Parameter Description BOOTP Relay State This field can be toggled between Enabled and Disabled using the pull-down menu. It is used to enable or disable the BOOTP/DHCP Relay service on the Switch. The default is Disabled BOOTP Relay Hops Count Limit (1-16) 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 Relay Time Threshold (0-65535) 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. 187
