Software User Manual 12/10/09 D-Link Unified Access System Figure 107: DHCP L2 Relay Global Configuration If you enable or disable this feature, click Submit to apply the changes to system. DHCP L2 Relay Interface Configuration Use this page to enable L2 DHCP relay on individual ports. Note that L2 DHCP relay must also be enabled globally on the switch. To access this page, click LAN > L2 Features > DHCP Snooping > DHCP L2 Relay > Interface Configuration. Figure 108: DHCP L2 Relay Interface Configuration Table 93: DHCP L2 Relay Interface Configuration Field Slot/Port DHCP L2 Relay Mode DHCP L2 Relay Trust Mode Description Select the slot/port to configure this feature on. Enable or disable L2 Relay mode on the selected interface. Enable or disable L2 Relay Trust Mode on the selected interface. Trusted interfaces usually connect to other agents or servers participating in the DHCP interaction (e.g. other L2 or L3 Relay Agents or Servers). When enabled in Trust Mode, the interface always expects to receive DHCP packets that include Option 82 information. If Option 82 information is not included, then these packets are discarded. Untrusted interfaces are generally connected to clients. DHCP packets arriving on an untrusted interface are never expected to carry Option 82 and are discarded if they do. If you change any settings on this page, click Submit to apply the changes to system. Document 34CSFP6XXUWS-SWUM100-D7 Configuring DHCP Snooping Page 183
