14.5.2DHCP Troubleshooting Help

If the DHCP clients cannot obtain IP addresses and other network parameters, the following procedures can be followed after DHCP client hardware and cables have been verified to be ok.

&Verify the DHCP server is running, start the related DHCP server if not running.

&If the DHCP clients and servers are not in the same physical network, verify that the router responsible for DHCP packet forwarding has DHCP relay function. If DHCP relay is not available for the intermediate router, it is recommended to replace the router or upgrade its software to one that has a DHCP relay function.

&In such case, the DHCP server should be examined for an address pool that is in the same segment of the switch VLAN, such a pool should be added if not present. (This does not indicate ES4710BD cannot assign IP address for different segments, see solution 2 for details.)

&If in DHCP service, pools for dynamic IP allocation and manual binding are conflicting, i.e., if command “network-address” and “host” are run for a pool, then only one of them will take effect; furthermore, in manual binding, only one IP-MAC binding can be configured in a pool. If multiple bindings are required, multiple manual pools can be created and IP-MAC bindings set for each pool. New configuration in the same pool will overwrite the previous configuration.

14.6.1DHCP server configuration

Click “DHCP configuration”, to open switch DHCP function configuration management list. User may make switch DHCP function configurations

14.6.2Enable DHCP

Click “DHCP configuration”, “DHCP server configuration”, Enable DHCP. You may configure enable or disable the DHCP server, configure address collision log server function, and more

zDHCP server status - enables, disables the DHCP server function. This is the same as CLI command 14.2.2.19)

zConflict logging status - enables, disables the DHCP server checking address conflict log function. This is the same as CLI command 14.2.2.9

zLogging server(optional) – assign a DHCP logging server IP address. This is the same as CLI command 14.2.2.12

zLogging server port (optional,1-65535) – assign a DHCP logging server port ID

Example: Choose DHCP server status as open, choose Conflict logging status as open, configure Logging server as 10.0.0.1, configure Logging server port as 45, click Apply button, to apply the configuration to switch..
