3 Configuring the Switch

Displaying Address Bindings

You can display the host devices which have acquired an IP address from this switch’s DHCP server.

Command Attributes

•IP Address – IP address assigned to host.

•Mac Address – MAC address of host.

•Lease time – Duration that this IP address can be used by the host.

•Start time – Time this address was assigned by the switch.

•Delete – Clears this binding to the host. This command is normally used after modifying the address pool, or after moving DHCP service to another device.

•Entry Count – Number of hosts that have been given addresses by the switch.

Note: More than one DHCP server may respond to a service request by a host. In this case, the host generally accepts the first address assigned by any DHCP server.

Web – Click DHCP, Server, IP Binding. You may use the Delete button to clear an address from the DHCP server’s database.
