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.
