Address Binding
Use the Address Binding page to view and remove the IP addresses allocated by
the device and their corresponding MAC addresses.
To view and/or remove address bindings:
STEP 1 Click IP Configuration > IPv4 Management and Interfaces > DHCP Server >
Address Binding to display the Address Binding page.
The following fields for the address bindings are displayed:
• IP Address—The IP addresses of the DHCP clients.
• Address Type— Whether the address of the DHCP client appears as a MAC
address or using a client identifier.
• MAC Address/Client Identifier—A unique identification of the client
specified as a MAC Address or in hexadecimal notation, e.g.,
01b60819681172.
• Lease Expiration—The lease expiration date and time of the host’s IP
address or Infinite is such was the lease duration defined.
• Typ e—The manner in which the IP address was assigned to the client. The
possible options are:
- Static—The hardware address of the host was mapped to an IP address.
- Dynamic—The IP address, obtained dynamically from the device, is
owned by the client for a specified period of time. The IP address is
revoked at the end of this period, at which time the client must request
another IP address.
• State—The possible options are:
- Allocated—IP address has been allocated. When a static-host is
configured, its state is allocated.
- Declined—IP address was offered but not accepted, therefore it is not
allocated.
- Expired—The lease of the IP address has expired.
- Pre-Allocated—An entry will be in pre-allocated state from the time
between the offer and the time that the DHCP ACK is sent from the client.
Then it becomes allocated.
