Figure 6- 122. DHCP Allocation Table
The DHCP Allocation Table contains the following fields:
IP Address
—Indicates the IP Address allocated by the DHCP server.
MAC Address
—Indicates the MAC Addresses are stored in canonical bit order
to match incoming DHCP requests. To match all incoming requests from host
company devices centrally attached to the server, enter an all zero MAC Address.
Mechanism
—Indicates the server allocates IP Addresses. The DHCP server
supports three mechanisms for IP allocation.
•
Automatic allocation
—Indicates the DHCP server selects a permanent IP
Address from a predefined range when a new client requests configuration.
•
Dynamic allocation
—Indicates the DHCP server allocates an IP Address
for a limited period. During this period, the Address is guaranteed this
allocation, and the Dynamic allocation mechanism attempts to return to the
same network each time the client requests an address.
•
Manual allocation
—Indicates the network administrator assigns an IP
Address to a client.
Note:
The DHCP Address Allocation Edit option supports the Manual allocation mechanism only.
Therefore, if Automatic or Dynamic allocation is defined for a particular DHCP server, its
mechanism value is changed to Manual allocation after editing this server and clicking
in the
Edit window
Host Name
—Indicates the host identity requesting the address.
