found, it assigns an address from the matching network address pool. However,
if no matching address pool is found the request is ignored.
When searching for a manual binding, the switch compares the client identifier
and then the hardware address for DHCP clients. Since BOOTP clients cannot
transmit a client identifier, you must configure a hardware address for this host
type. If no manual binding has been specified for a host entry with a hardware
address or client identifier, the switch will assign an address from the first
matching network pool.
If the subnet mask is not specified for network or host address pools, the class
A, B, or C natural mask is used (see “Specifying Network Interfaces” on
page 703). The DHCP server assumes that all host addresses are available. You
can exclude subsets of the address space by using the IP Service > DHCP >
Server (Configure Excluded Addresses – Add) page.
Parameters
These parameters are displayed:
Creating a New Address Pool
Pool Name – A string or integer. (Range: 1-32 characters)
Type – Sets the address pool type to Network or Host.
Setting Parameters for a Network Pool
IP – The IP address of the DHCP address pool.
Subnet Mask – The bit combination that identifies the network (or subnet) and
the host portion of the DHCP address pool.
Setting Parameters for a Static Host
IP – The IP address to assign to the host.
Subnet Mask – Specifies the network mask of the client.
Client-Identifier – A unique designation for the client device, either a text
string (1-15 characters) or hexadecimal value. The information included in the
identifier is based on RFC 2132 Option 60, and must be unique for all clients in
the same administrative domain.
Hardware Address – Specifies the MAC address and protocol used on the
client. (Options: Ethernet, IEEE802, FDDI, None; Default: Ethernet)
Setting Optional Parameters
Default Router – The IP address of the primary and alternate gateway router.
The IP address of the router should be on the same subnet as the client.
