bound host address pools (that is, one address per host pool) can be
configured.
• When a client request is received, the ECN330-switch first checks for a
network address pool matching the gateway where the request
originated (that is, if the request was forwarded by a relay server). If
there is no gateway in the client request (that is, the request was not
forwarded by a relay server), the ECN330-switch searches for a network
pool matching the interface through which the client request was
received. It then searches for a manually configured host address that
falls within the matching network pool. If no manually configured host
address is 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 ECN330-switch compares
the client identifier and then the hardware address for DHCP clients.
Since BOOTP clients cannot transmit a client identifier, a hardware
address must be configured for this host type. If no manual binding has
been specified for a host entry with a hardware address or client
identifier, the ECN330-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 page 428). The DHCP server
assumes that all host addresses are available. Subsets of the address
space can be excluded by using the IP Excluded Address field on the
DHCP Server General configuration page.
