•
Dynamic address allocation, where the server chooses and allocates an IP
address with a finite lease. By default, the EtherXtend will attempt to
assign the same address (if available) to a device on lease renewal. This
default can be changed to force a new address to be assigned.
•
Static address allocation, where the server allocates the same IP address
every time a device connects to the network.

External DHCP server
Setting global DHCP server options
At startup, the EtherXtend creates a default dhcp-server-options record. This
profile defines global options for the EtherXtend DHCP server.
The following example shows the dhcp-server-options profile with its
default values:
zSH> get dhcp-server-options 0
Please provide the following: [q]uit.
lease-time: -----> {43200}:
min-lease-time: -> {0}:
max-lease-time: -> {86400}:
reserve-start: --> {5}:
reserve-end: ----> {5}:
restart: --------> {no}:
....................
The dhcp-server-options profile supports the following parameters (all
others should be left at their default values):
Parameter
Description
lease-time
The global default time in seconds that
will be assigned to a DHCP lease if the
client requesting the lease does not
request a specific expiration time.
min-lease-time
The minimum expiration time in
seconds that will be assigned to a
DHCP lease by the server, regardless
of the value specified by a client.
Values:
