Chapter 13 Interfaces
UAG CLI Reference Guide

This example shows how to restart an interface. You can check all interface names on the UAG.
Then use either the system name or user-defined name of an interface (ge4 or Customer in this
example) to restart it.
13.2.2 DHCP Setting Commands
This table lists DHCP setting commands. DHCP is based on DHCP pools. Create a DHCP pool if you
want to assign a static IP address to a MAC address or if you want to specify the starting IP address
and pool size of a range of IP addresses that can be assigned to DHCP clients. There are different
commands for each configuration. Afterwards, in either case, you have to bind the DHCP pool to the
interface.

[no] ip dhcp pool profile_name
Creates a DHCP pool if necessary and enters sub-command mode.
You can use the DHCP pool to create a static entry or to set up a
range of IP addresses to assign dynamically.
About the sub-command settings:
• If you use the
host
command, the UAG treats this DHCP pool as a
static DHCP entry.
• If you do not use the
host
command and use the
network
command, the UAG treats this DHCP pool as a pool of IP
addresses.
• If you do not use the
host
command or the
network
command,
the DHCP pool is not properly configured and cannot be bound to
any interface.
The
no
command removes the specified DHCP pool.
show
Shows information about the specified DHCP pool.
Use the following commands to create a static DHCP entry. If you do
not use the
host
command, the commands that are not in this
section have no effect, but you can still set them.
