A Field Office Example
He also selects the option This interface is a DHCP server. Choosing this DHCP
option means that the switch will pick IP addresses from the Address Assignment
Range and assign them to network clients on this subnet, as needed.
This screen also sets the IP address for the switch’s interface to the subnet. Any address that
starts with “192.168” is an internal-use-only IP address. That is, network administrators are
free to use these IP addresses anyway they want, as long as the IP addresses are never
visible to the outside world. The switch defaults to an address of 192.168.0.1 for the first
subnet interface. Leo elects to use the range of IP addresses from 192.168.0.11 to
192.168.0.254 for the DHCP clients in this subnet.
Leo then selects the Advanced DHCP Server button. The DNS server IP addresses and
the Gateway IP address entered here will be passed down the DHCP clients for this subnet
for their own use while associated with this subnet. Leo enters the IP addresses that the
corporation’s IT department has specified for the corporate primary and secondary DNS
servers. For the gateway, Leo enters the IP address for the subnet, the same IP address that
he entered for the IP Address
in the IP Parameters section of the Subnet screen.
The DHCP Least Time field specifies how long a client may keep an IP address when
that client is not active on the net. The lease time is currently set for 10000 seconds or a
little less than three hours. Leo expects that people using these WLANs will connect for a
work day or not. While in the office, he expects that their machines will initiate contact with
the network every 10 or 15 minutes for email. When they unplug to go home, this lease time
will hold their IP address for another three hours and then return it to the pool for tomorrow.
The lease time of somewhere between 10000 seconds and 30000 seconds is appropriate for
this application. Leo leaves it at 10000 seconds.
