Dhcp Server - Proxim AP-4000 User Manual

Performing Advanced Configuration
Network
DNS Client
If you prefer to use host names to identify network servers rather than IP addresses, you can configure the AP to act as a Domain Name
Service (DNS) client. When this feature is enabled, the Access Point contacts the network's DNS server to translate a host name to the
appropriate network IP address. You can use this DNS Client functionality to identify RADIUS servers by host name.
• Enable DNS Client: Place a check mark in the box provided to enable DNS client functionality. Note that this option must be enabled
before you can configure the other DNS Client parameters.
• DNS Primary Server IP Address: The IP address of the network's primary DNS server.
• DNS Secondary Server IP Address: The IP address of a second DNS server on the network. The Access Point will attempt to contact
the secondary server if the primary server is unavailable.
• DNS Client Default Domain Name: The default domain name for the Access Point's network (for example, "proxim.com"). Contact your
network administrator if you need assistance setting this parameter.
Advanced
• Default TTL (Time to Live): Time to Live (TTL) is a field in an IP packet that specifies how long in seconds the packet can remain active
on the network. The Access Point uses the default TTL for packets it generates for which the transport layer protocol does not specify a
TTL value. This parameter supports a range from 0 to 255. By default, TTL is 64.

DHCP Server

If your network does not have a DHCP Server, you can configure the AP as a DHCP server to assign dynamic IP addresses to Ethernet
nodes and wireless clients.
CAUTION
!
Make sure there are no other DHCP servers on the network and do not enable the DHCP server without checking with your network
administrator first, as it could disrupt normal network operation. Also, the AP must be configured with a static IP address before
enabling this feature.
When the DHCP Server functionality is enabled, you can create one or more IP address pools from which to assign addresses to network
devices.
