DNS MANAGEMENT
OVERRIDING DYNAMICALLY ASSIGNED DNS SERVERS
If required, you can override the DNS servers dynamically assigned by PPPoE or DHCP as follows:
1. In the management tool, click
Network, then click DNS. The DNS configuration page opens.
2. Specify the addresses of Server 1 and Server 2.
3. Click Save when you are done.
DNS SERVER PARAMETERS
Server 1
Specify the IP address of the first DNS server that the LPS-20x will use.
Server 2
Specify the IP address of the second DNS server that the LPS-20x will use.
DNS cache
Enables the DNS cache. Once the host name has been successfully resolved to an IP address by a remote DNS
server, it is stored in the cache. This speeds up network performance as the remote DNS server now does not have
to be queried for subsequent requests for this host.
The entry stays in the cache until:
• an error occurs when connecting to the remote host
• the time to live (TTL) of the DNS request expires
• the LPS-20x is restarted
SETTING UP A MULTI-CELL WIRELESS NETWORK
Multiple LPS-20xs are installed in conjunction with a RADIUS Server to provide multiple wireless cells for coverage
of large locations. Client computers are able to move between cells (called roaming) without losing contact with the
network. This is possible because wireless adapters automatically switch to the best available wireless access point.
