Configuring Name Resolution

Configuring Name Resolution

The WLSE resolves host names by using a Domain Name System (DNS) server, or you can use the import CLI command to add individual hosts or a UNIX-style hosts file. For information on this command, see User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.7.

If you are using a DNS server, register the WLSE on the DNS server, using the WLSE’s host name as its DNS name.

Configuring the WLSE Without a DNS Server

The WLSE does not require name resolution, but if name resolution is not used, the following problems will occur:

Host names will not resolve.

Discovery will be slow.

Connecting to the WLSE via Telnet will be slow. You will be able to connect to the WLSE only after name resolution on the client times out.

Ping and traceroute commands will result in 100% packet losses in 4 out of 5 ICMP packets. This occurs because the WLSE times out when attempting reverse DNS lookup.

IP addresses will appear instead of hostnames in WLSE displays.

You will not be able to download access point firmware directly from Cisco.com to the WLSE.

If you are not using a DNS server, perform the steps described in Configuring the WLSE’s Network Information, page 4-2, with the following exception:

Step 1 At the DNS server ip address prompt, enter any IP address.

Step 2 After you finish configuring the WLSE, erase the IP address you entered by entering the following command:

no ip name-server ip-address
