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
