2.If you have specified hosts using the telnetenable CLI command, make sure the host from which you are attempting to Telnet is on the list.

3.If you are using a DNS server, perform the following step: Configure the system to use a functioning DNS server by entering:

# ip name-server ip-address

where ip-addressis the IP address of the DNS server.

If you are using the import CLI command, proceed to the next step.

4.Verify that the system can get DNS services from the network by entering the following command:

# nslookup dns-name {hostname ip-address}

where dns-nameis the DNS name of a host on the network that is registered in DNS and hostname and ip-addressis the same IP address specified in 2. The command returns the IP address of the host.

5.If the system cannot resolve DNS names to IP addresses, the DNS server it is using is not working properly.

6.If you are using the import CLI command to resolve host names, verify that the WLSE can resolve host names by entering the following command:

ping hostname

where hostname is a host name that has been mapped to an IP address, or imported in a host file, using the import command.

7.If the system can resolve DNS names to IP addresses but you still cannot connect to the system using Telnet, or Telnet interaction with the system is extremely slow, contact Cisco’s Technical Assistance Center.
