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-address is 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-name is the DNS name of a host on the network that is registered in DNS and
hostname and ip-address is 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.
Resolve the network DNS problem, then continue.
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.
