After these commands are entered, when the user logs on, the MOTD banner is displayed, followed by the text Do you agree? If the user enters y, then the login proceeds; if not, then the user is disconnected.

Configuring and You can configure a WX switch to use a Domain Name Service (DNS)

Managing DNS server to resolve hostnames into their IP addresses. This capability is useful in cases where you specify a hostname instead of an IP address in a command.

For example, as an alternative to the command ping 192.168.9.1, you can enter the command ping chris.example.com. When you enter ping chris.example.com, the WX switch's DNS client queries a DNS server for the IP address that corresponds to the hostname chris.example.com, then sends the ping request to that IP address.

The WX switch’s DNS client is disabled by default. To configure DNS:

Enable the DNS client.

Specify the IP addresses of the DNS servers.

Configure a default domain name for DNS queries.

Enabling or Disabling The DNS client is disabled by default. To enable or disable the DNS client, the DNS Client use the following command:

set ip dns {enable disable}

Configuring DNS You can configure a WX switch to use one primary DNS server and up to Servers five secondary DNS servers to resolve DNS queries.

The WX switch always sends a request to the primary DNS server first. The WX switch sends a request to a secondary DNS server only if the primary DNS server does not respond.

To add a DNS server, use the following command:

set ip dns server ip-addr{primary secondary}

Removing a DNS Server

To remove a DNS server, use the following command:

clear ip dns server ip-addr
