> # DNS Server Configuration

> The DNS client on the switch communicates with the DNS server to perform the IP address-name server correspondence.

> The DNS server may be dropped after two attempts because of one of the following reasons:

> - The IP address or the switch name is wrongly configured.
> - The DNS server is not reachable because external reasons (reasons beyond our control).

> Note When accessing a Telnet host, if the DNS server is not reachable (for any reason) the switch login prompt may take a longer time to appear. If so, verify that the DNS server is accurately configured and reachable.
