DNS server configuration
A DNS server manages the host names for a fabric. This enables you to specify servers and switches by a
meaningful name rather than IP address. To configure a DNS server, enter the set setup system dns
command in an Admin session, as shown in the following example:
8/20q FC Switch (admin) #> set setup system dns
A list of attributes with formatting and current values will follow.
Enter a new value or simply press the ENTER key to accept the current value.
If you wish to terminate this process before reaching the end of the list
press 'q' or 'Q' and the ENTER key to do so.
Current Values:
DNSClientEnabled False
DNSLocalHostname <undefined>
DNSServerDiscovery Static
DNSServer1Address <undefined>
DNSServer2Address <undefined>
DNSServer3Address <undefined>
DNSSearchListDiscovery Static
DNSSearchList1 <undefined>
DNSSearchList2 <undefined>
DNSSearchList3 <undefined>
DNSSearchList4 <undefined>
DNSSearchList5 <undefined>
New Value (press ENTER to accept current value, 'q' to quit, 'n' for none):
DNSClientEnabled (True / False) :
DNSLocalHostname (hostname) :
DNSServerDiscovery (1=Static, 2=Dhcp, 3=Dhcpv6) :
DNSServer1Address (IPv4, or IPv6 Address) :
DNSServer2Address (IPv4, or IPv6 Address) :
DNSServer3Address (IPv4, or IPv6 Address) :
DNSSearchListDiscovery (1=Static, 2=Dhcp, 3=Dhcpv6) :
DNSSearchList1 (domain name) :
DNSSearchList2 (domain name) :
DNSSearchList3 (domain name) :
DNSSearchList4 (domain name) :

Do you want to save and activate this system setup? (y/n): [n]
Verifying a switch in the network
You can use the ping command to verify that a switch is communicating in the network. The following
example successfully tests the network for a switch with IP address 10.20.11.57.
8/20q FC Switch #> ping 10.20.11.57
Ping command issued. Waiting for response...
8/20q FC Switch #>
Response successfully received from 10.20.11.57.
If the switch was unreachable, you would see the following display:
8/20q FC Switch #> ping 10.20.11.57
Ping command issued. Waiting for response...
No response from 10.20.11.57. Unreachable.
