DNS Server Table:
• DNS Server—The IP addresses of the DNS servers. Up to eight DNS servers
can be defined.
• Server State—The DNS server state can be either active or inactive. There
can be only one active server. Each static server has a priority, a lower value
means a higher priority. When first time the request is sent, static server with
lowest priority is chosen. If after two retries there is no response from this
server, the next server with the next lowest priority is selected. If none of the
static servers respond, the first dynamic server on the table, sorted by IP
address (low to high), is selected.
Click Apply. The Running Configuration file is updated.
To add a DNS server, click Add. The Add DNS Server page opens.
Enter the parameters.
• IP Version—Select Version 6 for IPv6 or Version 4 for IPv4.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The
options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
• Link Local Interface—If the IPv6 address type is Link Local, select whether
it is received through VLAN2 or ISATAP.
• DNS Server IP Address—Enter the DNS server IP address.
• Set DNS Server Active—Select to activate the new DNS server.
Click Apply. The DNS server is written to the Running Configuration file.
