IPv6 Diagnostic and Troubleshooting DNS Resolver for IPv6 Note DNS Resolver for IPv6 The Domain Name System (DNS) resolver is designed for local network domains where it enables use of a host name or fully qualified domain name to support DNS-compatible commands from the switch. DNS operation supports these features: ■ dual-stack operation: IPv6 and IPv4 DNS resolution ■ DNS-compatible commands: ping, ping6, traceroute, and traceroute6 ■ multiple, prioritized DNS servers (IPv4 and IPv6) DNS Configuration Up to three DNS servers can be configured. The addresses must be prioritized, and can be for any combination of IPv4 and IPv6 DNS servers. This section describes the commands for configuring DNS operation for IPv6 DNS applications. For further information and examples on using the DNS feature, refer to "DNS Resolver" in appendix C, "Troubleshooting", in the current Management and Configuration Guide for your switch. Syntax:. [no] ip dns server-address priority < 1 - 3 > < ip-addr > [oobm] Used at the global config level to configure the address and priority of a DNS server. Allows for configuring up to three servers providing DNS service. (The servers must all be acces sible to the switch.) The command allows both IPv4 and IPv6 servers in any combination and any order of priority. priority < 1 - 3 >: Identifies the order in which the specified DNS server will be accessed by a DNS resolution attempt. A resolu tion attempt tries each configured DNS server address, in ascending order of priority, until the attempt is successful or all configured server options have been tried and failed. To change the priority of an existing server option, you must remove the option from the switch configuration and re-enter it with the new priority. If another server address is config ured for the new priority, you must also remove that address from the configuration before re-assigning its priority to another address. - Continued on the next page. - 7-8
