Introduction to IPv6 Diagnostic and Troubleshooting Diagnostic and Troubleshooting The software includes the IPv6 diagnostic and troubleshooting features listed in this section. Ping6 Implements the Ping protocol for IPv6 destinations, and includes the same options as are available for IPv4 Ping, including DNS hostnames. Refer to "Ping for IPv6 (Ping6)" on page 7-2. Traceroute6 Implements Traceroute for IPv6 destinations, and includes the same options as are available for the IPv4 Traceroute, including DNS hostnames. Refer to "Traceroute for IPv6" on page 7-5. Debug/Syslog Enhancements Includes new options for IPv6. Refer to "Debug/Syslog for IPv6" on page 7-11. Domain Name System (DNS) Resolution This feature enables resolving a host name to an IPv6 address and the reverse, and takes on added importance over its IPv4 counterpart due to the extended length of IPv6 addresses. With DNS-compatible commands, CLI command entry becomes easier for reaching a device whose IPv6 address is configured with a host name counterpart on a DNS server. The software includes the following DNS-compatible commands: ■ ping6 ■ traceroute6 The switches covered by this guide now support a prioritized list of up to three DNS server addresses. (Earlier software releases supported only one DNS server address.) Also, the server address list can include both IPv4 and IPv6 DNS server addresses. (An IPv6 DNS server can respond to IPv4 queries, and the reverse.) 2-13
