Introduction to IPv6

Diagnostic and Troubleshooting

The Authorized IP Managers feature does not protect against unauthorized station access through a modem or direct connection to the Console (RS-232) port. Also, if an unauthorized station “spoofs” an authorized IP address, then the unauthorized station cannot be blocked by the Authorized IP Managers feature, even if a duplicate IP address condition exists.

To configure authorized IPv6 managers, refer to “Authorized IP Managers for IPv6” on page 6-3.

For related information, refer to:

■RFC 4864, “Local Network Protection for IPv6”.

Diagnostic and Troubleshooting

Software release K.13.01 includes the IPv6 diagnostic and troubleshooting features listed in this section.

ICMP Rate-Limiting

Controlling the frequency of ICMPv6 error messages can help to prevent DoS (Denial- of- Service) attacks. With IPv6 enabled on the switch, you can control the allowable frequency of these messages with ICMPv6 rate-limiting. Refer to “ICMP Rate-Limiting” on page 8-2.

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 8-4.

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 8-6.
