Introduction to IPv6
Diagnostic and Troubleshooting
Caution 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 same
options as are available for the IPv4 Traceroute, including DNS hostnames.
Refer to “Traceroute for IPv6” on page 8-6.
