Introduction to IPv6
Diagnostic and Troubleshooting
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.)
N o t e If an IPv6 DNS server address is configured on the switch, at least one VLAN
on the switch (and in the path to the DNS server) must be configured with an
IPv6 address.
For information on configuring DNS resolution on the switch, refer to “DNS
Resolver for IPv6” on page 9-10.
IPv6 Neighbor Discovery (ND) Controls
The neighbor discovery feature includes commands for:
■ increasing or decreasing the frequency of Duplicate Address Detection
searches
■ displaying the IPv6 neighbor cache
■ clearing dynamic entries from the neighbor cache
Refer to “Neighbor Discovery (ND) in IPv6” on page 2-9.
Event Log
Messages returning IP addresses now include IPv6 addresses where appli­
cable.
SNMP
When IPv6 is enabled on a VLAN interface, you can manage the switch from
a network management station configured with an IPv6 address. Refer to
“SNMP Management for IPv6” on page 5-24.
Loopback Address
Like the IPv4 loopback address, the IPv6 loopback address (::1) can be used
by the switch to send an IPv6 packet to itself. However, the IPv6 loopback
address is implicit on a VLAN and cannot be statically configured on any
VLAN. Refer to “Loopback Address” on page 3-23.
