IPv6 Addressing Configuration
View the Current IPv6 Addressing Configuration
■
DAD Attempts:
Indicates the number of neighbor solicita-
tions the switch transmits per-address for duplicate
(IPv6) address detection. Implemented when a new
address is configured or when an interface with config-
ured addresses comes up (such as after a reboot). The
default setting is 3, and the range is 0 - 600. A setting of
“0” disables duplicate address detection. (Refer to “Dupli-
cate Address Detection (DAD)” on page 1-14.)
■
VLAN Name:
Lists the name of a VLAN statically configured
on the switch.
■
IPv6 Status:
For the indicated VLAN, indicates whether
IPv6 is disabled (the default) or enabled. (Refer to “Config-
uring IPv6 Addressing” on page 1-3.)
■
IPv6 Address/Prefix Length:
Lists each IPv6 address and
prefix length configured on the indicated VLAN.
■
Expiry:
Lists the lifetime status of each IPv6 address listed
for a VLAN:
• Permanent:
The address will not time out and need
renewal or replacement.
•
date/time:
The date and time that the address expires.
Expiration date and time is specified in the router
advertisement used to create the prefix for automati-
cally configured, global unicast addresses. The
Address
Status
field in the
show ipv6
command output indicates
whether this date/time is for the “preferred” or “valid”
lifetime assigned to the corresponding address. (Refer
to “Router Access and Default Router Selection” on
page 1-23.
