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 4-18.)

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 4-5.)

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 “Preferred and Valid Address Lifetimes” on page 3­ 25.)
