This field displays whether the Switch acts as a DHCPv6 client to get an IPv6 address from a DHCPv6 server.
Identity Association
An Identity Association (IA) is a collection of addresses assigned to a DHCP client, through which the server and
client can manage a set of related IP addresses. Each IA must be associated with exactly one interface.

DESCRIPTION
This field displays the Switch's global unicast address to identify this interface.
This field displays the IPv6 multicast addresses of groups the Switch's interface joins.
The IA type is the type of address in the IA. Each IA holds one type of address. IA_NA means an
identity association for non-temporary addresses and IA_TA is an identity association for
temporary addresses.
Each IA consists of a unique IAID and associated IP information.
This field displays the DHCPv6 T1 timer. After T1, the Switch sends the DHCPv6 server a Renew
message.
An IA_NA option contains the T1 and T2 fields, but an IA_TA option does not. The DHCPv6 server
uses T1 and T2 to control the time at which the client contacts with the server to extend the
lifetimes on any addresses in the IA_NA before the lifetimes expire.
This field displays the DHCPv6 T2 timer. If the time T2 is reached and the server does not respond,
the Switch sends a Rebind message to any available server.
This field displays the state of the TA. It shows
Active when the Switch obtains addresses from a DHCpv6 server and the TA is created.
Renew when the TA's address lifetime expires and the Switch sends out a Renew message.
Rebind when the Switch does not receive a response from the original DHCPv6 server and sends
out a Rebind message to another DHCPv6 server.
This field displays the DHCPv6 server's unique ID.
This field displays the Switch's global address which is assigned by the DHCPv6 server.
This field displays how long (in seconds) that the global address remains preferred.
This field displays how long (in seconds) that the global address is valid.
This field displays the DNS server address assigned by the DHCPv6 server.
This field displays the address record when the Switch queries the DNS server to resolve domain
names.
Click Restart to send a new DHCP request to the DHCPv6 server and update the IPv6 address and
DNS information for this interface.
