Chapter 8 Basic Setting Table 19 Basic Setting > IPv6 > IPv6 Interface Status (continued) LABEL Global Unicast Address(es) Joined Group Address(es) ND DAD Active Number of DAD Attempts NS-Interval (millisecond) ND Reachable Time (millisecond) DHCPv6 Client Active Identity Association IA Type IAID T1 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. This field displays whether Neighbor Discovery (ND) Duplicate Address Detection (DAD) is enabled on the interface. This field displays the number of consecutive neighbor solicitations the Switch sends for this interface. This field displays the time interval (in milliseconds) at which neighbor solicitations are resent for this interface. This field displays how long (in milliseconds) a neighbor is considered reachable for this interface. This field displays whether the Switch acts as a DHCPv6 client to get an IPv6 address from a DHCPv6 server. 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. 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. T2 State 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. SID Address Preferred Lifetime Valid Lifetime DNS Domain List Restart DHCPv6 Client Rebind when the Switch doesn't 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.
