Chapter 6 Basic Setting

GS3700/XGS3700 Series User’s Guide

ICMPv6 Rate
Limit Error
Interval

This field displays the time period (in milliseconds) during which ICMPv6 error messages of
up to the bucket size can be transmitted. 0 means no limit.

Stateless
Address
Autoconfig

This field displays whether the Switch’s interface can automatically generate a link-local
address via stateless autoconfiguration.

Link Local
Address

This field displays the Switch’s link-local IP address and prefix generated by the interface. It
also shows whether the IP address is preferred, which means it is a valid address and can
be used as a sender or receiver address.

Global Unicast
Address(es)

This field displays the Switch’s global unicast address to identify this interface.

Joined Group
Address(es)

This field displays the IPv6 multicast addresses of groups the Switch’s interface joins.

ND DAD Active

This field displays whether Neighbor Discovery (ND) Duplicate Address Detection (DAD) is
enabled on the interface.

Number of DAD
Attempts

This field displays the number of consecutive neighbor solicitations the Switch sends for this
interface.

NS-Interval
(millisecond)

This field displays the time interval (in milliseconds) at which neighbor solicitations are re-
sent for this interface.

ND Reachable
Time
(millisecond)

This field displays how long (in milliseconds) a neighbor is considered reachable for this
interface.

DHCPv6 Client
Active

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.

IA Type

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.

IAID

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.

State

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 doesn’t receive a response from the original DHCPv6 server

and sends out a Rebind message to another DHCPv6 server.

SID

This field displays the DHCPv6 server’s unique ID.
