LABEL DESCRIPTION

Interface Select the IPv6 interface you want to configure.

DAD Attempts The Switch uses Duplicate Address Detection (DAD) with neighbor solicitation and advertisement

messages to check whether an IPv6 address is already in use before assigning it to an interface,

such as the link-local address it creates through stateless address autoconfiguration.

Specify the number of consecutive neighbor solicitations (from 0 to 600) the Switch sends for this

interface. Enter 0 to turn off DAD.

NS Interval Specify the time interval (from 1000 to 3600000 milliseconds) at which neighbor solicitations are re-

sent for this interface.

Reachable

Time

Specify how long (from 1000 to 3600000 milliseconds) a neighbor is considered reachable for this

interface.

Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these

changes if it is turned off or loses power, so use the Save link on the top navigation panel to save

your changes to the nonvolatile memory when you are done configuring.

Cancel Click Cancel to begin configuring this screen afresh.
