Setting the Switch’s IP Address (IP Version 6)

• ND Reachable Time – The amount of time that a remote IPv6 node is considered reachable
after some reachability confirmation event has occurred. (Range: 0-3600000 milliseconds;
Default: 30000 milliseconds)
• Restart DHCPv6 – When DHCPv6 is restarted, the switch may attempt to acquire an IP address
prefix through stateful address autoconfiguration. If the router advertisements have the “other
stateful configuration” flag set, the switch may also attempt to acquire other non-address
configuration information (such as a default gateway) when DHCPv6 is restarted.
Prior to submitting a client request to a DHCPv6 server, the switch should be configured with a
link-local address using the Address Autoconfig option. The state of the Managed Address
Configuration flag (M flag) and Other Stateful Configuration flag (O flag) received in Router
Advertisement messages will determine the information this switch should attempt to acquire
from the DHCPv6 server as described below.
• Both M and O flags are set to 1:
DHCPv6 is used for both address and other configuration settings.
This combination is known as DHCPv6 stateful autoconfiguration, in which a DHCPv6
server assigns stateful addresses to IPv6 hosts.
• The M flag is set to 0, and the O flag is set to 1:
DHCPv6 is used only for other configuration settings.
Neighboring routers are configured to advertise non-link-local address prefixes from which
IPv6 hosts derive stateless addresses.
This combination is known as DHCPv6 stateless autoconfiguration, in which a DHCPv6
server does not assign stateful addresses to IPv6 hosts, but does assign stateless
configuration settings.
Interface
To general IPv6 settings for the switch:
1. Click IP, IPv6 Configuration.
2. Select Configure Interface from the Action list.
3. Specify the VLAN to configure, enable address auto-configuration, or enable IPv6 explicitly to
automatically configure a link-local address and enable IPv6 on the selected interface. Set the
MTU size, the maximum number of duplicate address detection messages, the neighbor
solicitation message interval, and the remote node reachable time.
4. Click Apply.
