Chapter 15 | IP Configuration
Setting the Switch’s IP Address (IP Version 6)
– 608 –
■
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.
RA Guard Mode
◆ Interface – Shows port or trunk configuration page.
◆ RA Guard – Blocks incoming Router Advertisement and Router Redirect
packets. (Default: Disabled)
IPv6 Router Advertisements (RA) convey information that enables nodes to
auto-configure on the network. This information may include the default router
address taken from the observed source address of the RA message, as well as
on-link prefix information. However, note that unintended misconfigurations,
or possibly malicious attacks on the network, may lead to bogus RAs being
sent, which in turn can cause operational problems for hosts on the network.
RA Guard can be used to block RAs and Router Redirect (RR) messages on the
specified interface. Determine which interfaces are connected to known
routers, and enable RA Guard on all other untrusted interfaces.
Web Interface
To configure general IPv6 settings for the switch:
1. Click IP, IPv6 Configuration.
2. Select Configure Interface from the Action list.
3. Select VLAN mode.
4. Specify the VLAN to configure.
5. Enable address auto-configuration, or enable IPv6 Explicitly to automatically
configure a link-local address and enable IPv6 on the selected interface. (To
manually configure the link-local address, use the Add IPv6 Address page.) Set
the MTU size, the maximum number of duplicate address detection messages,
the neighbor solicitation message interval, and the amount of time that a
remote IPv6 node is considered reachable.
6. Click Apply.
