C HAPTER 16 | IP Configuration
Setting the Switch’s IP Address (IP Version 6)
– 697 –
CONFIGURING IPV6
INTERFACE SETTINGS
Use the IP > IPv6 Configuration (Configure Interface) page to configure
general IPv6 settings for the selected VLAN, including explicit configuration
of a link local interface address, the MTU size, and neighbor discovery
protocol settings for duplicate address detection and the neighbor
solicitation interval.
CLI REFERENCES
◆ "IPv6 Interface" on page 1663
◆ "DHCP Client" on page 1625
COMMAND USAGE
◆ The switch must be configured with a link-local address. The option to
explicitly enable IPv6 creates a link-local address, but will not generate
a global IPv6 address. The global unicast address must be manually
configured (see "Configuring an IPv6 Address" on page 700).
◆ IPv6 Neighbor Discovery Protocol supersedes IPv4 Address Resolution
Protocol in IPv6 networks. IPv6 nodes on the same network segment
use Neighbor Discovery to discover each other's presence, to determine
each other's link-layer addresses, to find routers and to maintain
reachability information about the paths to active neighbors. The key
parameters used to facilitate this process are the number of attempts
made to verify whether or not a duplicate address exists on the same
network segment, and the interval between neighbor solicitations used
to verify reachability information.
PARAMETERS
These parameters are displayed:
VLAN Mode
◆ VLAN – ID of a configured VLAN which is to be used for management
access, or as a standard interface for a subnet. By default, all ports on
the switch are members of VLAN 1. However, the management station
can be attached to a port belonging to any VLAN, as long as that VLAN
has been assigned an IP address. (Range: 1-4094)
◆ Enable IPv6 Explicitly – Enables IPv6 on an interface and assigns it a
link-local address. Note that when an explicit address is assigned to an
interface, IPv6 is automatically enabled, and cannot be disabled until all
assigned addresses have been removed. (Default: Disabled)
Disabling this parameter does not disable IPv6 for an interface that has
been explicitly configured with an IPv6 address.
◆ MTU – Sets the size of the maximum transmission unit (MTU) for IPv6
packets sent on an interface. (Range: 1280-65535 bytes;
Default: 1500 bytes)
■
The maximum value set in this field cannot exceed the MTU of the
physical interface, which is currently fixed at 1500 bytes.
■
If a non-default value is configured, an MTU option is included in the
router advertisements sent from this device. This option is provided
to ensure that all nodes on a link use the same MTU value in cases
where the link MTU is not otherwise well known.
