Setting the Switch’s IP Address (IP Version 6)
– 583 –
◆
The switch must always be configured with a link-local address.
Therefore, explicitly enabling IPv6 (see
) or manually assigning a global unicast address
will also automatically generate a link-local unicast address. The prefix
length for a link-local address is fixed at 64 bits, and the host portion of
the default address is based on the modified EUI-64 (Extended
Universal Identifier) form of the interface identifier (i.e., the physical
MAC address). Alternatively, you can manually configure the link-local
address by entering the full address with a network prefix in the range
of FE80~FEBF.
◆
To connect to a larger network with multiple subnets, you must
configure a global unicast address. There are several alternatives to
configuring this address type:
■
It can be manually configured by specifying the entire network
prefix and prefix length, and using the EUI-64 form of the interface
identifier to automatically create the low-order 64 bits in the host
portion of the address.
■
You can also manually configure the global unicast address by
entering the full address and prefix length.
◆
You can configure multiple IPv6 global unicast addresses per interface,
but only one link-local address per interface.
◆
If a duplicate link-local address is detected on the local segment, this
interface is disabled and a warning message displayed on the console.
If a duplicate global unicast address is detected on the network, the
address is disabled on this interface and a warning message displayed
on the console.
◆
When an explicit address is assigned to an interface, IPv6 is
automatically enabled, and cannot be disabled until all assigned
addresses have been removed.
P
ARAMETERS
These parameters are displayed:
◆
VLAN – ID of a configured VLAN which is to be used for management
access, or for creating an interface to multiple subnets. 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: 1-4093)
◆
Address Type – Defines the address type configured for this interface.
■
Global – Configures an IPv6 global unicast address with a full IPv6
address including the network prefix and host address bits, followed
by a forward slash, and a decimal value indicating how many
contiguous bits (from the left) of the address comprise the prefix
(i.e., the network portion of the address).
