HAPTER
17 | IP Configuration
Setting the Switch’s IP Address (IP Version 6)
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 in the web interface:
◆
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).
■
EUI-64 (Extended Universal Identifier) – Configures an IPv6
address for an interface using an EUI-64 interface ID in the low
order 64 bits.
■
When using EUI-64 format for the low-order 64 bits in the host
portion of the address, the value entered in the IPv6 Address
field includes the network portion of the address, and the prefix
length indicates how many contiguous bits (starting at the left)
of the address comprise the prefix (i.e., the network portion of
the address). Note that the value specified in the IPv6 Address
field may include some of the high-order host bits if the
specified prefix length is less than 64 bits. If the specified prefix
length exceeds 64 bits, then the bits used in the network portion
of the address will take precedence over the interface identifier.
■
IPv6 addresses are 16 bytes long, of which the bottom 8 bytes
typically form a unique host identifier based on the device’s MAC
address. The EUI-64 specification is designed for devices that
use an extended 8-byte MAC address. For devices that still use a
