Setting the Switch’s IP Address (IP Version 6)
– 441 –
Parameters
These parameters are displayed:
◆ VLAN – ID of a configured VLAN which is to be used for management access. 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)
◆ Address Type – Defines the address type configured for this interface.
â– 
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).
â– 
EUI-64 (Extended Universal Identifier) – Configures an IPv6 address for an
interface using an EUI-64 interface ID in the low order 64 bits.
â– 
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.
â– 
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 6-byte MAC address (also
known as EUI-48 format), it must be converted into EUI-64 format by
inverting the universal/local bit in the address and inserting the
hexadecimal number FFFE between the upper and lower three bytes of
the MAC address.
For example, if a device had an EUI-48 address of 28-9F-18-1C-82-35,
the global/local bit must first be inverted to meet EUI-64 requirements
(i.e., 1 for globally defined addresses and 0 for locally defined
addresses), changing 28 to 2A. Then the two bytes FFFE are inserted
between the OUI (i.e., organizationally unique identifier, or company
identifier) and the rest of the address, resulting in a modified EUI-64
interface identifier of 2A-9F-18-FF-FE-1C-82-35.
â– 
This host addressing method allows the same interface identifier to be
used on multiple IP interfaces of a single device, as long as those
interfaces are attached to different subnets.
