Command Usage
•
All IPv6 addresses must be formatted according to RFC 2373 "IPv6 Addressing
Architecture," using 8 colon-separated 16-bit hexadecimal values. One double colon
may be used in the address to indicate the appropriate number of zeros required to
fill the undefined fields.
•
The switch must always be configured with a link-local address. Therefore any
configuration process that enables IPv6 functionality, or assigns a global unicast
address to the switch, including address auto-configuration or explicitly enabling
IPv6 (see
"Configuring IPv6 Interface Settings" on page
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 the network prefix FE80.
•
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:
•
The global unicast address can be automatically configured by taking the
network prefix from router advertisements observed on the local interface, and
using the modified EUI-64 form of the interface identifier to automatically create
the host portion of the address (see
page
16-9).
•
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.
Parameters
These parameters are displayed in the web interface:
•
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: 1-4093)
•
Address Type – Defines the address type configured for this interface.
