IP Configuration
270
Instruction Manual - NXA-ENET8-POE+
Perform these steps to configure general IPv6 settings for the switch:
1.
Click
System
>
IPv6 Configuration
.
2.
Select
Configure Interface
from the Action list.
3.
Specify the VLAN to configure.
4.
Enable address auto-configuration, or enable IPv6 explicitly to automatically configure a link-local address and enable IPv6
on the selected interface. (To manually configure the link-local address, use the Add IPv6 Address page.) Set the MTU size, the
maximum number of duplicate address detection messages, the neighbor solicitation message interval, and the amount of
time that a remote IPv6 node is considered reachable.
5.
Click
Apply
.
Configuring an IPv6 Address
Use the System > IPv6 Configuration (Add IPv6 Address) page to configure an IPv6 interface for management access over the
network.
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 the
Configuring IPv6 Interface Settings
section on page 268), 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:
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 the
Configuring IPv6 Interface Settings
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.
