The Administration section of theSystem General PageSystem General PageSystem General Page System General Page contains the following fields:
System Name — Indicates the user-defined name of the device. This is a required field.
The field range is 0-159 characters.
Administrator — Indicates the name of the administrator responsible for managing the device. The field
range is 0-159 characters.
Comments — (Optional) The user can add any comments about the device in this field, for example, fill in
the location of the device.
IPv4 Address — Indicates the device’s IPv4 address.
Subnet Mask — Indicates the device’s subnet mask.
Default Gateway — The IP address of a router for remote management of the device. The address must be
entered in the format: xxx.xxx.xxx.xxx. The default value is 0.0.0.0.
Packets are forwarded to the default IP when frames are sent to a remote network via the default gateway. The configured IP address must belong to the same subnet as one of the IP interfaces.
The DHCP Configuration section of theSystem General Page System General Page contains the following fields:
DHCP Configuration — Indicates if the Dynamic Host Configuration Protocol (DHCP) is enabled. Enable — DHCP dynamically assigns IP addresses to devices on a network. With dynamic addressing,
a device can have a different IP address every time it connects to the network. If the DHCP client software is activated, the device immediately begins to query the network for a DHCP server. The device continues to query the network for its IP configuration until it receives a response. If the device and IP address are manually assigned, that address is deleted and replaced by the IP address received from the DHCP server.
Disable — Disables DHCP on the device. In this case, the device, following reset, checks if the IP
address is already defined in the Startup Configuration. If not, the device tries to receive an IP address from a BootIP server until either an IP address is received or the user defines the IP address manually.
MAC Address Aging Time — The time interval an inactive dynamic MAC address can remain in the MAC
address table before it is deleted. The default time is 300 seconds, and the range is 10-630.
2. Define the relevant fields.
3. Click Apply. The system general information is defined and the device is updated.
4. Click Save Config on the menu to save the changes permanently.

Configuring IPv6

Chapter 3. Configuring IPv6

The device functions as an IPv6 compliant Host, as well as an IPv4 Host (also known as dual stack). This allows device operation in a pure IPv6 network as well as in a combined IPv4/IPv6 network.
The primary change from IPv4 to IPv6 is the length of network addresses. IPv6 addresses are 128 bits long, whereas IPv4 addresses are 32 bits; allowing a much larger address space.
This section contains information on configuring the Internet Protocol Version 6 (IPv6) of the device.
IPv6 Syntax
The 128-bit IPv6 address format is divided into eight groups of four hexadecimal digits. Abbreviation of this format is done by replacing a group of zeros with double colons. The IPv6 address representation can be further simplified by suppressing the leading zeros.
IPv6 Prefixes
While Unicast IPv6 addresses written with their prefix lengths are permitted, in practice their prefix lengths are always 64 bits and therefore are not required to be expressed. Any prefix that is less than 64 bits is a route or address range that is summarizing a portion of the IPv6 address space.
For every assignment of an IP address to an interface, the system runs the Duplicate Address Detection algorithm to ensure uniqueness.
An intermediary transition mechanism is required for IPv6-only nodes to communicate with IPv6 nodes over an IPv4 infrastructure. The tunneling mechanism implemented is the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP). This protocol treats the IPv4 network as a virtual IPv6 local-link, with each IPv4 address mapped to a Link Local IPv6 address.
This section describes the following topics:
Defining IPv6 Interfaces
Defining the IPv6 Default Gateway
Configuring Tunnels
Defining IPv6 Neighbors

Defining IPv6 Interfaces

The IPv6 Interface Page provides parameters for defining an IPv6 interface. When an interface is selected on a locally connected device, the system creates an IP interface and automatically configures a Link Local address on the interface. The automatically generated Link Local IPv6 address cannot be removed.
In addition to the dynamically configured IPv6 interfaces, there are two types of static IP addresses that can be configured on an IPv6 interface:
Link Local Address — Defines a Link Local address that is non-routable and used for communication on the
same network only.
Global Addresses — Defines a globally unique IPv6 address; visible and reachable from different subnets.
To define IPv6 Interfaces:
1. Click System > IPv6 Interface. The IPv6 Interface Page opens.
Page 25
Allied Telesis AT-S94 Management Software Web Browser Interface User’s Guide
Figure 9: IPv6 Interface Page
The IPv6 Interface Page contains the following fields:
Interface — Indicates the interface on which the IPv6 interface is defined. The possible field values are: VLAN — Indicates the VLAN ID on which IPv6 is enabled. Tunnel1 — Indicates the IPv6 tunnel on which IPv6 is enabled.
DAD Attempts — Defines the number of consecutive neighbor solicitation messages that are sent on an
interface while DAD is performed on Unicast IPv6 addresses on this interface. New addresses remain in a tentative state while duplicate address detection is performed. The range is 0 - 600. A field value of 0, disables duplicate address detection processing on the specified interface. A field value of 1 is the default.
The IPv6 Table on the IPv6 Interface Page displays the IPv6 addresses defined on the Interface. This table contains the following fields:
Delete Button — Deletes the selected IPv6 address. Entries that cannot be removed because they are
generated automatically by the system are unavailable. Only addresses configured by a user can be removed. The possible field values are:
Selected — Removes the selected IPv6 address. Cleared — Maintains the IPv6 address.
IPv6 Type — Defines the type of configurable IPv6 IP address for the interface. The possible values are: Link Local — Defines a Link Local address; non routable and can be used for communication on the
same network only. A Link Local address has a prefix of 'FE80'.
Page 26
Configuring IPv6
Global — Defines a globally unique IPv6 address; visible and reachable from different subnets.
IPv6 Address — Indicates the IPv6 address assigned to the interface.
Prefix — Specifies the length of the IPv6 prefix. The length is a decimal value that indicates how many of the
high-order contiguous bits of the address comprise the prefix (the network portion of the address). The range is 3 -128 (64 in the case EUI-64 parameter is used). The Prefix field is applicable only on a static IPv6 address defined as a Global IPv6 address.
DAD Status — Displays the DAD Status which is the process of verifying and assuring an inserted IPv6
address is unique. This is a read-only parameter with the following field values:
Tentative — Indicates the system is in process of IPv6 address duplication verification. Duplicate — Indicates the IPv6 address is being used by another host on the network. The duplicated
IPv6 address is suspended and is not used for sending or receiving any traffic.
Active — Indicates the IPv6 address is set to active.
2. Select an Interface.
3. Define the DAD Attempts for an existing interface. DAD Attempts are disabled for Tunnel interface. The
range is 0 - 600.
4. Click Apply. The DAD Attempts are defined, and device is updated.
Adding Multiple IPv6 Addresses
The Add IPv6 Address Page allows the user to add multiple IPv6 addresses to an existing IPv6 interface.
1. Click Add. The Add IPv6 Address Page opens.
Figure 10: Add IPv6 Address Page
In addition to the fields in the Add IPv6 Address Page, the Add IPv6 Address Page contains the following field:
EUI-64 — Indicates the interface ID (low-order 64 bits of the IPv6 address) is built from the system base MAC
address. The following fields options are:
Checked — Enables the EUI-64 option. This option is relevant only to Global IPv6 addresses. Unchecked — Disables the EUI-64 option. This is the default value.

2. Select an Interface to map to the IP address.
3. Select an IPv6 Address Type.
4. Define the IPv6 address. Selecting a Global in the IPv6 Address Type requires defining the Prefix Length or selecting the EUI-64 check box.
5. Click Apply. The IPv6 address is mapped to the Interface, and the device is updated.

Configuring IPv6

Defining the IPv6 Default Gateway

The IPv6 Default Gateway Page enables you to configure the IPv6 address of the next hop that can be used to reach the network. Two IPv6 Link-Local address formats are used: standard and one with a specified IPv6 interface identifier. For IPv6, the configuration of the default gateway is not mandatory, as hosts can automatically learn of the existence of a router on the local network via the router advertisement procedure.
Unlike IPv4, the IPv6 default gateway can have multiple IPv6 addresses, which may include only one user-defined static address and multiple dynamic addresses that are learned via router advertised message provided in the IPv6 Default Gateway configuration. The user-defined default gateway has a higher precedence over automatically advertised addresses. It should be noted that configuring a new static default gateway without deleting the previously configured one overwrites the previous configuration.
When removing an IP interface, all of its default gateway IP addresses are removed.
An Alert message appears when attempting to insert a global IPv6 address.
An Alert message appears when attempting to insert more than one user-defined address.
To define an IPv6 Preferred Router:
1. Click System > IPv6 Default Gateway. The IPv6 Default Gateway Page opens.
Figure 11: IPv6 Default Gateway Page
The IPv6 Default Gateway Page contains the following fields:
The radio button is selected to delete/add/modify an entry.
Default Gateway IPv6 Address — Displays the Link Local IPv6 address of the default gateway.
Interface — Specifies the outgoing IPv6 interface through which the default gateway can be reached.
Typ e — Specifies the means by which the default gateway was configured. The possible field values are:
Static — Indicates the default gateway is user-defined.

Dynamic — Indicates the default gateway is dynamically configured.
State — Displays the default gateway status. The following states are available: Incomplete, Reachable,
Stale, Delay, Probe and Unreachable.
2. Select an Interface.
3. Click Add. The Add Static Default Gateway Page opens.
Figure 12: Add Static Default Gateway Page
4. Define the Default Gateway IPv6 Address field for the IP Interface. The address must be a valid IPv6 address, specified in hexadecimal using 16-bit values between colons. An example of an IPv6 address is 2031:0:130F:0:0:9C0:876A:130D and the compressed version is represented as 2031:0:130F::9C0:876A:130D.
5. Click Apply. The default gateway is defined, and the device is updated.
