| IP Configuration
Setting the Switch’s IP Address (IP Version 6)
Discovery to discover each other's presence, to determine each other's link-
layer addresses, to find routers and to maintain reachability information about
the paths to active neighbors. The key parameters used to facilitate this process
are the number of attempts made to verify whether or not a duplicate address
exists on the same network segment, and the interval between neighbor
solicitations used to verify reachability information.
Parameters
These parameters are displayed:
◆
VLAN – ID of a configured VLAN which is to be used for management access, or
as a standard interface for a subnet. 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 Autoconfig – Enables stateless autoconfiguration of an IPv6 address
on an interface and enables IPv6 functionality on that interface. The network
portion of the address is based on prefixes received in IPv6 router
advertisement messages, and the host portion is automatically generated
using the modified EUI-64 form of the interface identifier (i.e., the
switch’s MAC
address).
■
If a link local address has not yet been assigned to this interface, this
command will dynamically generate one. The link-local address is made
with an address prefix in the range of FE80~FEBF and a host portion based
the
switch’s MAC address in modified EUI-64 format. It will also generate a
global unicast address if a global prefix is included in received router
advertisements.
■
When DHCPv6 is started, the switch may attempt to acquire an IP address
prefix through stateful address autoconfiguration. If router advertisements
have the
“other stateful configuration” flag set, the switch will attempt to
acquire other non-address configuration information (such as a default
gateway).
■
If auto-configuration is not selected, then an address must be manually
configured using the Add IPv6 Address page described below.
◆
Enable IPv6 Explicitly – Enables IPv6 on an interface and assigns it a link-local
address. Note that when an explicit address is assigned to an interface, IPv6 is
automatically enabled, and cannot be disabled until all assigned addresses
have been removed. (Default: Disabled)
Disabling this parameter does not disable IPv6 for an interface that has been
explicitly configured with an IPv6 address.
◆ MTU – Sets the size of the maximum transmission unit (MTU) for IPv6 packets
sent on an interface. (Range: 1280-65535 bytes; Default: 1500 bytes)
■
The maximum value set in this field cannot exceed the MTU of the physical
interface, which is currently fixed at 1500 bytes.
