Showing IPv6
Addresses
Use the System > IPv6 Configuration (Show IPv6 Address) page to display the IPv6
addresses assigned to an interface.
Parameters
These parameters are displayed:
◆
VLAN – ID of a configured VLAN. 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)
◆
IPv6 Address Type – The address type (Global, EUI-64, Link Local).
◆
IPv6 Address – An IPv6 address assigned to this interface.
In addition to the unicast addresses assigned to an interface, a node is also
required to listen to the all-nodes multicast addresses FF01::1 (interface-local
scope) and FF02::1 (link-local scope).
FF01::1/16 is the transient interface-local multicast address for all attached IPv6
nodes, and FF02::1/16 is the link-local multicast address for all attached IPv6
nodes. The interface-local multicast address is only used for loopback
transmission of multicast traffic. Link-local multicast addresses cover the same
types as used by link-local unicast addresses, including all nodes (FF02::1), all
routers (FF02::2), and solicited nodes (FF02::1:FFXX:XXXX) as described below.
A node is also required to compute and join the associated solicited-node
multicast addresses for every unicast and anycast address it is assigned. IPv6
addresses that differ only in the high-order bits, e.g. due to multiple high-order
prefixes associated with different aggregations, will map to the same solicited-
node address, thereby reducing the number of multicast addresses a node
must join. In this example, FF02::1:FF90:0/104 is the solicited-node multicast
address which is formed by taking the low-order 24 bits of the address and
appending those bits to the prefix.
Note that the solicited-node multicast address (link-local scope FF02) is used to
resolve the MAC addresses for neighbor nodes since IPv6 does not support the
broadcast method used by the Address Resolution Protocol in IPv4.
These additional addresses are displayed by the "show ip interface" command
described in the CLI Reference Guide).
◆
Configuration Mode – Indicates if this address was automatically generated or
manually configured.
