Field
Description
VLAN A VLAN is marked “up” if the switch can send and receive packets on this
interface, “down” if a line signal is not present, or “administratively down”
if the interface has been disabled by the administrator.
IPv6
IPv6 is marked “enable” if the switch can send and receive IP traffic on this
interface, “disable” if the switch cannot send and receive IP traffic on this
interface, or “stalled” if a duplicate link-local address is detected on the
interface.
Link-local
address
Shows the link-local address assigned to this interface
Global unicast
address(es)
Shows the global unicast address(es) assigned to this interface
Joined group
address(es)
In addition to the unicast addresses assigned to an interface, a node is
required to join the all-nodes multicast addresses FF01::1 and FF02::1 for
all IPv6 nodes within scope 1 (interface-local) and scope 2 (link-local),
respectively.
FF01::1/16 is the transient node-local multicast address for all attached
IPv6 nodes, and FF02::1/16 is the link-local multicast address for all
attached IPv6 nodes. The node-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.
MTU
Maximum transmission unit for this interface.
ND DAD
Indicates whether (neighbor discovery) duplicate address detection is
enabled.
number of DAD
attempts
The number of consecutive neighbor solicitation messages sent on the
interface during duplicate address detection.
ND retransmit
interval
The interval between IPv6 neighbor solicitation retransmissions sent on an
interface during duplicate address detection.
This example displays a brief summary of IPv6 addresses configured on the
switch.
