Setting the Switch’s IP Address (IP Version 6)
– 670 –
■
Configuring a value of 0 disables duplicate address detection.
■
Duplicate address detection determines if a new unicast IPv6 address
already exists on the network before it is assigned to an interface.
■
Duplicate address detection is stopped on any interface that has been
suspended (see “Configuring VLAN Groups” on page 171). While an
interface is suspended, all unicast IPv6 addresses assigned to that interface
are placed in a “pending” state. Duplicate address detection is
automatically restarted when the interface is administratively re-activated.
■
An interface that is re-activated restarts duplicate address detection for all
unicast IPv6 addresses on the interface. While duplicate address detection
is performed on the interface’s link-local address, the other IPv6 addresses
remain in a “tentative” state. If no duplicate link-local address is found,
duplicate address detection is started for the remaining IPv6 addresses.
■
If a duplicate address is detected, it is set to “duplicate” state, and a warning
message is sent to the console. If a duplicate link-local address is detected,
IPv6 processes are disabled on the interface. If a duplicate global unicast
address is detected, it is not used. All configuration commands associated
with a duplicate address remain configured while the address is in
“duplicate” state.
■
If the link-local address for an interface is changed, duplicate address
detection is performed on the new link-local address, but not for any of the
IPv6 global unicast addresses already associated with the interface.
◆ ND NS Interval – The interval between transmitting IPv6 neighbor solicitation
messages on an interface. (Range: 1000-3600000 milliseconds)
Default: 1000 milliseconds is used for neighbor discovery operations,
0 milliseconds is advertised in router advertisements.
This attribute specifies the interval between transmitting neighbor solicitation
messages when resolving an address, or when probing the reachability of a
neighbor. Therefore, avoid using very short intervals for normal IPv6
operations.
When a non-default value is configured, the specified interval is used both for
router advertisements and by the router itself.
◆ ND Reachable-Time – The amount of time that a remote IPv6 node is
considered reachable after some reachability confirmation event has occurred.
(Range: 0-3600000 milliseconds)
Default: 30000 milliseconds is used for neighbor discovery operations,
0 milliseconds is advertised in router advertisements.
■
The time limit configured by this parameter allows the router to detect
unavailable neighbors. During the neighbor discover process, an IPv6 node
will multicast neighbor solicitation messages to search for neighbor nodes.
For a neighbor node to be considered reachable, it must respond to the
neighbor soliciting node with a neighbor advertisement message to
become a confirmed neighbor, after which the reachable timer will be
considered in effect for subsequent unicast IPv6 layer communications.
