Chapter 46 Configuring IPv6 for Gigabit Ethernet Interfaces
Configuring Neighbor Discovery Parameters
Reachability Time
To configure the reachability time, follow these steps:
Retransmission Time
To configure the retransmission time, follow these steps:
Verifying Neighbor Discovery Parameter Configuration
The
show ipv6 interface
command displays the configuration of the neighbor discovery parameters.
switch#
show ipv6 interface mgmt 0
mgmt0 is up
IPv6 is enabled
Global address(es):
2003::1/64
Link-local address(es):
fe80::205:30ff:fe00:533e
ND DAD is enabled, number of DAD attempts: 5
Step 3
switch(config-if)#
ipv6 nd dad attempts 3
Sets the duplicate address detection attempts
count to 100. The range is 0 to 15.
Step 4
switch(config-if)#
no ipv6 nd dad attempts
Reverts to the default value (0).
Note
When the attempt count is set to 0,
neighbor discovery is disabled.

switch(config)#
Enters configuration mode.
Step 2
switch(config)#
interface gigabitethernet 3/1
switch(config-if)#
Specifies an interface and enters interface
configuration submode.
Step 3
switch(config-if)#
ipv6 nd reachability-time
10000
Sets the reachability time to 10000 milliseconds.
The range is 1000 to 3600000 milliseconds.
Step 4
switch(config-if)#
no ipv6 nd
reachability-time
Reverts to the default value (30000
milliseconds).
