IPv6 Interface
– 1426 –
ipv6 nd ns-interval This command configures the interval between transmitting IPv6 neighbor
solicitation messages on an interface. Use the no form to restore the
default value.
SYNTAX
ipv6 nd ns-interval milliseconds
no ipv6 nd ns-interval
milliseconds - The interval between transmitting IPv6 neighbor
solicitation messages. (Range: 1000-3600000)
DEFAULT SETTING
1000 milliseconds is used for neighbor discovery operations
COMMAND MODE
Interface Configuration (VLAN)
COMMAND USAGE
â—† This command 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.
EXAMPLE
The following sets the interval between sending neighbor solicitation
messages to 30000 milliseconds:
Console(config)#interface vlan 1
Console(config)#pv6 nd ns-interval 30000
Console(config)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled
Link-local address:
FE80::200:E8FF:FE90:0/64
Global unicast address(es):
2009:DB9:2229::79, subnet is 2009:DB9:2229:0::/64
Joined group address(es):
FF01::1/16
FF02::1/16
FF02::1:FF00:79/104
FF02::1:FF90:0/104
IPv6 link MTU is 1500 bytes.
ND DAD is enabled, number of DAD attempts: 5.
ND retransmit interval is 1000 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
