IPv6 Interface
ipv6 nd reachable-time
This command configures the amount of time that a remote IPv6 node is considered reachable
after some reachability confirmation event has occurred.
Syntax
ipv6 nd reachable-time milliseconds
no ipv6 nd reachable-time
milliseconds - The time that a node can be considered reachable after receiving
confirmation of reachability.
(Range: 0-3600000)
Default Setting
30000 milliseconds is used for neighbor discovery operations
Command Mode
Interface Configuration (VLAN)
Command Usage
The time limit configured by this command allows the switch to detect unavailable neighbors.
Example
The following sets the reachable time for a remote node to 1000 milliseconds:
Console(config)#interface vlan 1
Console(config)#pv6 nd reachable-time 1000
Console(config)#
clear ipv6 neighbors
This command deletes all dynamic entries in the IPv6 neighbor discovery cache.
Command Mode
Privileged Exec
Example
The following deletes all dynamic entries in the IPv6 neighbor cache:
Console#clear ipv6 neighbors
Console#
show ipv6 neighbors
This command displays information in the IPv6 neighbor discovery cache.
Syntax
show ipv6 neighbors [vlan vlan-id | ipv6-address]
vlan-id - VLAN ID (Range: 1-4093)
ipv6-address - The IPv6 address of a neighbor device. You can specify either a link-local or
global unicast address formatted according to RFC 2373 “IPv6 Addressing Architecture,”
