Parameters
aging-time: Specifies the age timer for ND entries in stale state, in the range of 1 to 1440 minutes.
Usage guidelines
ND entries in stale state have an age timer. If an ND entry in stale state is not refreshed before the
timer expires, it moves to the delay state. If it is still not refreshed in 5 seconds, the ND entry moves
to the probe state, and the device sends an NS message for detection a maximum of three times. If
no response is received, the device deletes the ND entry.
Examples
# Set the age timer for ND entries in stale state to 120 minutes.

ipv6 neighbors max-learning-num
Use ipv6 neighbors max-learning-num to set the maximum number of dynamic neighbor entries
that an interface can learn. This prevents the interface from occupying too many neighbor table
resources.
Use undo ipv6 neighbors max-learning-num to restore the default.
Syntax
ipv6 neighbors max-learning-num number
undo ipv6 neighbors max-learning-num
Default
An interface can learn a maximum of 8192 dynamic neighbor entries.

Parameters
number: Specifies the maximum number of dynamic neighbor entries that an interface can learn.
The value range is 1 to 8192.
Usage guidelines
The device can dynamically acquire the link-layer address of a neighboring node through NS and NA
messages and add it into the neighbor table.
When the number of dynamic neighbor entries reaches the threshold, the interface stops learning
neighbor information.
Examples
# Set the maximum number of dynamic neighbor entries that VLAN-interface 100 can learn to 10.

[Sysname] interface vlan-interface 100
