Parameters
aging-time: Specifies the aging timer for ND entries in stale state, in the range of 1 to 1440 minutes.
Usage guidelines
This aging time applies to all ND entries in stale state. If an ND entry in stale state is not updated
before the timer expires, it moves to the delay state. If it is still not updated in 5 seconds, the ND entry
moves to the probe state. 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 aging timer for ND entries in stale state to 120 minutes.

[Sysname] ipv6 neighbor stale-aging 120
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 max-number
undo ipv6 neighbors max-learning-num
Default
The maximum number of dynamic neighbor entries that an interface can learn equals the ND table
capacity of the device. You can use the switch-mode command to set the ND table capacity. For
information about the switch-mode command, see Fundamentals Configuration Guide.

Parameters
max-number: Specifies the maximum number of dynamic neighbor entries that an interface can
learn. The minimum value is 1. The maximum value equals the ND table capacity of the device.
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.
