(Optional) Setting the Maximum Number of ND Snooping Dynamic Binding Entries to Be Learned by an Interface

Context

If a lot of users go online through an interface, the device consumes many ND snooping dynamic binding entries to process the NS packets. To prevent this problem, you can set the maximum number of ND snooping dynamic binding entries to be learned by an interface. When the number of the ND snooping dynamic binding entries learned by an interface reaches the maximum number, no entry can be added.

You can set the maximum number of ND snooping entries in the system view or interface view. The configuration in the system view is valid for all interfaces. The settings in the interface view only take effect on the specified interface. If the settings are performed in both the interface view and system view, the smaller value is adopted.

Procedure

In the system view
1. Run system-view
  The system view is displayed.
2. Run nd snooping max-user-number max-user-number
  Maximum number of ND snooping dynamic binding entries to be learned by an interface is set.
  
  By default, the maximum number of ND snooping dynamic binding entries to be learned by an interface is the same as the number of ND snooping entries supported by the device.
In the interface view
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The interface view is displayed.
3. Run nd snooping max-user-number max-user-number
  Maximum number of ND snooping dynamic binding entries to be learned by an interface is set.
  
  By default, the maximum number of ND snooping dynamic binding entries to be learned by an interface is the same as the number of ND snooping entries supported by the device.
