Clearing the Prefix Management Table

The ND server that functions as the gateway router sends RA packets periodically to instruct users to update prefixes. The switch that functions as the access device establishes prefix management entries based on RA packets to maintain and manage user prefixes.

Generally, do not delete prefix management entries of users manually. You need to manually delete prefix management entries if the following requirements are met:

• The user lease does not expire and the prefix management table cannot age automatically.
• The user is no longer connected to the network.

To manually delete prefix management entries, run the following command in the user view.
