The value is a 32-digit hexadecimal number in X:X:X:X:X:X:X:X format. |

Usage Scenario
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. Run the reset nd snooping prefix command to delete prefix management entries of users if the following requirements are met:
Precautions
After a prefix management entry is deleted, the switch cannot establish the ND snooping dynamic binding table for new users with the prefix management entry.
