Configure Storing of DHCPv6 snooping Bound Entries
The DHCPv6 snooping function supports the auto or manual storing to the device FLASH. If the device restarts, the stored bound entries can be restored, avoiding affecting the communication because the bound entries are lost.
Configuration Condition
Before configuring the storing of the DHCPv6 snooping bound entries, first complete the following task:
- Enable the DHCPv6 snooping function
Configure the Storing of DHCPv6 snooping Bound Entries
The system periodically refreshes the DHCPv6 snooping bound entries, detecting whether the bound entries are updated. If yes, we need to store the updated entries to the specified path after the storing delay arrives. Meanwhile, you also can store the bound entries to the device FLASH immediately.
