Backing Up DHCP Snooping Binding Entries

Backing Up DHCP Snooping Binding Entries


If binding entries are not backed up, the binding entries will be lost after the device restarts. DHCP users must log in again so that the device can generate DHCP snooping binding entries for DHCP users to communicate. After DHCP snooping binding entries are backed up, DHCP snooping binding entries can be restored after the device restarts.


  1. Run system-view

    The system view is displayed.

  2. Run dhcp snooping user-bind autosave file-name [ write-delay delay-time ]

    The device is enabled to back up dynamic DHCP snooping binding entries.

    By default, local automatic backup of the DHCP snooping binding table is disabled.
