Synchronizing the Binding Table
To synchronize the contents of the dhcpBinding.db file with the binding table contents that resides in
memory, use the ip helper dhcp-snooping binding action command. This command provides two param-
eters: purge and renew. Use the purge parameter to clear binding table entries in memory and the renew
parameter to populate the binding table with the contents of the dhcpBinding.db file. For example:
-> ip helper dhcp-snooping binding action purge
-> ip helper dhcp-snooping binding action renew
Synchronizing the binding table is only done when this command is used. There is no automatic trigger-
ing of this function. In addition, it is important to note that synchronizing the binding table loads dhcp-
Binding.db file contents into memory. This is the reverse of saving the binding table contents in memory
to the dhcpBinding.db file, which is done at automatic time intervals as defined by the binding table time-
out value. See “Configuring the Binding Table Timeout” on page 18-21 for more information.
