dhcpv6-snooping external-storage

Description

配置外部存储用于支持up IPv6 bindings (used by DHCPv6 snooping) to a file. When configured, the switch stores all the IP bindings in an external storage file so that they are retained after the switch restarts. When the switch restarts, it reads the IPv6 bindings from the configured external storage file to populate its local cache.

The no form of this command disables the saving of IPv6 bindings in an external storage file.
