show access-security slaac-snooping state



Display the SLAAC snooping state information to show interfaces that are blocked. SLAAC snooping extracts address information from Duplicate Address Detection (DAD) packets exchanged during the SLAAC process to build the SLAAC snooping table. The IPv6-MAC address bindings in this table are used to inspect and validate NDP/IP packets sent by IPv6 clients using SLAAC.

To restore an interface that has been blocked, you must issue the request access-security slaac-snooping unblock command.
