Syntax

content_copy zoom_out_map
show access-security slaac-snooping statistics
<interface (interface-name | all>

Description

Display the statistics for IPv6 clients using stateless address auto-configuration (SLAAC). 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.

Options

interface (interface-name | all)

Display the SLAAC snooping statistics for the specified interface or for all interfaces.

logical-system logical-system-name

Display the SLAAC snooping statistics for the specified logical system.

routing-instance routing-instance-name

Display the SLAAC snooping statistics for the specified routing instance.
