The IPv6 RA guard log function records RA message processing information to meet the audit requirements of administrators. After this function is enabled, the device generates the ND_RAGUARD/3/ND_RAGUARD_DROP log when detecting invalid RA messages. The log content includes the name of the attacked interface, source IP address and source MAC address of RA messages, and total number of RA messages discarded on the interface.
The IPv6 RA guard logs generated by the device are sent to the information center module for processing. The configuration of the information center module determines the output rules and output directions of the logs. For details about the information center, see Information Center Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Device Management.
