Usage guidelines
After logging for IPsec packets is enabled, the device outputs a log when an IPsec packet is discarded
due to, for example, lack of inbound SA, AH/ESP authentication failure, or ESP encryption failure. A log
contains the source and destination IP addresses, SPI, and sequence number of the packet, and the
reason it was discarded.

# Enable logging for IPsec packets.
<Sysname> system-view
[Sysname] ipsec logging packet enable
