Limiting the PPPoE access rate

The device can limit the rate at which a user (identified by an MAC address) can create PPPoE sessions
on an interface. If the number of PPPoE requests within the monitoring time exceeds the configured
threshold, the device discards the excessive requests, and outputs log messages. If the blocking time is set
to 0, the device does not block any requests, and it only outputs log messages.
The device uses a monitoring table and a blocking table to control PPP access rates:
Monitoring table—Stores a maximum of 8000 monitoring entries. Each entry records the number of
•
PPPoE sessions created by a user within the monitoring time. When the monitoring entries reach the
maximum, the system stops monitoring and blocking session requests from new users. The aging
