Parameters
session-requests: Specifies the maximum number of PPPoE session requests from a user within the
monitoring time. The value range is 1 to 100000.
session-request-period: Specifies the monitoring time in the range of 1 to 3600 seconds.
blocking-period: Specifies the blocking time in the range of 1 to 3600 seconds.
Usage guidelines
This command limits the rate at which a user (identified by 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
time of monitoring entries is determined by the session-request-period argument. When the timer
expires, the system starts a new round of monitoring for the user.
• Blocking table—Stores a maximum of 8000 blocking entry. The system creates a blocking entry if
the access rate of a user reaches the threshold, and blocks requests from that user. When the
blocking entries reach the maximum, the system stops blocking session requests from new users and
it only outputs log messages. The aging time of the blocking entries is determined by the
blocking-period argument. When the timer expires, the system starts a new round of monitoring for
the user.
