Setting the Session Thresholds for System-Level Traffic Statistics and Monitoring

Setting the Session Thresholds for System-Level Traffic Statistics and Monitoring

Context

System-level traffic statistics and monitoring take effect on all the data flows in interzones that are enabled with the firewall feature. That is, the Router collects statistics about the ICMP, TCP, and UDP sessions in the interzones. When the number of sessions exceeds the threshold, the Router restricts the sessions until the number of sessions is less than the threshold.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    firewall statistics system enable

    The system-level traffic statistics and monitoring are enabled.

    By default, the system-level traffic statistics and monitoring is disabled.

  3. (Optional) Run:

    firewall statistics system connect-number { frag | icmp | tcp | tcp-proxy | udp } high high-threshold low low-threshold

    The session thresholds for the system-level traffic statistics and monitoring are set.

    For the system-level traffic statistics, you can set the thresholds for each type of session. For example, you can set the upper threshold for TCP sessions to 15000 and lower threshold to 12000. When the number of TCP sessions in all interzones exceeds 15000, the Router denies all new TCP sessions in the interzone and reports an alarm to the information center. If the number of TCP sessions falls below 12000, the Router generates a recovery log and sends the log to the information center.

    The default upper threshold is 16384, and the default lower threshold is 12288.
