Table 1: show services service-sets statistics ids session-limits counters Output Fields

Field Name

Field Description

TCP Counters

Session-limit TCP counters in the ingress direction for the following:

  • Sessions allowed—Number of TCP sessions allowed by the IDS rule.

  • Sessions ignored—Number of TCP sessions that did not undergo IDS processing because traffic matched a stateful firewall rule that included accept skip-ids.

  • Sessions dropped due to maximum reached—Number of TCP sessions dropped because the number of TCP sessions exceeded the limit.

  • Sessions dropped due to high rate—Number of TCP sessions dropped because the number of TCP connections per second exceeded the limit.

  • Packets allowed—Number of TCP packets that the IDS rule allowed.

  • Packets dropped due to high pps—Number of TCP packets dropped because the number of TCP packets per second exceeded the limit.

  • Sessions hit due to high rate—Number of TCP sessions affected because the number of TCP connections per second exceeded the limit.

    You can track TCP sessions on the IDS screen irrespective of the alarm-without-drop configuration.

UDP Counters

Session-limit UDP counters in the ingress direction for the following:

  • Sessions allowed—Number of UDP sessions allowed by the IDS rule.

  • Sessions ignored—Number of UDP sessions that did not undergo IDS processing because traffic matched a stateful firewall rule that included accept skip-ids.

  • Sessions dropped due to maximum reached—Number of UDP sessions dropped because the number of UDP sessions exceeded the limit.

  • Sessions dropped due to high rate—Number of UDP sessions dropped because the number of UDP connections per second exceeded the limit.

  • Packets allowed—Number of UDP packets that the IDS rule allowed.

  • Packets dropped due to high pps—Number of UDP packets dropped because the number of UDP packets per second exceeded the limit.

  • Sessions hit due to high rate—Number of UDP sessions affected because the number of UDP connections per second exceeded the limit.

    You can track UDP sessions on the IDS screen irrespective of the alarm-without-drop configuration.

ICMP Counters

Session-limit ICMP counters in the ingress direction for the following:

  • Sessions allowed—Number of ICMP sessions allowed by the IDS rule.

  • Sessions ignored—Number of ICMP sessions that did not undergo IDS processing because traffic matched a stateful firewall rule that included accept skip-ids.

  • Sessions dropped due to maximum reached—Number of ICMP sessions dropped because the number of ICMP sessions exceeded the limit.

  • Sessions dropped due to high rate—Number of ICMP sessions dropped because the number of ICMP connections per second exceeded the limit.

  • Packets allowed—Number of ICMP packets that the IDS rule allowed.

  • Packets dropped due to high pps—Number of ICMP packets dropped because the number of ICMP packets per second exceeded the limit.

  • Sessions hit due to high rate—Number of ICMP sessions affected because the number of ICMP connections per second exceeded the limit.

    You can track ICMP sessions on the IDS screen irrespective of the alarm-without-drop configuration.

Other-Protocols Counters

Session-limit counters in the ingress direction for protocols other than TCP, UDP, and ICMP for the following:

  • Sessions allowed—Number of sessions allowed by the IDS rule.

  • Sessions ignored—Number of sessions that did not undergo IDS processing because traffic matched a stateful firewall rule that included accept skip-ids.

  • Sessions dropped due to maximum reached—Number of sessions dropped because the number of sessions exceeded the limit.

  • Sessions dropped due to high rate—Number of sessions dropped because the number of connections per second exceeded the limit.

  • Packets allowed—Number of packets that the IDS rule allowed.

  • Packets dropped due to high pps—Number of packets dropped because the number of packets per second exceeded the limit.

  • Sessions hit due to high rate—Number of other protocol sessions affected because the number of other protocol connections per second exceeded the limit.
