The show session limit parameter command displays the following information.
Output field | Description |
---|---|
Sessions allowed | Total number of sessions allowed. |
Sessions blocked | Total number of sessions blocked (sum of rate-limit sessions blocked and max-halfopen sessions blocked) |
Current session counts | Number of current established, half-open, and terminating sessions that matched rules assigned to this session. |
Max session counts | Maximum values of session counts since the last counter reset. |
Time since last session created | Time since the last session was created. |
Sessions per second average | Session per-second rates averaged over the last one second, one minute, and five minutes. |
Max sessions per second | Highest value of sessions per-second rates since the last counter reset. |
Time since max sessions per sec | Time since the Max sessions per second value occurred. |
Time since last session blocked | Time since the last session was blocked. |
Max sessions blocked per sec avg | Highest values of Sessions per second average. |
Features | Features enabled on the session policy (rate-limit, max-halfopen). |
Rate sessions/second | Rate-limit feature maximum sessions per second since configuration time. |
Max burst | Rate-limit feature maximum burst of sessions created since configuration time. |
Interval (milliseconds) | Rate-limit interval derived from the configured rate and burst values. |
Sessions blocked | Sessions blocked due to the rate-limit rate being exceeded. |
Max halfopen maximum | Max-halfopen sessions limit. After the number of halfopen sessions reaches this value, no further sessions are created. |
Sessions blocked | Sessions blocked due to the max-halfopen value being exceeded. |
The following example shows how to display detailed session limit parameter information.
