Table 1: show services stateful-firewall flow-analysis Output Fields

Field Name

Field Description

Total Flows Active

Total active flows in the MS-PIC including TCP, UDP, ICMP and Softwires.

Total TCP Flows Active

Total active TCP flows in the MS-PIC.

Total UDP Flows Active

Total active UDP flows in the MS-PIC.

Total Other Flows Active

Total other active flows in the MS-PIC including ICMP and softwires.

Total Predicted Flows Active

Predicted flows are created only by the ALG traffic using the L3/L4 information available.

Created Flows per Second

Flow setup rate at the time of running the command.

Deleted Flows per Second

Flow deletion rate at the time of running the command.

Peak Total Flows Active

The highest number of active flows since the last PIC restart or since the last time flow statistics are flushed.

Peak Total TCP Flows Active

The highest number of active TCP flows since the last PIC restart or since the last time flow stats are flushed.

Peak Total UDP Flows Active

The highest number of active UDP flows since the last PIC restart or since the last time flow statistics are flushed.

Peak Total Other Flows Active

The highest number of other active flows since the last PIC restart or since the last time flow statistics are flushed.

Peak Created Flows per Second

The maximum flow setup rate observed since the last PIC restart or since the last time flow statistics are flushed.

Peak Deleted Flows per Second

The maximum flow deletion rate observed since the last PIC restart or from the last time flow statistics are flushed.

Average HTTP Flow Lifetime(ms)

Average HTTP Flow Lifetime in millisecond.

Packets received

The total number of packets received by the MS-PIC.

Packets transmitted

The total number of packets transmitted by the MS-PIC.

Slow path forward

The number of packets forwarded in the slow path (i.e. after the successful rule match and flow creation).

Slow path discard

The number of packets discarded before the flow creation.

Flow Rate Data: Number of Samples

The number of samples used to calculate the flow rate, since the last PIC restart or since the last time flow statistics are flushed.

Flow Rate Distribution(sec) Flow Operation :Creation Flow Operation :Deletion

Histogram of the samples used for flow rate calculation.

Flow Lifetime Distribution(sec):

Histogram of the samples used to calculate the flow life time in sec.
