Verifying Your Work

To verify that your configuration is correct, use the following commands on the monitoring station that is configured for passive flow monitoring:

To clear statistics for the show passive-monitoring error and show passive-monitoring flow commands, issue the clear passive-monitoring (all | interface-name) command.

You can also view passive flow monitoring status with the Simple Network Management Protocol (SNMP). The following Management Information Base (MIB) tables are supported:

The following section shows the output of the show commands used with the configuration example:


user@mon-station> show route 0/0 
 <skip inet.0>

# We are only concerned with the routing-instance route.

bc-vrf.inet.0:  1 destinations, 1 routes (1 active, 0 holddown, 0 hidden)
bc-vrf.inet.0:+ = Active Route, - = Last Active, * = Both
0.0.0.0/0          *[Static/5] 5d 17:34:57
                      via mo-4/0/0.1
                    > via mo-4/1/0.1
                      via mo-4/2/0.1
                      via mo-4/3/0.1
tcp-rt.inet.0: 13 destinations, 13 routes (12 active, 0 holddown, 1
hidden)

                    > via es-3/1/0.0
  : <other interface routes>
udp-rt.inet.0: 13 destinations, 13 routes (12 active, 0 holddown, 1
hidden)
+ = Active Route, - = Last Active, * = Both
0.0.0.0/0          *[Static/5] 19:24:39
                    > to 10.9.1.2 via fe-3/2/0.0
  : <other interface routes>

 

Note: For all show passive-monitoring commands, the output obtained when using a wildcard (such as *) or the all option is based on the configured interfaces listed at the [edit forwarding-options monitoring group-name] hierarchy level. In the output from the configuration example, you see information only for the configured interfaces mo-4/0/0, mo-4/1/0, mo-4/2/0, and mo-4/3/0.

Many of the statements you can configure in a monitoring group, such as engine-id and engine-type, are visible in the output of the show passive-monitoring commands.

Table 19: Output Fields for the show passive-monitoring error Command

Field

Explanation

Packets dropped (no memory)

Number of packets dropped because of memory.

Packets dropped (not IP)

Number of non-IP packets dropped.

Packets dropped (not IPv4)

Number of packets dropped because they failed the IPv4 check.

Packets dropped (header too small)

Number of packets dropped because the packet length or IP header length was too small.

Memory allocation failures

Number of flow record memory allocation failures. A small number reflects failures to replenish the free list. A large number indicates the monitoring station is almost out of memory space.

Memory free failures

Number of flow record memory frees.

Memory free list failures

Number of flow records received from free list that failed. Memory is nearly exhausted or too many new flows greater than 128K are being created in one second.

Memory warning

The flows have exceeded 1 million packets per second (Mpps) on a Monitoring Services PIC or 2 Mpps on a Monitoring Services II PIC. The response can be Yes or No.

Memory overload

The memory has been overloaded. The response is Yes or No.

PPS overload

In packets per second, whether the PIC is receiving more traffic than the configured threshold. The response can be Yes or No.

BPS overload

In bytes per second, whether the PIC is receiving more traffic than the configured threshold. The response can be Yes or No.
