Release Information

Command introduced before JUNOS Release 7.4.

Description

(M40e, M160, and M320 routers and T Series routers only) Display passive monitoring error statistics.

Options

* | all | mo-fpc/pic/port — Display error statistics for monitoring interfaces. Use a wildcard character, specify all interfaces, or provide a specific interface name.

Output Fields

Table 210 lists the output fields for the show passive-monitoring error command. Output fields are listed in the approximate order in which they appear.

Table 210: show passive-monitoring error Output Fields

Field Name	Field Description
Passive monitoring interface	Name of the passive monitoring interface.
Local interface index	Index counter of the local interface.
Interface state	State of the passive monitoring interface: Monitoring—Specified interface is actively monitoring. Disabled—Specified interface has been disabled from the CLI. Not monitoring—The interface is operational, but not monitoring. This condition occurs when an interface first comes online, or when the interface is operational, but no logical unit has been configured under the physical interface. Unknown—Unknown state. Error—An error occurred during the process of determining the state of the interface.
Error information
Packets dropped (no memory)	Number of packets dropped because of memory shortage.
Packets dropped (not IP)	Number of non-IP packets dropped.
Packets dropped (not IPv4)	Number of packets dropped because they failed the IPv4 version 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 free failures.
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 128 KB are being created per second.
Memory warning	Whether 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	Whether the memory has been overloaded. The response can be Yes or No.
PPS overload	Whether the PIC is receiving more packets per second than the configured threshold. The response can be Yes or No.
BPS overload	Whether the PIC is receiving more bits per second than the configured threshold. The response can be Yes or No.
