Table 1: 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.
