ADDRMAPCFG
Describes and configures the probe support for the network layer and application layer host tables for this protocol. The value can be one of the following:

  • NOT SUPPORTED

  • SUPPORTED OFF

  • SUPPORTED ON

If the value is SUPPORTED ON, the probe adds entries to the address map table that maps the network layer address to the MAC layer address.

HOSTCFG

Describes and configures the probe support for the network layer and application layer host tables for this protocol. The value can be one of the following:

  • NOT SUPPORTED

  • SUPPORTED OFF

  • SUPPORTED ON

If the value is SUPPORTED ON, the probe adds entries to the Host Control table to collect statistics for network layer and application layer hosts.

MATRIXCFG

Describes and configures the probe support for the network layer and application layer host tables for this protocol. The value can be one of the following:

  • NOT SUPPORTED

  • SUPPORTED OFF

  • SUPPORTED ON

OWNER

Shows the entity that configured this entry.

DATASOURCE

Shows the source of data for the entry.

DROPFRAMES

Shows the total number of frames that the probe receives and drops. This value does not include packets that were not counted because they had MAC-layer errors.

CREATETIME

Shows when the entry was last activated.

NHDROPFRAMES

Shows the total number of network host frames that the probe receives and drops. This value does not include packets that were not counted because they had MAC-layer errors.

AHDROPFRAMES

Shows the total number of application layer host frames that the probe receives and drops. This value does not include packets that were not counted because they had MAC-layer errors.
