The .../XXXXXXX.ipa/endpoint_id/monitor_rx file contains
|
||
|
|
the ID of the AP endpoint on which IPA "monitor" data is
|

|
|
received. The monitor endpoint supplies replicas of

packets that enter the IPA hardware for processing.
|
||
|
|
Each replicated packet is preceded by a fixed-size "ODL"
|
||
|
|
header (see .../XXXXXXX.ipa/feature/monitor, above).
|
||
|
|
Large packets are truncated, to reduce the bandwidth
|

|
|
required to provide the monitor function.
