reported independently by the performance monitoring process. Each
set of parameters forms a threshold group.
The parameters specified in each threshold group are summarized as
follows:
• flag to inhibit day threshold-crossing alert
• day threshold for each type of packet layer count
• flag to inhibit 15-minute threshold-crossing alert
• 15-minute threshold for each type of packet-error count
MML Commands
The following MML commands are used to control and retrieve SIP
performance measurements:
• INIT:FAC
• OP:FAC
• ALW:FAC
• INH:FAC
Ethernet Layer
Performance Monitoring
Parameters
Overview
The following parameters are used to monitor Ethernet layer
performance:
• Incoming Ethernet Frames Discarded
• Outgoing Ethernet Frames Discarded
• Invalid Ethernet Header
• MAC Sublayer Error
• Ethernet Unavailable Seconds
Incoming Ethernet Frames Discarded
This count keeps track of the total number of incoming Ethernet
frames discarded due to the following error types:
• Unknown protocol
• Unsupported protocol
• Exceeds maximum permitted frame size
• Invalid frame check sequence
