Metrics (PON)
Access to PON Metrics is located on the PON Port Menu Bar.
Metrics comprises four viewing screens.
- Counters (Traffic Analysis)
- Status
- T-CONT Metrics
- Guaranteed Bandwidth Allocation
Counters (Traffic Analysis)
Traffic Analysis displays the following attributes:
- Bytes - The Type (Counter) and number of bytes received (rec) or transmitted (Tx).
- Frames - The Type (Counter) and number of frames received (rec) or transmitted (Tx).
- BIP8 Error - The Type (Counter) and number of frames received (rec) with bit interleaved parity 8 (BIP8) errors.
- Utilization (bps) - The Type (Rate) in of bps of utilization received (rec) or transmitted (Tx).
- Utilization (%) - The Type (Rate) in of percentage of utilization received (rec) or transmitted (Tx).
- Unicast Packets - The Type (Rate) and number of unicast packets received (rec) or transmitted (Tx).
- Unicast Bytes - The Type (Rate) and number of unicast bytes received (rec) or transmitted (Tx).
- Broadcast Packets - The Type (Rate) and number of broadcast packets received (rec) or transmitted (Tx).
- Broadcast Bytes - The Type (Rate) and number of broadcast bytes received (rec) or transmitted (Tx).
- Multicast Packets - The Type (Rate) and number of multicast packets received (rec) or transmitted (Tx).
- Multicast Bytes - The Type (Rate) and number of multicast bytes received (rec) or transmitted (Tx).
- Flooded Packets - The Type (Rate) number of flooded packets transmitted (Tx).
- Flooded Bytes -The Type (Rate) number of flooded bytes transmitted (Tx).

STATUS
PON Status displays the following attributes:
- Operational Status - The port operational status (for example, Down).
- Availability State - Indicates the optical connection data availability status (for example, Normal).
- Transmit Line Rate (Kbps) - The transmit line rate on this port, in kilobits per second (Kbps).
- Receive Line Rate (Kbps) - The receive line rate on this port, in kilobits per second (Kbps).
- Receive Aggerate Rate (Kbps) - The receive aggregate percentage on this port, as a percentage (%).
- Receive Aggerate Percentage (%)-
TCONT Metrics
The T-CONT comprises the Transmission Container (T-CONT) and the ONT Identifier (ONT-ID) of each ONT activated on the PON. Traffic classes are listed by priority, 0 through 7, with ONT Management and Control Interface (OMCI), having the highest priority (0). The bandwidth allocated for OMCI applies to all ONTs on this PON, not on a connection basis. The bandwidth allocated for priorities 1 through 7 is on a connection basis.
Transmission Container (T-CONT) metrics display the following attributes:
- Attributes - The Class of Service (CoS) settings map to a different CoS traffic contract (T-CONT) that includes:
- OMCI - Management and Control Interface (OMCI), has the highest priority (0). The bandwidth allocated for OMCI applies to all ONTs on this PON, not on a connection basis. The bandwidth allocated for priorities 1 through 7 is on a connection basis.
- CBR2 - Used for connections that transport traffic where the sustained and peak rates are identical. Typical applications include voice services that require a constant allocation of bandwidth for signaling. The bandwidth is allocated, whether used or not.
- CBR1 - Used for connections that transport traffic at variable rates. A typical application that uses CBR1 is compressed video streams. Use when latency is of the utmost concern. The bandwidth is allocated, whether used or not.
- VBR - Used for connections that transmit bit-rate traffic for which there is no inherent reliance on time synchronization between the traffic source and destination, but there is a need for an attempt at a specified bandwidth. An application that might require nrt-VBR service is Voice over Internet Protocol (VoIP) or IP-based VTC applications. This is an enhanced class of service with a higher priority than UBR connections.
- UBR - Unspecified bit rate (default). Used for connections that transport variable bit rate traffic for which there is no reliance on time synchronization between the source and destination. UBR is generally used for applications that are very tolerant of delay and cell loss, such as file transfers, e-mail, IP streams, and general LAN connections, etc. Typical Active Ethernet CoS.
Default is UBR.
- Total Maximum BW (Kbps) - Total maximum upstream bandwidth available for all connections utilizing the configured Connections Profile.
- Total Assured BW (Kbps) - Total assured upstream bandwidth allocated for all connections utilizing the configured Connections Profiles.
