4-2 Monitoring Performance MPW-1 MP-4100 Ver. 2.0
• For pseudowires terminated on MPW-1 ports:
Status data for each pseudowire
Pseudowire transmission statistics
The MPW-1 pseudowire performance monitoring functions are accessed after
selecting the desired pseudowire under Monitoring > Applications > Multi-
Service over PSN > PW.
• When protection is used for MPW-1 ports, and/or for pseudowire connections
terminated on MPW-1 ports: protection status. The protection status is
accessed using Monitoring > Physical > I/O > Int DS1 > Status.
• When pseudowires are used as system timing sources: display the status of
the (adaptive) clock recovery mechanism. The recovered clock status is
accessed using Monitoring > System > Timing.
The collected data enables the system administrator to monitor the transmission
performance, and thus the quality of service provided to users, for statistical
purposes. In addition, when problems are reported by users served by MPW-1,
the collected data can be used for diagnostic purposes, because it can help
identify the source of the problem.
The performance statistics data is continuously collected, and is stored as long as
the equipment operates. The stored data is deleted when the MPW-1 is reset or
removed, and is also lost when the Megaplex-4100 is powered down.
Monitoring Ethernet Ports
The Ethernet port physical layer performance monitoring data includes:
• Status data for the port.
• Statistics data. Statistics can be displayed only for enabled ports: if the
Ethernet port is not enabled, its monitoring display is empty.
³ To display status data for an Ethernet port:
1. Navigate to the Monitoring > Physical Layer > I/O > Ethernet screen of the
desired module, and select the desired Ethernet port, ETH 1, ETH 2, or ETH 3.
2. On the Ethernet port screen, select Status. The Ethernet port status
parameters are explained in
Table
4-1
.
3. For an Ethernet port with optical interface, you can also display information
and status data for the SFP serving the port: select SFP Status on the
corresponding Ethernet port Status screen. The SFP status parameters are
explained in
Table
4-2
.
When no SFP is installed, or the data cannot be read, you will see Unknown for
the Connector Type, and the other fields display zero.
