MPW-1 MP-4100 Ver. 2.0 Monitoring Performance 4-11
Parameter Description
Connectivity Status Displays the connectivity status of the selected pseudowire:
OK – the pseudowire carries traffic, and both the remote and the local pseudowire
endpoints receive Ethernet frames. However, there may be problems such as
sequence errors, underflows, overflows, etc., which may be displayed using the
Statistics function.
LOCAL FAIL – a failure has been detected at the local pseudowire endpoint.
REMOTE FAIL – a failure is reported by the remote pseudowire endpoint.
UNAVAILABLE – the pseudowire reports loss of connectivity (it did not receive
neither OAM, nor data packets for 10 seconds or more (OAM link then reports loss
of synchronization). This is often caused by network problems, or configuration
errors.
VALIDATION FAIL – the remote pseudowire endpoint replied to OAM packets, but
there is a configuration mismatch (the configuration parameters used at two
endpoints of the pseudowire are different).
TX Packets Total number of frames transmitted toward the PSN
RX Packets Total number of frames received from the PSN
Sequence Errors Total number of packets that did not arrive in time, as expected according to their
sequence number (either because they were lost in the network, or reordered). See

Jitter Buffer
Underflows
Total number of jitter buffer underflow events. See also

Jitter Buffer
Overflows
Total number of jitter buffer overflow events. See also

Monitoring Internal DS1 Port Status
When an internal DS1 port of the MPW-1 is included in a redundancy pair, the
current redundancy status can be displayed.
³ To display the Int DS1 status:
1. Select Monitoring > Physical > I/O > I/O 2 (MPW1) > Int-DS1 > Status.
2. The screen displays the current function of the selected port within the Int
DS1 pair:
Active The port is the active port (the port carrying the traffic).
Standby The port is in standby, and does not carry traffic.
Monitoring the Timing Source Status
Megaplex-4100 monitoring function enables displaying information regarding the
current MPW-1 timing source (see details in the
Megaplex-4100 Installation and
Operation Manual
).
