MPW-1 MP-4100 Ver. 2.0 Monitoring Performance 4-7
Parameter Description
PW Type Displays the pseudowire type (protocol):
TDMoIP CE – Pseudowire using TDMoPSN circuit emulation.
HDLC – Pseudowire using the HDLCoPSN protocol
CESoPSN – Pseudowire using the CESoPSN protocol
SAToP – Pseudowire using the SAToPSN protocol
Peer IP Address Displays the pseudowire destination IP address (the peer IP address)
Next Hop MAC Address Displays the MAC address of the next port on the path to the destination (the
next hop MAC address)
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)
Displaying Pseudowire Diagnostic Statistics
You can display, for each pseudowire, the desired diagnostic statistics view:
• Current 15-minute interval (interval 0)
• Any previous 15-minute interval within the last 24 hours, for which valid
performance data exists
• Total for the current 24-hour interval.
³ To display diagnostic statistics data for pseudowires:
1. Navigate to Monitoring > Applications > Multi-Service over PSN > PW screen,
and select Statistics.
2. On the Statistics screen, select Intervals.
3. The Intervals screen displays the number of the first pseudowire, the number
of the I/O slot on which it is terminated, and an interval selection menu. To
select another pseudowire you can either specify its index number, in the
range of 1 to 640, or sequentially scroll forward or backward by typing F or B.
Unused index numbers are automatically skipped.
4. Select the desired display view:
1. To display statistics for the current 15-minute interval, select Current
(15 min).
