Telesyn Service Guide (Optimizing Video Services)
In the NMS, thresholds are set in the Ether-like Port Management form, using the Port Thresholds tab. Setting the
threshold invokes SET PORT command above. To enable the NMS to monitor for a threshold trap and to report
this at the NMS as an alarm, select the Configured Collection Node and select Edit -> Add Polling Objects to
have the NMS poll for the statistic, set a threshold, and create an alarm. Refer to the NMS Administration Guide.
3.3.5.3 Fast Ethernet and Fiber-based Interface Monitoring
The following thresholds and counters are especially important to monitor the port for problems or potential
problems.
3.3.5.3.1 Fault Counts
Fault Counts are monitored by the system and recorded in port fault counters. They are:
PKTS512TO1023OCTETS The total number of packets (including bad packets) received that were between
512 and 1023 octets in length inclusive (excluding framing bits but including FCS
octets
PKTS64OCTETS The total number of packets (including bad packets) received that were 64 octets
in length (excluding framing bits but including FCS octets).
PKTS65TO127OCTETS The total number of packets (including bad packets) received that were between
65 and 127 octets in length inclusive (excluding framing bits but including FCS
octets).
UNDERSIZE The total number of packets received that were less than 64 octets long (excluding
framing bits, but including FCS octets) and were otherwise well formed.
TABLE 3-16 Port Counter Faults (SHOW INTERFACE=(SLOT.PORT) FAULTCOUNT)
Counter Meaning
Loss of Link Keeps track of the number of times a loss of link condition occurred on the given
interface. The counter will wrap
Loss of Signal Keeps track of the number of times a loss of signal condition occurred on the given
interface. The counter will wrap
Loss of Frame Keeps track of the number of times a loss of frame condition occurred on the given
interface
Peer Not Present Keeps track of the number of times the modem goes offline.
