Description: Monitors Xylan OmniSwitch DS3/T3 interface framing parameters and performance monitoring statistics.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is XYLAN-DS3-MIB?
XYLAN-DS3-MIB is a Xylan (later Alcatel) proprietary MIB (extending the standard DS3-MIB framework) reporting DS3/E3 physical-layer status on Xylan OmniSwitch equipment. Its port-configuration table, keyed by slot/port, records interface type, TC sublayer, PLCP status, FEAC (Far-End Alarm and Control) state, NAT usage, receive/transmit/expected payload type, a time marker, transmit/receive/expected trail-trace ID, line status, and payload scrambling, while a statistics table reports loss-of-signal, out-of-frame, and AIS events. As a configuration/performance MIB it lets an administrator confirm a DS3 port's payload-type and trail-trace-ID matching between near and far ends, and watch for LOS/OOF/AIS alarm events. It is deployed on Xylan (Alcatel) OmniSwitch equipment with DS3/E3 interfaces. Engineers can download the XYLAN-DS3-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in XYLAN-DS3-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Xylan (Alcatel) OmniSwitch equipment (DS3/E3 interfaces)
Monitoring Examples
An administrator checks dsx3PortConfigRxPayloadType against dsx3PortConfigExpectedPayloadType to catch a payload-type mismatch causing a DS3 circuit alarm on a Xylan OmniSwitch.
What Can Be Monitored
- DS3 payload-type/trail-trace matching
- LOS/OOF/AIS alarm events
