XYLAN-POS3-MIB

Description: Monitors Xylan OmniSwitch Packet over SONET OC-3 interface parameters and transmission 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.

XYLAN-POS3-MIB is a vendor-specific module from Xylan, later acquired by Alcatel, used on OmniSwitch platforms to manage Packet over SONET (POS) interfaces running at OC-3 (155 Mbps) rates. It is expected to expose interface-level configuration and statistics for POS OC-3 links, such as framing mode, alarm/defect indicators, and transmission counters layered on top of the standard SONET/PPP interface stack. As a monitoring tool it would primarily support hardware/link-status visibility, letting an operator see whether a POS OC-3 interface is up, whether it is reporting SONET-layer alarms or errors, and how much traffic is passing over it. It builds on standard SONET-MIB and IF-MIB conventions for interface indexing and status rather than defining an entirely independent addressing scheme. It would be deployed on legacy Xylan/Alcatel OmniSwitch chassis providing SONET/POS WAN uplinks in carrier or enterprise backbone networks. Engineers can download the XYLAN-POS3-MIB file directly to load it into their MIB browser.

No sample object names were provided for this MIB, so specific object polling cannot be described with confidence; in general, an operator would expect to poll per-interface SONET/POS OC-3 status and error counters, analogous to standard SONET-MIB line/section tables, to detect link-down conditions or rising bit-error rates on the OC-3 circuit.
