XYLAN-SONET-MIB

Description: Monitors Xylan OmniSwitch SONET section, line, and path layer performance monitoring counters.

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.

This Xylan Corporation enterprise MIB for OmniSwitch SONET interface cards models performance-monitoring counters at the SONET section, line, and path layers as defined by telecom SONET standards. It exposes granular error and performance counters — such as coding violations, errored seconds, severely errored seconds, and loss-of-signal/frame events — segmented by SONET layer. This is fundamentally a hardware health and link-quality monitoring MIB: it lets an operator detect degrading optical signal quality, framing errors, or physical-layer faults on a SONET interface before they cause an outage. It parallels and extends the standard IETF SONET-MIB (RFC 2558) framework with Xylan-specific current/interval counter tables. It is used in service-provider or enterprise WAN environments where OmniSwitch equipment terminates SONET optical transport circuits. Engineers can download the XYLAN-SONET-MIB file directly to load it into their MIB browser.

No sample objects were available in this MIB source. In general, an administrator would poll the SONET section/line/path current and interval performance counters, such as errored seconds and severely errored seconds, per interface. A rising count of these counters on a given SONET path would indicate a degrading optical link or a failing transceiver.
