ZTE-AN-CLOCK-MIB

Description: Manages ZTE access node clock synchronization sources, timing references, and synchronization status.

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.

ZTE-AN-CLOCK-MIB is a ZTE enterprise MIB for their Access Node (AN) product line, dedicated to managing timing and clock synchronization functionality. It defines objects for configuring and reporting on clock sources, timing references, and synchronization status used to keep the access node's internal clock aligned with a network timing reference (such as a BITS/SSU source or line-derived timing). As a monitoring tool it is squarely focused on a hardware/timing-subsystem health signal: whether the node is synchronized, holdover, or free-running, and which clock source is currently selected, which is critical for services (like TDM or synchronous Ethernet) that depend on accurate clocking. Only conformance group objects (zxAnClockCompliances, zxAnClockGroups) were visible in the available data, suggesting the module also defines standard MIB-conformance structures alongside its clock-management objects. It is deployed on ZTE access node equipment in carrier access networks where synchronization accuracy affects downstream TDM/E1/T1 or SyncE service quality, making the ZTE-AN-CLOCK-MIB MIB a key reference for timing-subsystem monitoring in these networks.

An operator would poll the clock-source and synchronization-status objects on a ZTE access node to confirm the device is locked to its primary timing reference rather than having fallen back to holdover or free-run mode, which would indicate a timing-reference failure upstream. Only the conformance objects zxAnClockCompliances and zxAnClockGroups were present in the sample data, so specific runtime object names cannot be cited here beyond noting that this module defines AGENT-CAPABILITIES-style conformance groups for the clock-management feature.
