ZXR10-TCP-MIB

Description: Monitors ZTE ZXR10 TCP connection table, state, endpoints, and transport-layer performance 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.

This is a ZTE-specific MIB for the ZXR10 (ZXROS) router/switch software family, focused on monitoring TCP transport-layer state on the device itself. It exposes data on active TCP connections, their endpoint addresses and ports, connection state (e.g., established, listening, closing), and transport-layer performance statistics such as segment counts and retransmissions. Its monitoring value is device-level software/service health: administrators use it to confirm that management-plane services (SSH, Telnet, SNMP-over-TCP, etc.) have healthy TCP sessions, detect abnormal numbers of half-open or stuck connections that could indicate a scanning attempt or resource leak, and track retransmission counts as an early indicator of network path problems affecting the device's own control-plane communication. It closely parallels the standard TCP-MIB (RFC 4022) but is implemented as a ZXROS-specific module, likely for platform-specific extensions. It is typically deployed by network engineers diagnosing management-plane connectivity or TCP-level anomalies on ZXR10 routers and switches. Network engineers evaluating or troubleshooting this functionality can download the ZXR10-TCP-MIB file directly to load it into their MIB browser.

An engineer polls the TCP connection table on a ZXR10 device to check for an unusually high number of connections in a half-open state, which could indicate a SYN-flood style probing attempt against the device's management interface. Elevated TCP retransmission counters correlated with a specific remote management session would point to a network path issue between the operator's console and the device rather than a device-side fault. No sample objects were present in the source extract, so exact table/object names cannot be confirmed here.
