What Is NSC-TCP-EXCEL-MIB?
NSC-TCP-EXCEL-MIB is Network Systems Corporation's proprietary MIB for TCP/IP acceleration and performance features on its Excel platform, historically used for mainframe channel extension and WAN acceleration links. It exposes configuration and performance data related to protocol acceleration and TCP session handling over those extended links. From a status-monitoring perspective it is oriented toward software/performance health: TCP session/connection counts and throughput-related performance counters would be the primary indicators of link health rather than physical component sensors. No object list was available in the source, so this profile is inferred from the module's stated purpose rather than confirmed object names. It was deployed in legacy WAN channel-extension environments connecting mainframe or SNA sites over accelerated TCP/IP links. Engineers can download the NSC-TCP-EXCEL-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NSC-TCP-EXCEL-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.
What Can Be Monitored
- TCP session/connection count
- acceleration throughput performance counters
- protocol acceleration configuration status
Supported Devices
- Network Systems Corporation Excel platform (WAN/channel extension device)
Monitoring Examples
No sample objects were provided for this module, so a concrete polling scenario naming real objects cannot be constructed; a realistic use, consistent with the module's stated purpose, would be tracking TCP session counts and acceleration throughput counters to detect a degraded or saturated channel-extension link.
