What Is XYPLEX-LAT-MIB?
XYPLEX-LAT-MIB is a vendor MIB from Xyplex (a maker of terminal servers and network access equipment) for managing DEC's Local Area Transport (LAT) protocol, used historically to connect terminals and printers to VAX/DEC hosts over Ethernet. It would define objects for LAT service-node configuration, such as advertised LAT services, node names, and active session/connection management between terminal server ports and host services. No module description or sample object names were supplied here, so its exact table and leaf structure cannot be confirmed, but by protocol and vendor context its monitoring role would center on software/service status: whether LAT services are being advertised correctly and how many active LAT sessions/connections exist on the device. It likely depends on the device's own interface/port MIBs and possibly DEC's LAT protocol conventions rather than any IETF standard, since LAT is a DEC proprietary protocol. It would be deployed on Xyplex terminal servers in legacy DEC/VAX minicomputer network environments providing terminal and printer access, and administrators maintaining such legacy gear can still find a XYPLEX-LAT-MIB download to load into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in XYPLEX-LAT-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.
Supported Devices
- Xyplex terminal server / LAT-capable network access device
Monitoring Examples
No sample object names were provided for this MIB, so a specific polling scenario cannot be described without inventing object names; in a legacy DEC LAT environment such a MIB would typically be used to confirm a terminal server's advertised LAT services are visible to hosts and that active terminal sessions are being tracked correctly.
