What Is CTRON-SFPS-SIZE-MIB?
CTRON-SFPS-SIZE-MIB is a Cabletron (CTRON) enterprise MIB reporting internal scaling/sizing parameters for the SFPS internal service framework on Cabletron networking equipment. It exposes a table (sfpsSizeServiceTable/Entry) listing internal named services (sfpsSizeServiceName, sfpsSizeServiceId) along with configured element size, desired versus granted resource allocations, allocation increment, total bytes consumed, and call counts. It is used to monitor internal software resource utilization — essentially memory/table-size allocation health for internal switch services — letting an operator see whether a given internal service received its desired resources (sfpsSizeServiceDesired vs sfpsSizeServiceGranted) or is running short, and check sfpsSizeServiceRtnStatus for allocation errors. There is no strong external MIB dependency evident; this is an internal diagnostic/introspection MIB specific to Cabletron's SFPS software architecture. It was typically used on Cabletron switches for internal capacity-planning and diagnostic purposes by support engineers troubleshooting resource exhaustion issues. Network engineers evaluating or troubleshooting this functionality can download the CTRON-SFPS-SIZE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-SFPS-SIZE-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
- Cabletron (CTRON) switches
Monitoring Examples
A support engineer troubleshooting a resource-constrained switch would poll sfpsSizeServiceTable entries, comparing sfpsSizeServiceDesired against sfpsSizeServiceGranted for a given sfpsSizeServiceName to see if that internal service failed to get its requested memory allocation. A non-zero sfpsSizeServiceRtnStatus combined with a high sfpsSizeServiceNbrCalls would point to a service that is being starved of resources or repeatedly retrying allocation.
What Can Be Monitored
- internal service resource allocation (desired vs granted)
- service element size and total bytes consumed
- allocation call count
- allocation return/error status
