What Is RADLAN-SOCKET-MIB?
RADLAN-SOCKET-MIB is a private Radlan/Marvell MIB module that monitors TCP/UDP socket usage and connection state on the switch's management CPU. It exposes a table of active sockets with their type, current state, blocking mode, and uptime. This is a software-status monitoring MIB, used to check the health of the device's internal networking stack and management-plane services by revealing how many sockets are open, in what state, and for how long. It is a vendor-specific extension with no notable dependency on standards-track MIBs, reflecting internal OS/firmware socket table state. It is typically used by vendors or advanced administrators for diagnosing management-plane connectivity or resource exhaustion issues on Radlan/Marvell-based switches through RADLAN-SOCKET-MIB SNMP monitoring.
IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-SOCKET-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
- active socket count
- socket type (TCP/UDP)
- socket connection state
- socket blocking mode
- socket uptime
Supported Devices
- Radlan/Marvell-based managed switches
Monitoring Examples
An administrator would poll rlSocketTable entries, keyed by rlSocketId, to inspect rlSocketType, rlSocketState, and rlSocketUpTime, looking for sockets stuck in an unexpected state for an abnormally long uptime. A large or growing number of table entries could indicate a socket leak in a management service, while many sockets in a CLOSE_WAIT-like state might point to an application failing to close connections properly.
