RADLAN-SOCKET-MIB

Description: Monitors TCP/UDP socket usage and connection state statistics on Radlan platforms.

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.

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.

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.
