CISCOSB-SOCKET-MIB

Description: Monitors TCP/UDP socket connections and resource usage on Cisco Small Business switch 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.

CISCOSB-SOCKET-MIB is a Cisco Small Business private MIB exposing the device's own internal TCP/UDP socket table, essentially a management-plane view of open network connections and their state on the switch itself. It provides a table of sockets with type (TCP/UDP), current state, blocking mode, and how long each socket has been open. Its monitoring value is software/process-level health—detecting resource leaks (e.g. sockets stuck in a non-closing state), abnormal connection counts, or long-lived sockets that may indicate a hung management process on the device. It has no dependency on external standard MIBs, being a lightweight vendor-specific diagnostic table. It is used on Cisco Small Business switches primarily for low-level troubleshooting of the device's own management/control-plane software, an area where CISCOSB-SOCKET-MIB SNMP monitoring helps administrators spot socket leaks before they degrade the switch's management responsiveness.

An administrator troubleshooting sluggish web-management response would poll rlSocketTable/rlSocketEntry and check rlSocketState for entries stuck in an unusual state, and rlSocketUpTime to spot sockets that have remained open far longer than expected. A growing rlSocketTable with many entries in the same rlSocketType and non-closing rlSocketState would indicate a socket leak in the device's management software consuming system resources.

Manages socket operations and states on Cisco Small Business switches, tracking open sockets by type, state, and uptime.
