SMON is the common abbreviation for the Switch Network Monitoring Management Information Base (MIB) system defined by the Internet Engineering Task Force (IETF) document RFC 2613.
SMON is a set of MIB extensions for RMON that allows monitoring of switching equipment from a SNMP Manager in greater detail. The supported MIB tables are described in Supported Standards, Protocols, and MIBs; smonPrioStatsControlTable and smonPrioStatsTable cannot be supported due to hardware limitations.
Note
When you delete all the mirroring filters through the portCopyConfigTable, the mirroring is disabled automatically.
