This is the conceptual row (entry) definition for the classic MIB-1 Interfaces Table (ifTable), representing one row of per-interface statistics and status such as type, speed, and operational state; the source MIB provides no DESCRIPTION text for this row object beyond its SYNTAX and table linkage. Network management tools use this row type to walk the interfaces table and retrieve per-interface counters and status for every physical or logical interface on the device. For illustration, walking this table on a router would return one row per interface, such as an Ethernet port or serial link, each with its own operational status and traffic counters.
