Description: The number of network interfaces (regardless of their current state) present on this slot.

What is cnt2IfNum?

This Integer32 reports how many network interfaces are physically present on the slot identified by cnt2IfNumIndex, regardless of whether those interfaces are currently up. An administrator uses it to audit how many ports a given line card actually exposes, independent of their operational state. For example, cnt2IfNum reading 4 for slot 7 tells the admin to expect four rows describing that slot's interfaces even if some of them are currently down.
