SNMP How to get number of learned MAC addresses on Switch interface>

There is nice c2900PortNumberOfLearnedAddresses table in C2900-MIB, but it's outdated and not supported by modern switches.

Is there similar table for modern switches? Most interested in Catalyst 2960 and 3750.

Fetching whole forwarding table is not a good idea.
