Description: This object reflects an internal state of the port with regard to its ability to learn new addresses. Certain port configurations such as learning time limit, security usage, etc., and some Spanning Tree Protocol states can temporarily prohibit the port from learning. This object is true(1) if the port is allowed to learn. It is false(2) otherwise.

Setting this object to true(1) will fail, if the port is not in normal state.

This object is deprecated.
