This notification variable reports the Ethernet link's speed immediately after the detected change, paired with mimosaOldSpeed in the same Ethernet Speed Change trap to show the before-and-after transition. An admin reads this alongside the old-speed value to confirm what speed the link settled at following the change. For example, a trap carrying mimosaNewSpeed of 100 tells the admin the link renegotiated down to 100 Mbps, a downgrade worth investigating if gigabit was expected.
