After reading several similar threads I'd like to start a new one. We are seeing increasing output drops on 2960X and 2960S ports in a specific circumstance: A port is connected to a 6961 or 6941, AND the phone is supporting a computer or other device via the phone's relay port. We don't see steady drops (typically none) when a phone is connected by itself, or when some other 10Mb or 100Mb device is connected to the switchport and auto-negotiates a slower speed.
We don't see this problem on 3560's, 3750's, or 3850's. Only 2960S and X models.
Last week I upgraded a 2960X to the latest starred version, 15.2(2)E8, but that had no effect on the situation described above.
Anyone else encountered this problem with 6900 phones and 2960's?
