Description: The number of MPOA Imposition Replies transmitted with an MPOA CIE Code of 0x85, `Unsupported MAC Layer encapsulation'. Discontinuities in the value of this counter can occur at re-initialization of the management system, and/or re-initialization of the MPC, and at other times, as indicated by the value of mpcDiscontinuityTime.

What is mpcStatTxMpoaImpReplyUnsupportedMacEncaps?

This counts Cache Imposition Replies this MPC sent with CIE code 0x85, meaning it rejected the request because it doesn't support the requested MAC-layer encapsulation. It's a configuration-mismatch indicator on the local client's encapsulation support.
