Configuring Framing Overhead

The interface framing overhead feature determines whether the MaxCR of a physical interface conforms
to the actual physical line rate, including framing overhead. By default, the unframed rate is used for
determining the MaxCR.
When framing overhead is considered, the MaxCR is less than the unframed rate and some previously
configured connections might not be established.
framing modes, with and without framing overhead configured.
