  • sh cont ser unsure what sdma and mpsc are

    when doing a show controller serial, with not having an integrated wic, so no sh controller t1 or e1 or sh ser. The only option other than showing the interface is showing the controller serial to determine an error issue. I know that mpsc is a multiprotocol serial controller and that the sdma is an interface, but i was unable to find on cisco site or google, or from ccie, what all this means, like what does "
    109827 sdma_rx_ce" mean. When the interface takes errors it shows an increase in other fields of the show controller but they do not match the interface errors when doing a sh int ser, so they mean something. Also the rxintr and txintr are the byte counts for the interface. Thanks for your help,
