To disable compression on the interface, use the no form of this command. Syntax Description mppc Specifies that the MPPC compression algorithm will be used. Default PPP compression is disabled. PPP encapsulation supports predictor, STAC LZS-DCP, and MPPC compression algorithms. Compression is a means of optimizing traffic by running a data set through specific algorithms that either reduce space or bandwidth required to transmit the data set.
Some algorithms reduce packet header size while others condense data within packets.
MPPC implements an LZ based compression algorithm that uses a compression dictionary to compress PPP packets connecting to Microsoft clients. Compression is performed in software and may significantly affect system performance. We recommend that you disable compression if CPU load exceeds 65 percent. To display the CPU load, use the show process cpu EXEC command. If the majority of your traffic is already compressed files, we recommend that you not use compression.
