I can see the cpa traffic ( with "show interface channel " in the router. The question is what is the relation between 2 kind of traffic. What overhead add the x25 encapsulation?</P><P>Thanks.</P><P>Regards</P> Tue, 19 Mar 2002 13:59:01 GMT https://community.cisco.com/t5/server-networking/migration-from-channel-traffic-to-qllc-traffic/m-p/64189#M398 MARCELO MATURO 2002-03-19T13:59:01Z Re: migration from channel traffic to qllc traffic https://community.cisco.com/t5/server-networking/migration-from-channel-traffic-to-qllc-traffic/m-p/64190#M399 <HTML><HEAD></HEAD><BODY><P>A direct channel connection can operate at a theoretical speed of 17 MBytes/sec.
