I have setup a frame-relay connection between two nodes A and B using two routers and a third router configured as a frame-relay switch. I have connected a WAN analyzer between the router of node A and frame-relay switch. My WAN analyzer shows Misaligned Frame errors (though they are very small). But when I look at the router and frame-relay switch they show Zero errors. PING and DATA flow smoothly.
So my questions are...
(A) Whether a misaligned frame can occur without FCS error. If yes, then what are the conditions?
(B) Why this error is not shown in the router or frame-relay switch interface?
