What does "nnn output buffers swapped out" in the show interface serial command mean?
Because I have a problem with one of our serial links in our cisco 7513. It's a point-to-point link using encap ppp
having a 128 kbps rate. Sometime during the day, remote users using the link complain about slow line,
if I check the serial link they are connected to, the "output buffers swapped out" keeps increasing.
What does this mean???
