AFAIK, it's not possible to get collisions on a serial line. I remember
someone saying something about this being an example of Cisco reusing code
in their IOS, i.e. using the same ouput routine for both serial and ethernet
lines therefore it shows collisions even though it's not possible to get
A serial line is a point-to-point link. Collisions are only possible on a
shared medium, such as ethernet.

Not to my knowledge.
Collisions are only relevant to contention based
technologies the most common being CSMA/CD (Collision
Sense Multiple Access with Collision Detection) as
defined by the IEEE in 802.3. Serial links do not fit
this bill as they have separate Tx and Rx pairs and
therefore operat

Theoretically, it is impossible to get collisions on a
serial line. LAN bus architecture experiences
collisions because two devices can send frames to the
bus at the exact same time. Serial interfaces transmit
on a frequency if you will. This means that the frames
will pass each other even when se
No, it's not possible. Cisco programmers just got a bit lazy and didn't
remove that line from the "show int serial" output, which is based on the
"show int ethernet" output.

If they pass each other, that's the opposite of a collision.

Phil,
I belive that the CS in CSMA stands for Carrier Sense.
