- the document doesnt lead one to believe that full duplex
are not deferred packets anywhere. in fact, in the case of
a sync problem, full duplex may be the problem if you have
set on other interfaces on the wire. is this a subnet
w/mixed duplex devices?
- deferred packets refer to the sending frames, not receiving
XMIT increments this counter when the software is ready to
send a frame but the interface hardware isnt.
- have you checked for broken NICs, or simply too many
stations on the shared medium.

Subject: [nsp] deferred
There is a WS-C2950T-24 with IOS C2950-I6Q4L2-M, Version 12.1(13)EA1
One of its ports is attached to a 10 Mbit Allied Telesyn optical
transceiver, the port is configured for full duplex, speed 10.
The problem is that the packet loss in this link is up to 20%. There
are 0 input or output errors in "sh interface". The only suspicious
counter is "deferred" which is rapidly growing.
What could be the reason ?
I also do not understand how the deferred counter could be growing on a full
duplex link. According to
it should not happen, if I correctly understand the meaning of
Thanks in advance for any input.
