Hello everyone,
I recently have a little bit nerves for my job.
You might know about flow control between L3 switch (cat65)
and L3 switch (Cat65).
The following is the diagram. Sorry,
I forgot IOS, so please tell me a basic concept.
Traffic generatorA----Cat65A----cat65B-----Traffic generatorB
100Mbps (Fix) 1G (fiber) 1G (fiber)
.1 .2 .1 .2 .1 .2
192.168.0/24 192.168.1/24 192.168.2/24
If Traffic transmits from Traffic generator B to Traffic generatorA,
burst congestion will happen to Cat 65's output interface.
Because TGA and Cat65A line is 100Mbps.
As a result Cat65A will send Pause Frame to notify
about congestion to Cat65B.
However, Cat65s didn't send and receive Pause frame at all.
The purpose is to confirm flow control specification.
Could you tell me some tips to solve problem how I can see Pause Frame.
Yours sincerely,
Isao Nakashita
