Note
The number of connected switches influences the frame delay.
When a frame passes through the CSM 1277, it is delayed by the store and forward function
of the switch
- with a 64 byte frame length by approx. 8 µs (at 100 Mbps)
- with a 1500 byte frame length by approx. 125 µs (at 100 Mbps)
This means that the more CSM 1277 switches that a frame passes through, the higher the
frame delay will be.
