I have 2 clients that A and B. A sends periodic updates to B however B does not receive all updates, I have ruled out routing as some updates are being received and no change of configuration has occured. client A is on a 10 half duplex interface, which has high collisions (collisions are expected on half duplex interfaces). My question is do high collisions on a switchport affect data throughput? apart from the collisions seen the port is clean with no errors. Are there any other checks I can carry out in the meantime while waiting for my App engineers to get back to me?
