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?

Hello,
Collisions do affect the traffic adversly. Depending upon the type of traffic you are sending, TCP might retransmit again (a set number of retransmissions) but UDP will drop the packet. You can use "show controller ethernet-controller
Hope this helps.

Thanks guys, I was kind of hoping the messages would be TCP and therefore retransmit, but I'll change the duplex settings and see if this makes a difference.

You will experience a packet loss and performace issue if it is 10Mb and half duplex mode configured at client end what is the status at switch end,if possible try with auto configuration at both the end switch as well as at client end.
Hope to Help !!
