Refer to the Exhibit. An engineer configured a Cisco Telepresence Server with two Cisco acquired codian devices. Users are reporting that the image looks frozen and audio contains static and is garbled on one of the devices. What is the root cause of the issue?
A. There is mismatch in the port configuration.
B. The input flow control is off.
C. The QoS that is configured on the port is set to FIFO.
D. There are packet drops in the ingress queues.
Agree. ‘root cause’ is the key word
I would say A is the answer. There are packet drops BECAUSE the port is at half-duplex (port mismatch configuration). Packet Drops are an effect of the duplex mismatch (root cause).
