Question

A user reports slow file transfers between their workstation and a server. On the access switch port connecting the workstation, you run 'show interfaces' and notice the port is administratively up and line protocol is up, but the counters show an increasing number of late collisions and runts. The port is configured for 'speed 100' and 'duplex full'. What is the MOST likely cause of this problem?

Accepted Answer

The workstation NIC has auto-negotiated to half duplex, creating a duplex mismatch with the switch port set to full duplex

Answer

The cable exceeds the 100-meter maximum length for copper Ethernet, causing signal attenuation

Answer

The switch port and workstation are both set to full duplex, so no collisions can occur on the link

Answer

The server is using UDP instead of TCP, so lost frames are not being retransmitted
