Diagnostics and Troubleshooting

Slow Performance

PROBLEM: Performance is slow.

ACTION: 1. Verify that there are enough buffers on the System Info screen (see Monitoring → Card Status (B-A) in Chapter 7).

2.Check the Ethernet Statistics screen for excessive Cycle Redundancy Check (CRC) errors (see Monitoring → Physical Layer (B-B) in Chapter 7).

Excessive Collisions

PROBLEM: Excessive collisions on an Ethernet port.

ACTION: 1. Determine if your network is too large or long (single

Ethernet cable or end-to-end cable).

2.Check to see if there are too many repeaters.
