 8-11

8000-A2-GB20-20

November 1997

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.

3. Check to see if there are too many users on a single

Ethernet.
