4. CHAPTER 4 Intel Express 10 100 Fast Ethernet Switch 72 General Problems If you re having problems with the switch follow the steps below 1 Verify that your cables are wired correctly This is the most common problem Use a UTP crossover cable to directly connect to a repeater or another switch Use straight through cables when connecting to servers or workstations Try both the MDI and MDI X connectors on port 1 if you re unsure of which cable to use See page 8 for more information 2 Make sure the unit is plugged into a functioning AC outlet Also make sure the voltage setting next to the switch s power receptacle is set correctly In the United States Canada and Japan the setting is 115 In most European and Asian countries it s 230 3 Review the switch s Link LEDs to ensure the ports you believe should be functioning are properly configured and not disabled Also review the Link LEDs of other devices to ensure the ports that should be functioning are properly attached to the switch 4 Make sure devices connected to the switch are operating at the same speed as the switch port Each switch port can be forced to either 10 or 100 Mbps although auto detect is the default Also other devices connected to the switch may be capable of operating at 10 or 100 Mbps See page 66 for information on setting speed 5 If you configured a port for full duplex make sure the device on the other end is configured for full duple
5. Monitoring traffic Use monitoring commands to determine the traffic volume from specific ports or between ports This information helps you determine the network s traffic patterns so you can adjust your network topology for maximum efficiency Make sure you get a good statistical representation of your network Take a reading when users log on in the morning and pull files from servers and another during breaks or when users log off at night any time you think the network is experiencing heavy traffic This gives you a baseline for comparison when problems arise on the network Statistics are generated for the current session Reset counters by using the c1r cnt command warm reset command or by cycling the power In general keep devices that talk primarily to each other on the same segment remember each port is an Ethernet segment For example if a high volume of traffic is forwarded from the CD server on port 4 to the payroll workgroup on port 3 but no other workgroups access the CD server move the server to the hub on port 3 instead of the switch This change may not be efficient however if users from the payroll marketing or finance workgroups also access the CD server Under heavy traffic loading conditions the Console Manager may understate the Ethernet statistical counts You can also use a protocol analyzer to monitor the segment the port is attached to See step 8 on page 72 for configuration details Commands u
