Communication Problems

The most common

A high percentage of faults are caused by cable faults such as loose

problems are cable

connections or inappropriately wired cables.

problems

 

Management PCs using

A management PC using IEEE 802.1Q tagged frames may experi-

IEEE 802.1Q tagged

ence communication difficulties with the switch. To manage the

frames

switch from a PC connected directly to the switch, the PC must not

 

use frame tagging. To manage the switch from a PC with IEEE

 

802.1Q tagged frames, management must be through a device which

 

untags the frames.

Spanning Tree topology

When a change is detected in the Spanning Tree network, the devices

changes

forming the Spanning Tree go into a learning state to determine the

 

optimal routes between network segments. During this learning state,

 

the switch will not forward data traffic.

 

This is a normal occurrence for Spanning tree devices and no reme-

 

dial action is required. However, if the switch goes into the learning

 

state too frequently, the Spanning Tree may be unstable and should

 

be examined and possibly reconfigured.

To troubleshoot

If the POWER LED and the STATUS LED are both on, but one or more

communications problems

of the port STATUS LEDs are off, then:

 

1 Reset the switch using the Reset button.

 

2 Check the STATUS LED for each switch port to which a cable is

 

attached.

VLANs

The use of VLAN policies can lead to unexpected communication

 

problems. If the policies are not designed with care, ports are not able

 

to reach network services. Check your VLAN policies and use the

 

VLAN monitoring to review the VLAN membership for that port or

 

address.
