13.2.2.Processing Procedure
Step 1 Show the port configuration of both parties, and check the working mode of their ports in actual circumstances
Step 2 Check whether there is any wrong statistics in the statistical information about ports.
Step 3 Check whether the making of network cables meets the EIA/TIA 568A/B standard. Network cables can be changed if necessary.
Step 4 Do the test of changing the upstream electric interface.
13.2.3.Typical Cases
1.1.1.73Case 1:
1.1.1.73.1Background
The phenomenon of intermittent
1.1.1.73.2Fault symptom
The phenomenon of intermittent
1.1.1.73.3Analysis and troubleshooting:
Step 1 Check the port modes of the equipment at both ends, they are all the 10/100M
Step 2 View the statistical information of the ports, and find a number of CRC
Error alarms.
Step 3 Upon obtaining the consent from the customer, check the network cables used for the upper connection, it is found that the network cables have not been made according to the standard linear ordering, and only the color labels of both parties are made the same.
Step 4 After we use the EIA/TIA 568B standard linear ordering mode to remake the network cable, the service becomes normal.
1.1.1.73.4Summary
A minute problem can often affect the whole work. A
The standard linear ordering of network cables: Yellowish white, yellow, greenish white, blue, bluish white, green, brownish white and brown, and the same at both ends. This kind of network cables can be used for the connection of 10M/100M lines. While the practice of making the linear ordering of both ends consistent
Note can only applied to the connection of 10M lines. The ports auto- negotiated to 100M, however, is connected using the 10M
network cable, the packets are inevitably to collide, which leads to the intermittent
