In response to raj. In response to Leo Laohoo. Thank you SIR, Every day I am getting more errors and every 10 minutes I was cleared the errors but i don't know the exact solution because I am alone.

Please find the below details 1. Could you please try to change if you have brand new RJ45 cable , pls change it. In response to chintalamuniraju. Thank you for your Reply, Give some time I will change the proper things and let you know.

And if I want to contact in future, How I will contact to you? Regards, Raj raj nextweb. Then how to resolve this issue? Please help me out. To hard set the speed and duplex settings, issue the duplex and speed commands specifying the desired settings. Never mix a hard set and an auto command on the same interface. For example, the speed auto and duplex full commands should never be issued on the same interface. On Cisco set-based CatOS switches, there is only one command used to change the port speed and duplex settings to auto.

In CatOS there is not a command to change the duplex setting to auto, so. If the speed and duplex settings are correct, yet the CRC or runt counters continue to increase, perform these steps:. For more information on port counters and possible solutions, paste your show command output into the Output Interpreter.

The 5-minute input and output rates should be used only as an approximation of traffic per second during a given 5-minute period.

These rates are exponentially weighted averages with a time constant of 5 minutes. A period of four time constants must pass before the average will be within two percent of the instantaneous rate of a uniform stream of traffic over that period. Compare with ignored count. Broadcast storms on Ethernet networks and bursts of noise on serial lines are often responsible for no input buffer events. Received x broadcasts Total number of broadcast or multicast packets received by the interface.

Other input-related errors can also increment the count, so that this sum might not balance with the other counts.

CRC Cyclic redundancy checksum generated by the originating station or far-end device does not match the checksum calculated from the data received. On a serial link, CRCs usually indicate noise, gain hits, or other transmission problems on the data link. On a serial line, this is usually the result of noise or other transmission problems.

Broadcast storms and bursts of noise can cause the ignored count to be increased. This usually indicates a clocking problem between the serial interface and the data link equipment. This might never be reported on some interfaces. Note that this might not balance with the sum of the enumerated output errors, as some datagrams can have more than one error, and others can have errors that do not fall into any of the specifically tabulated categories.

This usually is the result of an overextended LAN Ethernet or transceiver cable too long, more than two repeaters between stations, or too many cascaded multiport transceivers.

Some collisions are normal. A packet that collides is counted only once in output packets. This can happen if packets queued for transmission were not sent within several seconds' time.
