If it is found that there is an error packet of CRC in the Input direction of the interface, it means that there has been or exists the phenomenon of error packet in the upstream packet.

Need to troubleshoot

Solution: check the status of upstream equipment, whether there is packet loss, abnormal optical power and so on.

If it has occurred before, but the data has not been cleared, you need to observe whether the number of packets has increased. If not, you can clear the statistics under the API to avoid unnecessary errors. Clear all the data statistics under the interface by using the command reset count interface XG 0Unitable1.

two。 Check the parameter information of the optical module, there is an exception

The accepted optical power is too low, maybe the optical fiber is not connected properly, or the opposite end does not emit light.

3. The power supply display is not normal

1 PWR2 Present AC Supply 150.00

2 PWR1 Present AC NotSupply 150.00

2 PWR2 Present AC Supply 150.00

AC is AC power supply.

DC is DC power supply

Possible reasons:

The customer is a single power supply and there is no second power supply module.

There is a second power supply, but there is no power on.

It is true that the power supply is down.

4. The running configuration file is inconsistent with the saved configuration file

Display configuration changes

5.SNMP protocol version check

Display snmp-agent sys-info version

SNMP version running in the system:

SNMPv2c SNMPv3

When configuration occurs, multiple versions of SNMP are compatible at the same time and have no effect.

6. Judge whether the operation will affect the business according to the rate reported in the current network.

Display interface GigabitEthernet2/0/12

Last 300 seconds input rate 448792 bits/sec, 62 packets/sec

Last 300 seconds output rate 506664 bits/sec, 71 packets/sec

Add up the packet rates of input and output several times to determine whether there are a large number of services running

7. MAC address drift occurs

Possible reasons:

Client's movement-A simple MAC drift appears in the log at this time, with no effect

However, if there are a large number of MAC drift logs, showing the same mac drift, there may be a two-layer loop, or suffer from *, check the status of stp, MAC drift table

You can configure the maximum number of MAC that can be accessed by configuring the same priority of MAC address that cannot be overridden and statically bound.

8. The veneer is not working properly.
