Temporary handling of intermittent server exceptions and network interruptions

Temporary handling of intermittent server exceptions and network interruptions

In recent days, the company's servers always report that the server cannot be connected. However, the ping from the server in the same vlan has been normal. However, machines in other CIDR blocks cannot be connected after a period of time. After the server is restarted, the server can be connected normally.

After the switch connected to the server is changed, the phenomenon remains unchanged. The problem is that the network cable is also changed and directly connected to the core switch.

This is like an arp virus. The anti-virus software installed with arp on the server has no response and no virus is found. Patch the system again, and the problem persists. If you run arp-d and ping again, the ping will be successful.

There is a holiday, and no one can restart the server in the middle. I want to take a countermeasure First, write a batch processing command regularly, and regularly execute the arp-d command.

@ Echo off: aarp-d @ ping-n 600 127.0.0.1> nul 2> nul goto
