Brief Analysis of vswitch Security Settings

Brief Analysis on the security settings of vswitches recently some popular security settings are available on the vswitch market. I have summarized several popular security settings of vswitches and hope to help you.
Function 1: Traffic Control of the traffic control switch prevents abnormal bandwidth load of the switch due to excessive traffic of broadcast data packets, multicast data packets, and unicast data packets with incorrect destination addresses, it also improves the overall efficiency of the system and ensures the safe and stable operation of the network.
Function 2, L2-L4 layer filter now most of the new switches can be achieved through the establishment of rules to achieve a variety of filtering requirements. Rule settings can be set in two modes: MAC mode, which can effectively isolate data based on the source MAC or destination MAC, and IP Mode, data packets can be filtered through the source IP address, destination IP address, protocol, source application port, and destination application port. The established rules must be appended to the corresponding receiving or transmission port, when the port of the vswitch receives or forwards data, it filters packets according to the filter rules to decide whether to forward or discard the data. In addition, the vswitch performs logical operations on the filtering rules through the hardware "logical and non-Gate" to determine the filtering rules, without affecting the data forwarding rate.

Function 3: Syslog and Watchdog switches send user-defined expected information, such as system errors, system configurations, status changes, periodic status reports, and system exit, to the log server, based on this information, network administrators can learn about the operation status of the device, detect problems early, and configure and set up and troubleshoot problems in a timely manner to ensure the safe and stable operation of the network.
Watchdog sets a timer. If the timer does not restart during the specified interval, an internal CPU restart command is generated to restart the device, this function enables the switch to automatically restart in case of an emergency or accident, ensuring network operation. Author lijing88109
