Problem Description
The DRS function of the high-end AC causes the CPU of the AC to increase
Process Analysis
Note that after the
high-end AC enables the wlan drs enable function (this command will be issued
after clicking the AC-Service Configuration-DRS Deep Packet Detection
Statistics function on the Oasis page to enable it), the hard transfer will not
take effect. In the case of centralized forwarding It will cause the CPU of the
forwarding core to be high. This function corresponds to the dpi service, and
other services such as QOS, packet-filter, etc., are not supported by FPGA and
driver fast forwarding, so high-end ACs, especially under centralized
forwarding conditions, should avoid such configurations.
Solution
Delete wlan drs enable
configuration
