ACS 5.x Steps To perform the bulk import of MAC address/IP Address in the End Station Filter
Note: There is no option given to bulk import the MAC address or IP address in the end station filter.
Here is the workaround to do the same
(Click on create and check the end station MAC, enter the same then click on Ok)
Now here you can Paste the rest of the MAC and copy the –ANY- in the destination MAC address column, once done save the .CSV file.
Now you can see the MAC address imported on the ACS in end station filter.
