4189.0. "Manual Mode Filtering" by KERNEL::FREKES (Like a thief in the night) Tue Jan 28 1997 09:40

    Folks
    
    I know this topic has been done to death so I will keep it short.
    I am setting up address filtering on a DS900EF. 
    I followed the following procedure:
    
    * Clicked on the address filter box, from the switch summary screen.
    * Clicked on the big green "First Aid" sign, to create/add a filter.
    * Selected MAC, and filled in the MAC address.
    * Put all the tiles red.
    
    I then saw the notes on Manual mode etc, and unspecified addresses. 
    
    I have two questions. 
    1. From the procedure described above have I setup a manual mode
    filter? If not, what is the difference?
    
    2. Are the filters, filtering the address off that port, or oreventing
    the address from going through the specified port?
    
    I guess questions 1 & 2 are kind of related?
    
    Regards
    	Steven F.

	Stephen, I'll answer question #2 as it should then be intuitive whether you have set it up correctly or not. Manual mode filtering can be specified on a per port basis. If a port is in manual mode, and a packet is attempting to enter the switch on that port, the packet's source address is compared to the list of addresses you had manually entered for that port. If the address is found in the table, the packet will be forwarded. If the address is not found, the packet is blocked from entering the switch. Now if a packet is attempting to exit the switch on the port that you have manually entered an address, its destination address is compared to the list of addresses manually entered in the table. If a match is found, the packet will be forwarded out the port, otherwise, the packet will be discarded. So, depending on whether a match is found on the source address of an in-bound packet or the destination address of an out-bound packet, manual mode filtering will be applied. Bob
