    Morning

    Can anyone tell me if it is possible and how to set up a "Copy Port" on a 8212zl Switch.

    Thanks

    if by "copy port" you want to send traffic going in and/or out of a specific port (or vlan group of ports) to a different port where an analyzer [such as wireshark] is connected, then here it is:

    step 1: 'mirror 1 port b24' this is the port where wireshark is

    step 2: 'interface a1 monitor all both mirror 1' this is the port of "interest" or the data you want to capture

    see the following link for more details: http://cdn.procurve.com/training/Manuals/3500-5400-6200-6600-8200-MCG-Sept09-B-Monitor.pdf

    awesome, thanks.

    Now the fun part.....can I mirror multiple ports to one port? In other words I want to capture the traffic from 8 ports on my mirror port.

    Cheers

    beware on heavily loaded ports.
    if you want to capture 8 ports both send and receive (full-duplex), you generate 16-times as much traffic on the analyzer port!
    result will be that packets will be dropped!
    (only to the analyzer port not real traffic).

    So your captured-data may not represent the real data on the originating ports.
