Found duplicate mac-address

Hi there!

I have 4 EQ that can be connected on ports 1, 2, 3 or 4, but I am getting error when I try to set it up. Does any one help me? Thanks.

Re: Found duplicate mac-address

Hi,

The problem here is that you are trying to add the same secure MAC address to two different ports, which the switch does not allow. An alternative way of doing this is to apply a MAC access-list to the ports which only permits traffic from the specified source MAC addresses.

Hope that helps - pls rate the post if it does.
