I have several questions about this:ġ) Why is Siemens using a DIFFERENT MAC specifically for LLDP ? Why is it not just using the same MAC adress as the interface, which is ALSO unique ? I have not seen ANY single vendor that is using a "new" mac address for LLDP ? This is also disadvantage for Siemens as you will require double the amount of official siemens mac addresses.Ģ) The 802.1AB standard specifically says: "The source address shall be the MAC address of the sending station or port." (section 8.1).
This LLDP protocol of Siemens is breaking communications. This means: one port, one mac address max.
We are a large enterprise and have port-security enabled on our switches.
