Øyvind, I was referring to the IXF440 manual, this is a promiscuous MAC, the ethernet MAC address is only used for flow control, not to filter packet reception.

Hi, I'm using the ENP-2505 1. Is it possible to get the interface configuration from microcode, such as the ip address given in the ixsys.config? 2. In the StrongARM code, do I have to use crosscalls to get this information from the ingressACE, or is there another way? If no other way, is there an example I could look at on how to use the crosscall? 3. I saw in an ealier post, that the mac addr was in the Physical Address Register, I'm unable to find this in my manuals. Could someone guide me there? -- Øyvind Hvamstad
