Hi Steve, There have been moves to unify IXP data in JSON format to describe members at an IXP, and to a certain extent, VLANs and infrastructure.
https://ripe69.ripe.net/presentations/94-1411-ej-ixp-json-api.pdf https://github.com/euro-ix/json-schemas Many exchanges have already implemented this JSON schema. Though the schema allows for MAC address, I am not sure how widely implemented this is yet. For example, while we implement the JSON schema, mac address doesn't show in there yet owing to limitations in the back-end database, though this is hopefully going to be addressed. The only other reliable ways would be to use the ARP table at each IXP connection to map the MAC <-> Peering LAN IP and also ASN. (this can usually be collected via SNMP, for example, though if you are using route servers, may require more effort again.) Combining this with sflow data is another possibility.
