In order to help maintain hygiene across the peering fabric, all peering participant ports are subjected to a standard layer-2 filtering policy to limit frames that are considered unwanted at the peering fabric. Below is a list of frames that are filtered (dropped) by default. This list is revised as necessary.
In general peers are expected to send only IPv4 (0x0800 ), IPv6 (0x86dd ) and ARP (0x0806) ethertypes. Other frames types will be dropped.
Do not send Proxy ARP or link-local Traffic. only send unicast, ARP and IPv6 ND.
Mac Security To keep security at the highest level we implement Layer 2 MAC filtering on the INX-ZA peering fabric. This is to help prevent unauthorised traffic from entering the exchange. Each peering port/bundle is restricted to a single MAC address and is staticlly locked down, meaning it will not learn a new MAC if the old one times out. If you require the MAC on your port to change please email ops@inx.net.za to schedule the time the change will take place and our team will be on standby
