Is there a limitation in daisy chain with ADIN2111

Question

We are planning to use the ADIN2111 in a daisy chain topology, but we can't find any information about the amount of nodes that can be linked. 
 Is there any information available on this topic?

Hi demjoerchsein , 
 Technically speaking you can connect as many nodes as you can supply MAC addresses on a daisy chain, the limitations will be on your network load/ throughput which depends on the way your network is set-up. If the devices need to be IP addressable then it also rely on the IP assignment of your nodes (whether you use a DCHP server or assign fixed IPs). 
 APL has published some good information on the network load aspect: Ethernet-APL Engineering Guidelines - Ethernet APL 
 Things to consider: 
 
 "Software filter/switching" (i.e. packet forwarding between the 2x ports managed by the host) will increase port-2-port latency 
 Using the ADIN2111 Hardware MAC filtering filter can significantly reduce port-2-port latency (vs. previous point), 
 Data chunks size transmitted to the ADIN2111 will also impact on the system effective throughput ( i.e. larger chunk transmissions reduce the total overhead data) 
 Any heavy software processing required on a host could potentially reduce overall throughput 
 If Media Redundancy is required then a management protocol such as MRP is recommended 
 Cable/Link quality can reduce transmission speed and impact overall throughput
