Hi @haiyang 
In case any queue is not enabled for a port, the forwarded frame which is assigned to this queue is dropped.

hi，

thanks reply ，i see your point！

and the second question ，how to set 

the phy address for port0 and port1, when they set to phy mode？

in my memory，the SJA1105P  can set address through some config pin，but the 

SJA1105TEL have no these pin

best wish

PHY address is for SMI bus. This can be set on PHY like TJA110x, for example and it is used for host CPU to communicate with the PHY. SJA1105 working in PHY mode (MAC-MAC) doesn't have SMI and doesn't need such address.
