Data Sheet
Example 1: Mirroring port 1 to port 0 and Mirror transmission direction.
For Chip 0
Set APMR[11:0]=0x002; mirrored port= 1
Set APMR[12]=0 ; local mirrored port
Set APMR[13]=0; Transmission mirroring
Set APMR[14]=1; Port 0 is the mirroring port
For Chip 1:
Don't Care
Example 2: Mirroring port 1 to port 13 and Mirror receiving direction.
For Chip 0
Set APMR[11:0]= 0x002; mirrored port= 1
Set APMR[12]=0 ; local mirrored port
Set APMR[13]=1; receiving mirroring
Set APMR[14]=0; Port 0 is not the mirroring port
For Chip 1:
Set APMR[11:0]=0x000
Set APMR[12]=1 ; remote mirrored port
Set APMR[13]=Don't careBit[13] has meaning only in the chip of mirrored port
Set APMR[14]=1; Port 13 is the mirroring port
Example 3: Mirroring port 1 to MII Mirroring port Mirror receiving direction.
For Chip 0
Set APMR[11:0]= 0x002; mirrored port= 1
Set APMR[12]=0 ; local mirrored port
Set APMR[13]=1; receiving mirroring
Set APMR[14]=0; Port 0 is not the mirroring port
For Chip 1:
Set APMR[11:0]= 0x000
Set APMR[12]=1 remote mirrored port
Set APMR[13]= Don't careBit[13] has meaning only in the chip of mirrored port
Set APMR[14]=0Port 13 is not the mirroring port
Note that CPU needs to find out the speed of the mirrored port and configures the mirroring port to the same speed.
