Data Sheet
For Chip 1
Don’t Care
Example 2: Mirroring port 1 to port 12 and Mirror receiving direction.
For Chip 0
Set APMR[11:0]= 0x002Mirrored port = 1
Set APMR[12]=0 Local mirrored port
Set APMR[13]=1Receiving mirroring
Set APMR[14]=0Port 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]=1Port 13 is the mirroring port
Example 3: Mirroring port 1 to MII Mirroring port Mirror receiving direction.
For Chip 0
Set APMR[11:0]= 0x002Mirrored port = 1
Set APMR[12]=0 Local mirrored port
Set APMR[13]=1Receiving mirroring
Set APMR[14]=0Port 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: The CPU needs to find out the speed of the mirrored port and configures the mirroring port to the same
speed.
14.0 Virtual Local Area Networks (VLAN)
14.1 Introduction
A Virtual LAN (VLAN) is a logical, independent workgroup within a network. The members in this workgroup
communicate as if they are sharing the same physical LAN segment. VLANs are not limited by the hardware
constraints that physically connect traditional LAN segments to a network. As such, VLANs can define a network
into multiple logical configurations.
