8.0 Port Mirroring
The port mirroring function is only supported in RMII mode. Using the 4 port mirroring control pins provides the
ability to enable or disable port mirroring, select which of the remaining 7 ports is to be mirrored and whether the
received or transmitted data is being mirrored. The control for this function is shown in the following table.
Table 2 - Port Mirroring Configuration
When enabled, port mirroring will allow the user to monitor traffic going through the switch on output Port 7. If the
port mirroring control pins, Mirror_Control[3:0], are left floating, MVTX1100 will operate with the port mirroring
function disabled.
When port mirroring is enabled, the user must configure Port 7 to operate in the same mode as the port it is
mirroring (autoneg, duplex, speed, flow control).
9.0 Power Saving Mode in MAC
The power saving mode is activated only in RMII mode. MVTX1100 was designed to be power efficient. When the
internal RMII MAC sections detect that the external port is not receiving or transmitting packets, it will shut down
and conserve power. When new packet data is loaded into the output transmit FIFO of a MAC in power saving
mode, the MAC will return to life and begin operating immediately.
When the MAC is in power saving mode and new packet data is received on the RMII interface, the MAC will return
to life and receive data normally into the receive FIFO. This wake up occurs when the MAC sees the CRS_DV
signal asserted.
Using this method, the switch will turn off all MAC sections during periods when there is no network activity (at night
for example), and save power. For large networks this power savings can be significant. To achieve the maximum
power efficiency, the designer should use a physical layer transceiver that utilizes “Wake-On-LAN” technology.
