All registers in MVTX2600AG can be modified through this synchronous serial interface.
2.7 Stacking
The MVTX2604 supports expanded port count by providing stacking capabilities. The Gigabit port is used as the
link between boxes, and each Gigabit port can be accelerated to 2 Gpbs if desired (in conjunction with ZBT memory
domains at 125 MHz). If both Gigabit ports are used for this purpose, this provides a total of 4 Gbps of bandwidth
between devices.
In addition to a standard back-to-back configuration of devices, the MVTX2604 also provides more powerful
stacking alternatives:
Unidirectional ring configuration. Up to 32 devices. Devices are connected by one Gigabit link, which can be
accelerated to 2 Gbps, if desired. Flow control cannot be enabled in this configuration, because of the
inherent inefficiency in sending flow control messages upstream in a unidirectional ring.
Bidirectional ring configuration. Up to 32 devices. Devices are connected by two Gigabit links, forming two
rings, one clockwise and one counter clockwise. The total outgoing bandwidth can be as much as 4 Gbps.
Flow control may be enabled in this configuration. The outgoing direction of a packet (clockwise or counter
clockwise) is selected using a hash key for load distribution. The hash key can be a function of source MAC
address, destination MAC address, both MAC addresses, or source port. This configuration provides fault-
tolerance when one of the stacking links fail.
