5.2.4 PHY Management Interface
The 98CX8234 includes three separate serial management interfaces (SMI) for management
access to the switch and attached PHY devices. The SMI interface usage and PHY device
connection are listed in
Table 5-3 .
The Switch contains four, IEEE 802.3 clause 22 compliant, Master SMI Interfaces (MSMI) for
managing external Gigabit Ethernet PHY devices. Each MSMI is associated to one of the four
port groups of the switch. This allows the SP to configure the PHY devices and read back PHY
status information via read/write access through 98CX8234.
The Switch contains four port groups, Master SMI Interfaces (MSMI) and IEEE 802.3 clause 45
compliant for managing external 10 Gigabit Ethernet PHY devices that are connected to the
XAUI ports. Each XSMI is associated to one of the four port groups of the switch.
