Port Numbering
The port ID consists of port type (Gigabit Ethernet for Gigabit ports and Fast
Ethernet for 10/100 Mbps ports), unit number (1, 2, or 3) and port number (1-2
for Gigabits, 1-4 for the 6 port base and 1-8 for all others). Gigabit Ethernet is
abbreviated as Gi and Fast Ethernet as Fa.
The following table shows, as an example, port numbering for the 26-port
Stratix 8000 switch configuration containing the following:
• One 10-port base switch
• One copper expansion module
• One fiber expansion module
