NOTE: Speeds below 1000 Mbit/s are allowed only if the MTU size is 1500 bytes or less (Jumbo
Frames disabled, as described in Section 3.7 (page 29)).
The 1000 Mbit/s FD speed is not supported with gelan devices.
For more detail about configuration rules and exceptions, see your driver's nwmgr_driver(1m)
manpage.
Gigabit 1000Base-SX cards
For 1000Base-SX cards, the speed is fixed at 1000 Mbit/s in full-duplex mode. The only adjustable
setting is for autonegotiation. As shown in Table 9 (page 26), there is a specific configuration file
parameter for setting autonegotiation. The nwmgr command uses the speed parameter to set
autonegotiation.

10 Gigabit cards
All 10 Gigabit Ethernet LAN cards operate at 10 Gbit/s in full-duplex mode. The speed is not
settable. Some 10 Gigabit Ethernet LAN cards support 1000Base-SX in addition to 10 Gbase-SX.
To obtain the 1000 Mbit/s speed, the 1000Base-SX cards need to be connected to an Interconnect
Gigabit pass-thru module, for example.
