Usage Guidelines
Platform Availability:
Cisco SFS 3001, Cisco SFS 7000, Cisco SFS 7008, Cisco SFS 3012, Cisco 4x InfiniBand Switch Module
for IBM BladeCenter
Privilege Level:
Unrestricted read-write user, Fibre Channel read-write user, Ethernet read-write user, InfiniBand
read-write user.
Fibre Channel:
The speed of a connection does not necessarily match the speed that you configure. If your connection
cannot physically connect at the speed that you specify, the connection runs at a slower speed that your
Server Switch automatically detects. As soon as a physical change makes your speed setting possible,
the connection will run at the speed that you specified.
Note
You cannot manually configure connection speed you enable auto-negotiation. Enter the
no auto-negotiate command before you manually configure connection speed.
Ethernet:
The speed command sets the administrative speed (the speed that you want) only. Self-detection
determines the actual speed, which depends on the capabilities of the connection. You must disable the
auto-negotiation feature to manually configure speed.
