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.
speed Integer value that configures the speed (in Mbps) of the connection between
your Server Switch and a Fibre Channel device or Ethernet device. For Fibre
Channel, enter 1000 for 1 Gbps or 2000 for 2 Gbps.
