Brocade Communications Systems 804 manual Speed, Dfsize, Topology

B port

--disable	Disables the physical port, if currently enabled. This is a destructive operation
	and affects normal operation of the port. The port is taken offline, all remote
	FCP sessions are logged out, and all outstanding I/Os are terminated. You are
	prompted before disabling occurs.
port_id	Specifies the ID of the port you want to disable.
--stats	Displays the physical port-level statistics.
port_id	Specifies the ID of the port for which you want to display statistical
	information.
--statsclr	Clears port-level statistics.
port_id	Specifies the ID of the port for which you want to clear statistical information.
--query	Queries and displays port-related details for a port.
port_id	Specifies the ID of the port for which you want to display information.
--speed	Queries or sets the port speed. The port speed can be changed dynamically
	(when the port is enabled). If the port is disabled, the new port speed setting
	takes effect when the port is re-enabled.
port_id	Specifies the ID of the port for which you want to set the port speed.
1248auto	Specifies the port speed. Possible values are auto (to auto-negotiate the
	speed) and 1, 2, 4, 8 speeds.
	Note: The 1 Gbps speed is not valid for an 8 Gbps HBA (825, 815) and the 8
	Gbps speed is not valid for a 4 Gbps HBA (425, 415). All speeds are valid for a
	mezzanine card (804).
--dfsize	Queries or sets the port’s maximum receive data field size. If you do not
	specify a value, the current receive buffer size displays.
	Note: The new receive data field size takes effect when the port is re-enabled.
port_id	Specifies the ID of the port for which you want to set the data field size.
df_size	Indicates the maximum supported receive data field size, in decimal value. If
	set to auto, the driver default value displays. Possible values are 512, 1024,
	2048, and 2112. If set to ‘auto,’ the default value is used, which is 2112.
--topology	Queries or sets the port topology. The port topology can be changed
	dynamically (when the port is enabled). If the port is disabled, the new
	topology setting takes effect when the port is re-enabled.
port_id	Specifies the ID of the port for which you want to display or set the topology.
autop2p	Specifies the topology type. Supported topology modes are as follows:
	• auto - auto-discovers the topology
	• p2p - point-to-point
	• loop - loop mode
	Note: The topology setting will take effect after the port --disable and
	port --enable commands are executed.
