Configuring Fibre Channel Interfaces
Purpose
Enters configuration mode.
Selects a Fibre Channel interface and enters
interface configuration mode.
Prevents the detection of bit error threshold events
from disabling the interface.
Prevents the detection of bit error threshold events
from enabling the interface.
Purpose
Enters configuration mode.
Selects a Fibre Channel interface and enters interface
configuration mode.
Applies the default operational value to the selected
interface. The operational value depends on the port mode.
The default values are assigned based on the port
capabilities.
Assigns a BB_credit of 5 to the selected interface. The
range to assign BB_credits is between 1 and 64.
Assigns this value if the port is operating in E or TE mode.
The range to assign BB_credits is between 1 and 64.
Assigns this value if the port is operating in F mode. The
range to assign BB_credits is between 1 and 64.
Displays the receive and transmit BB_credit along with
other pertinent interface information for this interface.
Note The BB_credit values are correct at the time the
registers are read. They are useful to verify
situations when the data traffic is slow.
