Chapter 12 Command Line Interface Reference
interface fc? al-fairness
interface fc? al-fairness
To enable the fairness algorithm (loop priority) on the named Fibre Channel (FC) interface, use the
interface fc? al-fairness command. To disable the fairness algorithm on the named FC interface, use the
no form of this command.
interface fc? al-fairness enable
no interface fc? al-fairness enable
Syntax Description
Defaults The fairness algorithm is disabled on all FC interfaces by default, allowing the switch to have priority.
Command Modes Administrator.
Command History
Usage Guidelines When the fairness algorithm is not enabled for a specific FC interface, the switch receives priority. Use
this command to enable the fairness algorithm for the named interface, removing the switch priority for
that interface.
Note All storage routers in a cluster should be configured with the same interface-specific parameters,
allowing failover of SCSI routing instances to provide consistent performance characteristics.
Examples The following example enables the fairness algorithm on the FC interface named fc6:
[SN5428-2A]# interface fc6 al-fairness enable
The following example disables the fairness algorithm on the FC interface named fc3. The switch
receives priority for traffic on this interface.
[SN5428-2A]# no interface fc3 al-fairness enable
fc? The name of the FC interface for which you are setting this parameter. Valid
values are fc1 through fc8. When you type the interface fc? command, the
CLI lists the interfaces available. You cannot specify a nonexistent
interface.
enable Keyword, required to enable the fairness algorithm on the named FC
interface.
