Table 3-17	Crossbar Switching Fabric Information
Field		Description
Crossbar Switching Fabric		Physical and configuration information about the module:
		Active slot—Indicates the slot number of the active switching fabric
		module. A value of zero indicates that the active switching fabric
		module is either powered down or not present in the chassis.
		Backup slot—Indicates the slot number of the backup switching fabric
		module. A value of zero indicates that the backup switching fabric
		module is either powered down or not present in the chassis.
		Bus Only Mode Allowed—Determines the value of each module. If set
		to True, each and every module is allowed to run in bus-only mode. If
		set to False, none of the modules are allowed to run in bus-only mode.
		(All the non-fabric capable modules will be powered off.) Absence of
		fabric module results in all the fabric capable modules being powered
		off.
		Truncated Mode Allowed—Indicates whether truncated mode is
		administratively enabled on the device or not.
Module Switching Mode		Indicates switching mode of the module:
		busmode—Module does not use fabric. Backplane is used for both
		lookup and data forwarding.
		crossbarmode—Module uses the backplane for forwarding decision
		and fabric for data forwarding.
		dcefmode—Module uses fabric for data forwarding and local
		forwarding is enabled.
Module-Channel		Module slot number
Module-Status		Status of the fabric channel at the module
Fabric Status		Status of the fabric channel at the slot
Speed (MB)		Speed (MB/second) of the module
Module-Channel		Channel for the module
In Errors		The total number of error packets received since this entry was last
		initialized.
Our Errors		The total number of error packets transmitted since this entry was last
		initialized.
Dropped		The total number of dropped packets transmitted since this entry was
		last initialized.
In Utilization (%)		Input utilization of the channel for the module.
Out Utilization (%)		Output utilization of the channel for the module.
