Cross Bar Mode Configuration

Device > Configure > Cross Bar Mode Configuration

This dialog box provides cross bar mode configuration information on the device.

Note: To support this feature the device should have a Sup2 module installed.

The following information appears:

Cross Bar Fall Back Mode (cc6kxbarFallbackMode)

Cross Bar Truncated Mode (cc6kxbarTruncatedModeAllowed)

Truncated Mode (cc6kxbarTruncatedModeOper)

Force Bus Mode (cc6kxbarForceBusMode)


Cross Bar Fall Back Mode (cc6kxbarFallbackMode)

Controls system fallback to bus mode after the loss of a switching fabric module. There are two possible values:

true—When the last fabric card is removed, the system automatically adjusts the switching mode of supervisor and line cards without resetting the system. With this feature enabled, the switch might lose traffic while it is changing the switching mode.

false—All of the ports in the system are disabled when the last fabric card is removed.


Cross Bar Truncated Mode (cc6kxbarTruncatedModeAllowed)

Determines the value of cc6kxbarModuleModeSwitchingMode for each module. There are two possible values:

true—The value of cc6kxbarModuleModeSwitchingMode for all fabric capable modules present in the system is crossbarmode.

false—Truncated mode is not allowed.


Truncated Mode (cc6kxbarTruncatedModeOper)

Indicates whether truncated mode is enabled on the device. Regardless of the value set for this object, the value of cc6kxbarModuleModeSwitchingMode for all fabric capable modules present in the system is crossbarmode.


Force Bus Mode (cc6kxbarForceBusMode)

Indicates whether affected modules are forced into bus mode. There are two possible values:

true—All affected modules are reloaded and booted up as non-fabric capable modules with a cc6kxbarModuleModeSwitchingMode value set to busmode.

false—All affected modules are reloaded and booted up with the default value of cc6kxbarModuleModeSwitchingMode set.
