spx cb-configure
Router configuration mode
The
no form of the command removes all CB configuration and is available only when
cb-enable configuration is not present.
The
spx cb-configure command is available only when the control bridge has been enabled on an eligible
router. The router must be an
ICX 7650 or
ICX 7750 device.
In CB configuration mode, zero-touch provisioning can be enabled, and zero-touch-ports can be configured. In addition, multicast E-CIDs, SPX ports, SPX LAGs, and PE IDs can be configured. SPX ports and LAGs can be configured in advance or on live links.
The following example enables 802.1br CB mode and enters CB configuration mode.
ICX7650-48F Router# configure terminal
ICX7650-48F Router(config)# spx cb-enable
