spx cb-configure

Enters 802.1br control bridge (CB) configuration mode, where SPX ports and LAGs are configured.
Syntax
spx cb-configure
no spx cb-configure
Modes

Router configuration mode

Usage Guidelines

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.
