Restoring a Data Port from an ICX 7750 Trunk in a Live Stack
The
multi-stack-trunk command can be used to remove a stacking port for configuration as a data port.
Use the following procedure in a production environment to reduce the size of a trunk and make an end port in the trunk available for configuration as a data port.
The following example reconfigures a six-port trunk between module 2 of stack units 1 and 2.
- From the active controller for the stack, enter stack-unit configuration mode for a device at one end of the trunk.
- In stack-unit configuration mode, enter the
multi-stack-trunkcommand. Specify the new, smaller port range for the trunk on both ends (stack-unit 1 and stack-unit 2 in the following example). Be sure the port numbers are correct and the size of the trunk is the same on both ends.The end port of the trunk on each stack unit is dropped from the trunk and is available for configuration on each of the units. - Configure one or both of the ports as appropriate.
In the following example, port 2/2/6, which was previously part of a six-port trunk between stack unit 1 and stack unit 2, is ready to configure as a data port.
