ICX 7850 stack configuration overview

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.
1. From the active controller for the stack, enter stack-unit configuration mode for a device at one end of the trunk.
ICX7750-48F Router(config)# stack unit 1
2. In stack-unit configuration mode, enter the multi-stack-trunk command. 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.
ICX7750-48F Router(config-unit-1)# multi-stack-trunk 1/2/1 to 1/2/5 and 2/2/1 to 2/2/5
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.
3. 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.
ICX7750-48F Router(config)# interface ethernet 2/2/6
Error - command not allowed for stacking port: 2/2/6
ICX7750-48F Router(config)# stack unit 1
ICX7750-48F Router(config-unit-1)# multi-stack-trunk 1/2/1 to 1/2/5 and 2/2/1 to 2/2/5
ICX7750-48F Router(config-unit-1)#interface ehternet 2/2/6
ICX7750-48F Router(config-if-e40000-2/2/6)#
