stack-trunk

Configures a stack to form a trunk from contiguous links on one side of a stack connection.
Syntax
stack-trunk ethernet port-list
no stack-trunk ethernet port-list
Parameters
ethernet
Specifies Ethernet as the interface type.
port-list
A port range in the form stack-unit/slot/port to stack-unit/slot/port, a list of ports in the form stack-unit/slot/port stack-unit/slot/port, or a combination of ranges and ports.
Modes

Stack unit configuration sub-mode

Usage Guidelines

From FastIron release 08.0.90, the stack-trunk command has been modified to behave as described in this section. For more information on previous command behavior, refer to the Ruckus FastIron Stacking Configuration Guide

The first port of a stack-trunk must be in a valid-stack-port set. Every platform has one or more valid-stack-port sets that define what ports can be configured as stack-ports or stack-trunks.

A linear-topology trunk may allow two contiguous ranges of ports from two different modules.

If the stack-trunk command specifies a port in common with an existing stack-trunk or stack-port configuration, the stack-trunk command overwrites the existing configuration.

Use the no form of the command to remove the stack trunk configuration. The no stack-trunk and the no stack-port commands must include in command syntax an exact match to existing ports.

The stack-trunk command must be configured on the stack units on both ends of the trunk. Use this command in a new environment on the first deployment of a stack.

To enable the stack-trunk command, the primary port in the trunk must be a stacking port in a valid-stack-port set. The valid-stack-port sets are specific to each ICX model.

Adding stack-port or stack-trunk configuration may cause the removal of existing stack-port or stack-trunk configuration if the new configuration is not contained in the same valid-stack-port set.

For more information on valid-stack-port sets for each ICX device, refer to the Ruckus FastIron Stacking Configuration Guide.

Use the multi-stack-trunk command to change a live stack-port or stack-trunk connection. The multi-stack-trunk command changes both ends of the connection simultaneously to avoid breakage.

If adding stack-port or stack-trunk configuration will cause the removal of a live stacking port or stacking trunk, the command entry is denied.

Examples

The following example configures ports 1/2/3 and 1/2/4 as a stacking trunk on stack unit 1. 

device# configure terminal
device(config)# stack unit 1
device(config-unit-1)# stack-trunk ethernet 1/2/3 to 1/2/4
