Displaying Multi-trunk Stacking Configuration

When the multi-stack trunk command is used to create a trunk, the configuration is saved as stack trunk ports, and the running configuration provides the stack trunk details on both ends under the heading stack unit <unit> configuration.

ICX8200-24P Router# configure terminal
ICX8200-24P Router(config)# stack unit 1
ICX8200-24P Router(config-unit-1)# multi-stack-trunk ethernet 1/2/1 to 1/2/4 and ethernet 2/2/1 to 2/2/4
stack-trunk ethernet 2/2/1 to 2/2/4 replaces stack-trunk ethernet 2/2/1 to 2/2/2 and stack-trunk ethernet 2/2/3 to 2/2/4
stack-trunk ethernet 1/2/1 to 1/2/4 replaces stack-trunk ethernet 1/2/1 to 1/2/2 and stack-trunk ethernet 1/2/3 to 1/2/4
ICX8200-24P Router(config-unit-1)# exit

The preceding example enlarges the two-port trunk ring to a four-port linear-topology trunk.

Use the show running-config command to display the related configuration under stack-trunk and stack-port. The show running-config command displays the following configuration for the previous example.

ICX8200-24P Router(config)# show running-config
