Creating ICX 7150 Stacking Trunks While the Link Is Down

Follow these steps to create a trunk while the link is down.
Note: Use the stack-port command while the link is down to remove stacking trunks and restore individual stacking ports.
  1. Enter global configuration mode. 
    ICX7150-24 Router(config)# configure terminal
  2. (Optional) Use the show stack command to check the stack topology and status. 
    ICX7150-24 Router(config)# show stack

     +---+        +---+

     +---+        +---+

    The example shows a two-unit stack with both units in the Ready state. The units are connected by a trunk through stack ports 1/3/1 and 2/3/1.
  3. Enter stack unit configuration mode on the active controller. 
    ICX7150-24 Router(config)# stack unit 1
ICX7150-24 Router(config-unit-1)#
  4. Enter the stack-trunk command followed by the range of ports to include in the trunk. 
    ICX7150-24 Router(config-unit-1)# stack-trunk ethernet 1/3/3 to 1/3/4
    The example creates a two-port stacking trunk containing ports 1/3/3 and 1/3/4.
  5. Create a stacking trunk for the same number of ports at the other end of the planned connection if the trunk has not been created. 
    ICX7150-24 Router(config-unit-1)# stack-trunk ethernet 2/3/3 to 2/3/4
    The example creates a stacking trunk from ports 2/3/3 and 2/3/4.
  6. (Optional) Enter the show running-config command to check the configuration. 
    ICX7150-24 Router(config-unit-1)# show running-config

    The example shows the stack with the existing trunk (1/3/1 to 1/3/2 connected to 2/3/1 to 2/3/2) and the trunk added on stack unit 1 and stack unit 2. To create a ring topology, the new trunk on the two stack units could be connected physically.

The following example creates a trunk on stack unit 1 while the link is down. 

ICX7150-24 Router(config)# configure terminal
ICX7150-24 Router(config)# show stack
