Configuring an ICX 7650 Trunk Manually on a Non-production System

Stacking trunks can be configured on ICX 7650 devices operating in 40-Gbps stacking mode.

The stack interactive-setup process includes the option to form trunks when multiple links are possible. You may also opt to configure a trunk manually.

Follow these steps to create a trunk manually on an ICX 7650 stack that is not live.

Note: Stacking trunks can be configured only when the rear module is operating in 40-Gbps stacking mode. Refer to ICX 7650 rear-module options for more information.
Note: Trunk configuration may be removed when you change stacking speeds.
  1. (Optional) Verify that stacking is enabled and that the rear module is configured in 40-Gbps stacking mode.

Current stack management MAC is 609c.9f52.5eb9
Rear-module: config = oper = stack-40g
Stack ports are operating at 40G.
    The example shows that the unit is operating in 40-Gbps stacking mode, but stacking is not enabled. No stacking links are configured to other units.
  2. Enter stack unit configuration mode to configure trunks. 
    ICX7650-48P Router# configure terminal
ICX7650-48P Router(config)# stack unit 1
ICX7650-48P Router(config-unit-1)#
ICX7650-48P Router(config-unit-1)# stack-trunk ethernet 1/3/1 to 1/3/2
ICX7650-48P Router(config-unit-1)# stack-trunk ethernet 1/3/3 to 1/3/4
ICX7650-48P Router(config-unit-1)# exit
    The example configures two stacking trunks on stack unit 1.
  3. If necessary, enable stacking on the device. 
    ICX7650-48P Router# configure terminal
ICX7650-48P Router(config)# stack enable
Enable stacking. This unit actively participates in stacking
  4. Enter the write memory command to save the trunk configuration. 
    ICX7650-48P Router(config-unit-1)# end
ICX7650-48P Router# write memory
  5. Repeat the previous steps to enable stacking and configure trunks as needed on all units in the stack.
    Note: This step is configured on each separate unit. As shown in the example, each standalone unit identifies itself as "stack unit 1" until it joins a stack. 
    ICX7650-48P Router# configure terminal
ICX7650-48P Router(config)# stack unit 1
ICX7650-48P Router(config-unit-1)# stack-trunk ethernet 1/3/1 to 1/3/2
ICX7650-48P Router(config-unit-1)# exit
ICX7650-48P Router(config)# stack enable
    The example shows a standalone unit being enabled for stacking and configured with a single stacking trunk.
  6. Wait for the election to take place.
    The second unit is reloaded as a stack member.
  7. (Optional) Confirm that the stack has formed based on the stacking links configured.
