Configuring an ICX 6430 and ICX 6450 IronStack
Error- Primary trunk port 1/2/3 is not UP; removing the trunk might break the
stack
To upgrade to a double port trunk configuration, enter the multi-trunk command under the stack
unit configuration level. Enter the following command.
Brocade(config)#stack unit 1
Brocade(config-unit-1)# multi-trunk 1/2/3 to 1/2/4 and 2/2/1 to 2/2/2
Brocade(config-unit-1)#stack unit 2
Brocade(config-unit-2)# multi-trunk 2/2/3 to 2/2/4 and 3/2/1 to 3/2/2
Syntax: [no] multi-trunk
Use the no form of the command to disable the configuration of the two connected stack trunk
ports, and convert the secondary stack ports to data ports.
Displaying multi-trunked stacking configuration
When upgrading to a double port trunk configuration using the multi-trunk command, the
configuration is not saved in the running or start-up configuration. Instead, the configuration for the
multi-trunk command is saved as stack-trunk ports. Use the show stack command to display the
configuration for multi-trunked stacking ports. For example, the following command is entered.
Brocade (config-unit-1)# multi-trunk 1/2/3 to 1/2/4 and 2/2/1 to 2/2/2
The running or start-up configuration displays the following configuration for the show stack
command.
Syntax: show stack
Periodic background stack diagnosis
for ICX 6430 and ICX 6450 devices
After a stack forms, the system periodically probes the topology to check the connections between
units of this stack. It can detect the following errors. The purposes are to detect user's connection
problem and hardware failures. Error messages are printed about every 10 minutes. If there is no
printout, there is no problem. This diagnosis runs in the background.
Manually triggering stack diagnosis
You can manually trigger the diagnosis using the show stack connection command.
