Adding new switch to IRF-stack

[kai_c_h]

Hello community,

I want to add a switch to an existing IRF stack [currently 4 devices]. This is the config I applied to the new switch:

system-view
    irf member 1 renumber 5
    y
    save f
    quit
    reboot
    y
    -STOP----- (after reboot)
    system-view
    interface range  Ten-GigabitEthernet 5/0/49 to Ten-GigabitEthernet 5/0/50
        shutdown
        quit
    irf-port 5/1
        port group interface Ten-GigabitEthernet 5/0/49
        quit
    irf-port 5/2
        port group interface Ten-GigabitEthernet 5/0/50
        quit
    interface range  Ten-GigabitEthernet 5/0/49 to Ten-GigabitEthernet 5/0/50
        undo shutdown
        quit
    save f
    irf-port-configuration active
    save f 
    (The device reboots now automatically)

After that, I added the switch to the stack, powered it up and connected the IRF cables appropiately.
The new switch remained in IRF state "Loading" for over half an hour. That seemed a bit too long for me.

What I didn't do was to make sure it has the same firmware version as the exisiting stack. Is it necessary?

I then tried to install the firmware to the new switch but failed to establish a connection to my computer using TFTP. Unfortunately I didn't do any firmware updates before using TFTP. I might do something wrong, is there some guide? I followed this example: https://www.youtube.com/watch?v=3ckpOclYvrs
But I cannot establish a connection.

Thanks in advance for any help!

Solved it myself: I updated the firmware, then it worked. Company devices had ports disabled, that's why TFTP didn't work...

Hi Kai!

All members of the IRF need to run the same code version and must be the same model family.  It's always best to upgrdae the firmware first and then add it to the IRF.  Comware will then merge any config and send it to the new member automatically.
