    Greetings!

     

    We're kicking off 2020 by releasing our latest best practices guide — this time, we're covering VSF deployment and maintenance on the Aruba CX 6300 switch family. Deploy, maintain, and troubleshoot 6300 VSF stacks using either the Aruba CX mobile app or switch CLI.

     

    As always, feel free to provide feedback or suggestions in this thread!

    Should it be possible to stack switches with copper cables? At least the mobile app doesn't seem to recognize other member if I use 1Gbps ethernet from ports 23 -> 24 and 24 -> 23.

     

    Asking as I haven't received the proper DAC cables yet but would like to try VSF

    Only the SFP56 ports can be used for VSF links.

    Is there a 'unsupported-transceiver' command for 6300F :)?

    Hi Matt

     

    Am I reading it right that these new products do not have a method for an 'in service' or fast software upgrade when the switches are stacked in pair..  or am I missing something in the documentation/oversight in the documentation?

     

    Thanks

    Yes no ISSU or fast software upgrade on 6300

    My experience with 6300M VSF:

    - Configure everything either manually or using the Mobile App

    - Everything is working

    - Remove power from the switches.

    - Connect the switches to power

    - Wait

    - Only master works; all others get stuck on boot.

    no need for TAC.

    Cli:

    write memory

    App:

    Copy running to startup

     

    Tried both methods.

    And as told, Master does have configuration. Hostname is set, vsf links are set, etc.

    It's only the Slaves that do not keep the config. They get stuck on boot. If I CTRL+C the boot proceeds, but the switch config is empy.

    Only way to recover the switches is to wipe to factory defaults (erase zeroise).

    ok, thank you for such clarification.

    Then, indeed, a case must be opened.

    You need to do a "copy running startup" before power-off.

    This  is achieved on the CX mobile app here attached.

    Yes, the configuration is saved.

    Master config is intact after power-down / power-up.

    Only secondary and slaves get stuck.

    How did you save configuration before power-off ?

    Has any progress been made with the app for VSF?  10.05.0030 and still not able to stack two new switches, using the SFP56 DAC interconnects.  As Ricardo said nearly a year ago, the configuration appears to work up until commit time.  Then the member switch times out and a failure message is presented.

    After manually rebooting (power off/on), the secondary joins, but attempting to login using its console puts the admin in "member02" low-level console, rather than backup.  Rebooting with the DAC link disconnected results in the secondary not being able to complete the boot.

    Stacking at the CLI seems to work as intended.

    I've seen the same behaviour using the app with the 6200, and have configured them at the CLI successfully.

    Feels like a TAC call coming on...

    Solved - needed to define a secondary/standby.  Did that and things worked well.  Missed the checkbox in the app.  Can do this from the app by editing the member and checking the box, or using the CLI to declare which member is the standby member.

    do you have commit the config ? (may be better to open a new topic) and do you have configure a secondary switch ?

    Hi,

     

    It was confirmed on this thread that the copper ports on the 6300 devices cannot be used to form the VSF link as the SFP56 ports are the only ones supported for such feature, however I would like to know if this restriction applies to the 6300M JL658A  (use any of the SFP+ ports for VSF link).

    Also, is it still recommended to have a "chain" topology in a 2 member VSF (I can inherit it from the guide "If the stack will contain more than two members, configure VSF link 2 as well:", however it is not specifically indicated).

     

    Thanks.

    What is the best way to form a two switch stack of CX6300?

     

    This works:

    vsf member 1

    link 1 1/1/49-1/1/50

    vsf member 2

    link 1 1/149-1/1/50

     

    This doesn't work:

    vsf member 1

    link 1 1/1/49

    link 2 1/1/50

    vsf member 2

    link 1 1/1/50

    link 2 1/1/49

     

    We would like to use the second form for two reasons, it makes it easier to add additional switches to the stack. Also, the SHOW VSF TOPO command will show all the interconnects.

     

    How do we get the second form of stacking working for two switches?

    We are using the latest firmware (10.04.3011) on the switches.

     

    Thanks

    Hi, why do you think it will be easier to add additional switches to a VSF Stack made of a pair connected with two VSF Links (remember that the rule about the amount of VSF Links is: one VSF Link if you're dealing with a 2 members stack, two VSF Links if you're dealing with more than 2 members stack).

     

    With a two VSF Members stack the correct way to go is (as example):

     

    vsf member 1
    link 1 1/1/49-1/1/50
    vsf member 2
    link 1 1/1/49-1/1/50

     

    because you're dealing with a chain (a single link chain where the single logical VSF Link - link 1 - is made of two physical interfaces).

    Please refer to the ArubaOS-CX Virtual Switching Framework (VSF) Guide for Aruba CX 6200, 6300 Switch Series available here and also to the VSF Best Practices Guide for the Aruba CX 6300 Switch Series available here.

     

    AFAIK the vsf show topology command (try also show vsf link) will show the interconnects correctly when you're dealing with just a single VSF Link too (2 members VSF Stack).

    First, coming from the Cisco world, I have implemented a ring topology with just two switches for a couple of decades. It was not apparent that I couldn't do this with the CX line. 

     

    Due to this requirement, when it comes to adding the third switch, I must reconfigure the first two switches by disabling a port and removing it from link 1 on each switch. Then add the port to link 2 and enable the port on each switch. It's not hard but, it is a number of steps.

     

    If a ring topology were supported with two switches, I'd merely have to configure two links on the new (third switch) and insert it in the ring. 

     

    Since I am new to the Aruba line, please correct me where I am mistaken on this topic.

     

    Best,

     

    Tony
