    Posted Sep 18, 2018 05:24 PM
    I have 1 aruba 2930F 48G 4SFP+, 2 24G POE+ 4SFP+ switches. How should I stack them?
     
    Can I stack all 3? or just 2 24 poe+?

    You can stack all 3 up to an 8 member stack if running 16.06 code.

    Does the number of ports on the switch has to match to stack or doesn't matter? like we can stack 1 48port + 24port as long as they are on 16.06?

    No, it doesn't...you can mix. The main requirement is to use the same speed on ports part of any VSF Link(s) on any VSF Member of the same VSF Domain.

    Yes, you can.

    Also can you list detailed steps to stack 1 48G ports as commander and 2 24G ports as members? I have never done this and really appreciate your help.

     

    I have 10G DAC cables. What is the recommended stacking, switch1 10G sfp+ port1 to switch2 10G sfp+ port1 or port2?

    Read the VSF Chapter on the Aruba 2930F Management and Configuration Guide for ArubaOS-Switch 16.06 (August, 2018) available here.

    To explicitly designate a switch as the preferred VSF stack commander, first enable VSF on that switch (do not connect any VSF links yet!):

     

    switch(config)# vsf enable domain 1337

    This will reboot the switch. Once the switch has rebooted with VSF enabled, it should be member 1 as well as the de facto commander. Use the following command to set its priority to the maximum value:

     

    switch(config)# vsf member 1 priority 255

    This will ensure that this member will be selected as commander during any stack election (e.g., the stack reboots after a software upgrade or after a power outage). You can then add any additional stack members using the methods listed in the document linked by parnassus above.

    The VSF feature allows the user to form a stack of up to eight devices of any SKU of 2930F, including mixing the SKUs in a single stack. The switches in these stacks are interconnected using standard Ethernet connections. These interconnections between member switches are called VSF links. Please feel free refer chapter 32

     

    http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-a00038765en_us-2.pdf

     

    sample configuration:

     

    Switch 1:

     vsf member 1 link 1 25

    vsf member 1 link 1 26

    vsf member 1 priority 160

    vsf enable domain 5

     

    Switch 2:

    Vsf member 2 link 1 25

    vsf member 2 link 1 26

    vsf member 2 priority 150

    vsf enable domain 5

     

    Switch 3:

    Vsf member 3 link 1 25

    vsf member 3 link 1 26

    vsf member 3 priority 150

    vsf enable domain 5

    I did manual vsf as per pdf guide but when I do show vsf it show topology as chain but I have connected the cables in ring. Why is that? sw1 to sw2, sw2 to sw3 and sw3 to sw1

    All three VSF members should have two VSF links configured — one link to each of the two member it is connected to. Run show vsf link and make sure all links are up and that the peers are displayed as expected.

    link 2 is down for member 2 and link 1 is down for member 3

    what am I doing wrong?

     

    sw1 - port49 to sw2 - port27

    sw2 - port25 to sw3 - port27

    sw3 - port25 - sw1 - port51

     

    Here is my config:

    enable domain 5472
    member 1
    type "JL254A" mac-address aaaaaa-aaaaaaaaa
    priority 200
    link 1 1/49
    link 1 name "I-Link1_1"
    link 2 1/51
    link 2 name "I-Link1_2"
    exit
    member 2
    type "JL255A" mac-address bbbbbb-bbbbbbbbb
    priority 150
    link 1 2/25,2/27
    link 1 name "I-Link2_1"
    link 2 name "I-Link2_2"
    exit
    member 3
    type "JL255A" mac-address bbbbbb-bbbbbbb
    priority 100
    link 1 3/27
    link 1 name "I-Link3_1"
    link 2 3/25
    link 2 name "I-Link3_2"
    exit

    Ensure that the cable used for the link between members 2 and 3 is connected properly, and that the interfaces used for the VSF link are enabled on both ends. If the link still doesn't come up, try swapping with a known-good cable and see if the link comes up.

     

    EDIT:  I noticed that your configuration has two ports assigned to Link 1 on Member 2, and no port assigned to Link 2. Move port 2/25 or 2/27 to Link 2, and you should be good to go.

    I tried to move 2/27 to link 2 but says "Removing of binding between physical ports and VSF link is not allowed since it
    would result in a stack split."

     

    How should I do that?

    Disable the port you intend to move to Link 2 (e.g., 2/27), then swap the VSF link configuration:

     

    switch(config)# interface 2/27 disable
    Disabling VSF port will result in stack split. 
    
    Continue (y/n)? y
    switch(config)# no vsf member 2 link 1 2/27
    switch(config)# vsf member 2 link 2 2/27
    switch(config)# interface 2/27 enable

    When I did that sw2 became member and sw3 became standby.

     

    How should I swap them?

    You can force member 2 to assume the standby role by rebooting member 3, using this command:

     

    switch# boot vsf member 3

    Greetings!

     

    You can stack any members of the 2930F family using VSF, so long as they're all running the same software version and using the same speed ports for the inter-switch VSF links (either all 10G or all 1G). As mentioned by Justin, you can stack up to 8 switches as of the latest switch software release, 16.06.

    I have 2 stacked switches 2930F , and I'm trying to  create a new vlan, but I cant  access the commander and I cant find the IP of the commander i can only access the stand by. please help

    There is only "one" address, you cannot address the Commander & Standby individually.

    Make sure you have at least on SVI with IP address, your PC can reach,
    otherwise you must use the Console ports to address the stack.

    Sett the Standby to one number less (127) than the Commander to clarify who is who
