How to stack 2930F?

[Nick IT]

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.

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.

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?

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?

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.

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

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

Thanks & Regards,

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
