Can i do VSF stacking between a 2930F of 24P POE with a 2930F of 48P Poe???

Cheers

Hi, 

Yes, you can make a VSF stack using different 2930f models.

http://h20566.www2.hpe.com/hpsc/doc/public/display?docId=c05365316 page 605

The VSF feature allows the user to form a stack of up to four devices of any SKU, 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.

Hello,

It-is possible to setup a stacking with four 2930 F with Copper 1 Gb and fiber 10 Gb like this ? Two 2930F interconnected with two Copper 1 Gb in a room . Two other  2930F interconnected with two Copper 1 Gb in a second room and the two rooms interconnected with fibre 10 Gb.

                    (one OM4 10 G)

2930F --------------------------------2930F

  I |                                                | |

  I |  (two  Copper 1 gb)                 | |  ( two  Copper 1 gb)

  | |                                                 | |

2930F --------------------------------2930F

                 (one   OM4 10 Gb)

Thanks a lot,

Hervé

Hi, sadly, no ... but its a good idea!

At least you can do link aggregation between the rooms.

Look at page 653 from here

VSF restrictions

• VSF is mutually exclusive with distributed trunking, mesh, and Q-in-Q.

• VSF port restrictions:

    ◦ Must be 10Gbps/1Gbps.

    ◦ A VSF link can only comprise ports with the same speed; either all 10G or all 1G. A VSF port’s speed which does not match with the global port speed, will be in a down state. The command show vsf link detail will display an error message.

    ◦ Maximum eight ports can be configured on one VSF link.

    ◦ VSF ports must be directly connected and there should be no transit devices between members.

• In a VSF virtual chassis, flow-control is not supported between ports on different chassis across VSF links.

• A VSF stack downgrade is not allowed if we try to downgrade a 2930 VSF stack to a 16.02 image.

Ok..

Or i replace  copper by fiber and it s ok but i have note fiber port availbale.

And if i do link aggregation between the rooms, i have two VSF stacking, one  VSF in each room. It is possible to do VRRP between these VSF ?

Thanks a lot,

Hervé

Yes, VRRP is supported.

Routing Manual page 241

ok thanks a lot.

hi sorry, does this mean that 1Gbps or 10Gbps is supported for VSF stack for 2930F series? 
1Gbps is workable? I am looking into 2 units of 2930F 24G SFP to perform VSF stack. 

Please advice, thank you

Yes, you can configure VSF using 1G links over 2930F.

yes, i've tested and it works. so is possible. thanks

Plese tell me how...
i want to do the same. two 2930F just with SFP (not SFP+) and VSF Stacking.

Best

Can you please let me know if i have THREE 2930F switches and i want to stack them(VSF) so what commands should i run on each switch to put all of them in stack. Kindly share the step by step commands.

Cheers

I just recently did a setup with 3 switches and finally got them to stack correctly.   Here is the post that helped me - Configure Virtual Switching Framework (VSF) the easy way

basically you configure the port that you will use as the uplink to a Link port (vsf member # link # <port>) and then connect the new switch to that port  while the new switch is off.  Then power it on and it should be detected and setup in the VSF.

When you are ready to link them into a loop, you can then add a second Link port with a different number (1-2) and then connect the cables.  To get the loop to detect it MAY take a reboot.
