VSF Stacking on 2930f

[cdelarosa]

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.

Yes, you can stack up to 4 units with any model of the family of 2930F

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,

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

[Pepe Echeandia]

Yes, VRRP is supported.

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

[Pepe Echeandia]

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