2930F switch and VSF with SPF cables

Hi,

 

I try to connect 2 switch 2930F whit SPF cables in VSF mode.

 

My câbles are HPE JH694A

My config :

First switch :

vsf
   enable domain 3
   member 1
      type "JL255A" mac-address 089734-9a9900
      priority 150
      link 1 1/25
      link 1 name "I-Link1_1"
      link 2 1/26
      link 2 name "I-Link1_2"
      exit
   port-speed 10g
   exit

Second switch

vsf
   enable domain 3
   member 2
      type "JL255A" mac-address 089734-9a4a00
      priority 128
      link 1 2/25
      link 1 name "I-Link2_1"
      link 2 2/26
      link 2 name "I-Link2_2"
      exit
   port-speed 10g
   exit

Ports 1/25, 1/26, 2/25 and 2/26 stay fixed orange.

I have allready activate

allow-unsupported-transceiver

When I check I have :

# show interface transceiver detail

  1  089734-9a9900     Aruba JL255A 2930F-24G-PoE+-4SFP+ ... 150 Commander

 

Does anyone know how to solve it ?

 

Thanks

Re: 2930F switch and VSF with SPF cables

AFAIK VSF doesn't form when unsupported Transceivers or DACs are used for VSF Link(s).

 

Aruba 2930F supports these two DAC cables:

 

  • Aruba 10G SFP+ to SFP+ 1 m Direct Attach Copper Cable

    J9281D

  • Aruba 10G SFP+ to SFP+ 3 m Direct Attach Copper Cable J9283D

Hardware revision B (J9281B and J9283B) should be supported too.

 

So you can eventually try to use unsupported SFP/SFP+ Transceivers or DACs but not to create VSF Link(s).

 

I suspect the HPE JH694A is the SKU of a old DAC cable unsupported on Aruba 2930F (at least to form VSF Link(s)).

Ok,

 

The stranger thing is that VSF has worked on my desk.

 

I put everything in my rack, nothing work.

 

I remove vsf configuration and configure it again, I plug câbles, ports goes green, the slave switch reboot but after the reboot vsf doesn't work and ports stay orange.

With exactly the same hardware and software configurations?

Yes, exactly the same configuration and hardware (maybe spf cables were interchanged, it's the only thing that can have change).

My IMC discover it correctly when VSF worked on my desk :

Did you find the solution?

Re: 2930F switch and VSF with SPF cables

I have posted a process to use unsupported third-party transceivers here:

VSF with non-standard transceivers

 

It should help you plan a solution. Only supported transceivers are recommended in general, but especially for VSF links.
