Wired Intelligent Edge

I followed the below linked guide to stack 3 identical 2930f switched together in VSF configuration but it is not working and need some assistance on what I am doing wrong. VSF link port light are solid orange. Consoling to each switch notes all links are down and each is a commander.

Any pointers would be a great help

Hi David, you configured the global VSF parameter "port-speed 1G" to impose 1Gbps VSF links but, if I'm not mistaken, VSF Links ports 49 and 50 represents SFP+ capable slots (apart from supporting both SFP and SFP+ Transceivers), given that this note could be relevant:

"In the case of transceiver ports, the speed is determined by the bay type. An SFP+ bay, if configured, will set port speed to 10G. If an SFP transceiver is inserted into the bay, it will not link up and be in error state."

I believe that the above note means that even with an SFP Transceiver inserted (thus 1G capable, at maximum) into the the 10GbE SFP+ port 49-52, that port - from the point of view of VSF Link - will be seen as 10G capable no matter the port-speed 1G setting you configured.

Do a test, if you can, and change to only-1G capable ports like copper ports 47 and 48 (as example) instead of ports 49 and 50.

Another thing to check is the connectivity: verify that the VSF Member 1 Link 1 port is connected to VSF Member 2 Link 2 port and VSF Member 2 Link 1 port is connected to VSF Member 3 Link 2 port...and so on...up to closing the entire loop into VSF Member 1 again (VSF Member 3 Link 1 port to VSF Member 1 Link 2 port).

HI,

Changing the ports to 47/48 on each witch and using patch cables seems to work fine.

Hard to believe that these ports can not be utilized and 6 ports need to be wasted to stack them together.

Thanks for the info.

Great!

"Hard to believe that these ports can not be utilized and 6 ports need to be wasted to stack them together."

Can't you use six (three pairs) supported 10G DACs so you can finally use ports on 49-52 range at their maximum potential (and eventually set VSF global parameter port-speed to 10G just to match the SFP+ port type)?

Just curious...if you were already trying with 49 and 50 and it didn't work...it means you tried with some SFP Transceivers instead of SFP+ ones, correct? at that point a rising question would be: why to waste "fast" SFP+ ports with "slow" SFP Transceivers - we imply that they were readily available, isn't it? - and use those SFP ones to form VSF Links which, generally, require instead higher speeds (as a best deployment practice)?

They don't fall into this bracket and other transceivers used are compatibles for linking to other switching on the business site and work with no problems.

I have logged a call to HP support and waiting for an engineer to call back, hopefully they can resolve the issue or advise what's wrong.

Hi David,

I set up a VSF with two 5400 Series switch recently.

For 2930 there is this guide - maybe it´s useful for you:

Hi David, you configured the global VSF parameter "port-speed 1G" to impose 1Gbps VSF links but, if I'm not mistaken, VSF Links ports 49 and 50 represents SFP+ capable slots (apart from supporting both SFP and SFP+ Transceivers), given that this note could be relevant:

"In the case of transceiver ports, the speed is determined by the bay type. An SFP+ bay, if configured, will set port speed to 10G. If an SFP transceiver is inserted into the bay, it will not link up and be in error state."

I believe that the above note means that even with an SFP Transceiver inserted (thus 1G capable, at maximum) into the the 10GbE SFP+ port 49-52, that port - from the point of view of VSF Link - will be seen as 10G capable no matter the port-speed 1G setting you configured.

Do a test, if you can, and change to only-1G capable ports like copper ports 47 and 48 (as example) instead of ports 49 and 50.

Another thing to check is the connectivity: verify that the VSF Member 1 Link 1 port is connected to VSF Member 2 Link 2 port and VSF Member 2 Link 1 port is connected to VSF Member 3 Link 2 port...and so on...up to closing the entire loop into VSF Member 1 again (VSF Member 3 Link 1 port to VSF Member 1 Link 2 port).
