No More than one Uplink per Vnet?

[Nima Gh.]

The Reasons:
1. I need to have at least 5 ports and Prorcurve cannot handle FlexNIC partitioning!
2. I am using both LOMs and Mezzanine Ports. then for each mezzanine port do I need to obtain one or more extra procurve switch?
3. It seems that Flex-10 and Procurve are not stackable! are they?

Any comments?

"What I exactly want is to include a couple of Uplinks into the same VCNet and on the other hand"

I have told how to do this

" to put the other end of the cords DIRECTLY to 10G Ethernet Ports of an external server (and not switch). "

This can not be done, VC needs active device eg. switch to be connected.

Connecting directly from external system to a Flex10 module (i.e. with no intevening switch) would require a cross-over cable if it was possible at all.

I had a situation where an external server was connected directly to a port on a 1/10G VC Ethernet module, however it was connected with a crossover cable (VC module is NOT a switch). And it was connected to a port which was NOT part of an uplink set.

I dont know if there is such a thing as a 10G crossover cable! (maybe that's a stupid statement??)

Cross-over cables have not been required for "compliant" Ethernet since the days of 100BT. These days it is all sorted automagically.

As for mixing Flex-10 and 6120, yes, one can have Flex-10 and ProCurve 6120's in the same chassis. Things should still match in the horizontal direction.

"(VC module is NOT a switch)."

An unconfigured VC module will pass all traffic on it's internal facing ports to any connected external facing ports (and vice versa)... acting like a simple switch (a very simple switch), though there is no other functionality like on a reqular switch.

That would be "almost a hub" :)

[Nima Gh.]

I tried! But I cannot stack VC and Pass-thru!

[Nima Gh.]

and Procurve as well!

[rick jones]

"stack vc and pass thru" - what exactly do you mean by that?

Also, to have Flex-10 VC and other 10G Ethernet modules in the same chassis, where the "other" Ethernet modules are connected to Flex-10 capabable mezz cards you should be on the latest VC firmware - IIRC that is 3.10 right now. There was a bug in the older VC Flex-10 firmware where it would reach-out and touch all the Flex-10 capable 10 GbE NICs it saw, whether they were connected to a Flex-10 or not.

A New Case:

I want to share a 20Gbps traffic between a c3000 chassis and a c7000 chassis!
I need servers at both c3000 and c7000 to be in the same collision domain! Is it true to connect pair of uplinks (both @ same vnet) from c7000 to the pair of uplinks (both @ same vnet) @ c3000, to share this traffic??
