Do the new Aerohive switches support wire speed ACLs?

Are packets ever copied to the CPU to be filtered, if so, under what circumstances?

Do the new Aerohive switches support any dynamic routing protocols such as RIP, OSPF and PIM?

If not today, are any of these planned to be offered in the future?

Do the new Aerohive switches support sFlow?

If not today, is the hardware necessary to support this present? And, if so, are there plans to offer this in the future?

Any news on this? Has this been implemented or does anyone if this will be supported in the future? I'd personally much prefer unsampled sflow.

Do the new Aerohive switches support wire speed TCAM-based L3 routing for both IPv4 and IPv6?

Or are packets destined to be routed copied to the CPU?

If not yet for IPv6, is the hardware present to support this in the future?

Do the new Aerohive switches support MSTP? The documentation only claims STP and RSTP support.

I'm curious to know if the new Aerohive switches can be stacked together physically using the SFP+ ports? Or is the stacking virtual and purely from a management perspective?

I'm curious to know if the new Aerohive switches support 802.1X-2010 (EAPOL v3) and 802.1AE (MACsec)? If not today, does the hardware support it?

The documentation states 802.1X support, which is ambiguous as there have been three versions of the standard 802.1X-2001, 802.1X-2004 and 802.1X-2010.

Nice job going through the data sheets and coming up with a nice list of feature requests!

However, as you probably know, we can't discuss roadmap on the Community but you shouldn't be surprised as most of those features start showing up.

Feel free to send me your contact info via community@aerohive.com so I can reach you directly and we can talk about it.

Dear Daniel,

Thanks for responding. Please do not feel that you have to reply to this, but it was not at all meant as a list of feature requests, rather genuine questions as I am trying to determine suitability for an educational site that is due to replace its switching.

1) I am curious how the ACLs are implemented in the design of Aerohive's switching. This will usually dictate if you get wire speed performance or not when ACLs are used. This has implications as to the suitability of a switching product to particular use cases where wire speed performance is desirable or required.

2) I am curious what dynamic routing protocols are offered, if any, at the moment. These are very often required in Enterprise use cases so I would find it very surprising for such a class of switch to not support them at inception. I wondered if it was an oversight in the initial documentation, therefore, and that some were actually offered. From your answer, I now suspect not at the moment, however. That is fine and good. I did not ask this, but I would also expect VRRP support in such a class of switching.

3) I was curious if the switching chips used support sFlow, even if Aerohive have not yet written or offer full software for it yet. This would show the potential scope for future development here as hardware support is required. (You can, of course, determine this by opening a switch to see what chips are inside it...)

4) I am curious if IP routing would be implemented by TCAM in hardware or would be instead handled by a CPU, this will usually dictate if you get wire speed performance or not when they are used. This has implications as to the suitability of the product to particular use cases where wire speed performance is desirable or required.

5) I was curious if it was just STP and RSTP that were implemented or, instead, an oversight in the documentation. MSTP is a 2002 standard and is widely implemented competitive products, and is often used in the Enterprise. This has implications as to the suitability of the product to particular use cases. I now understand that this feature is not yet available, thanks!

6) I am curious how the stacking works (virtual and/or physical?) as the documentation that I have seen is not, to me, clear in this area. (Questions such as do you get distributed link aggregation, distributed routing, distributed configuration arise.) This has implications as to the suitability of the product to particular use cases.

7) I am curious what version of 802.1X is implemented as the data sheet is ambiguous and does not state this. This has implications as to the suitability of the product to particular use cases.

With regards,

Nick

Dear Nick,
I'm sorry but I didn't know that external emails are being blocked... we are working on it!

I’m not trying to discount or ignore your questions, they are actually pretty good ones, but because they are clearly biased towards the “If not today, are any of these planned to be offered in the future?” which I can’t address in this Forum, I’d rather explore directly with you whether they are suitable for that site.

And I believe we’ve found a workaround to get your email so hopefully we’ll talk soon.

That's a very fair point, they are inherently biased that way.

The campus in question presently has many stacked 3Com 5500/HP E5500 switches (Fast Ethernet) at the edge and 3Com 5500G/HP E5500G switches (Gigabit) at the core and for distribution. It is now due for upgrade/replacement.

I was, and am, attempting to determine the potential and suitability of Aerohive's new switches to be used at the edge of their network and, yes, to also get a sense of where things are going.

The incumbent switching is relatively feature rich and they do make extensive use of the features available, but they are now many years old and out of all support except for swap out of failed hardware. Upgrade/replacement is ballpark budgeted for and is on the horizon.

If not suitable today, it may well be worth holding off replacing the edge there now if Aerohive's offering is to evolve quickly over the next year or two, it looks really promising!

It would be fantastic, if viable, to have the edge handled completely by one management system that is so well integrated!

Fantastic, and got your address!

I think this is an even better plan: we'll get a local Systems Engineer to help you with our current capabilities, and I'll make myself available for roadmap information.
