[AusNOG] Running out of VLANs

[Michael Andreas Schipp]

Hi James,

If you need to replace kit with higher end Cisco, Brocade, Arista whatever, suggest you step back and look at why you are needing so many VLANs and not just look at the vendor newer tin but if new tech can also help e.g. QinQ/TRILL/SPB and the like.

After you work out what tech to use (and this may end up being that more of what you are already doing) then take a look at the vendors with port density, speeds and feeds (and costs of HW and support).

Thank you,

Subject: [AusNOG] Running out of VLANs

Hi Noggers,

What are people doing about hitting switch VLAN limits? We terminate a lot of Ethernet services from several carriers. Our Cisco switch gear is great but limited to 128 spanning tree VLAN sessions and 1,000 VLANs.

We've long since passed the 128 per-VLAN spanning tree limit. We're now getting closing in on 1,000 VLANs.

I'm sure there are service providers on list who are much larger than we are and have solved this problem.

Would love to hear thoughts on the best approach.

Just to give a bit more detail - we aggregate all our upstream carrier circuits on the Cisco switch then trunk the customer VLANs to the appropriate router for termination.
