Hello everyone,

I have an SPBM cloud using VSP7024 switches (14 in 4 locations). On this we run our production network and services. We also manage the network for a small business location where all buildings have 4 or 8 fiber links and we use this to provide internet and connectivity services to the companies at these locations.

One of the companies at this location has several buildings and they want to upgrade their network to 10G. They have bought some new switches and they asked us if it would be a problem if they would start using TRILL to connect all the switches at their different locations together.

I have a few questions, because I'm not completely familiar with the inner workings of TRILL.

- Do I need to provide transparant I-SID's to connect their locations, or do they need VLAN's?

- Does TRILL interfere with my SPBM cloud? As far as I understood, TRILL also uses IS-IS but with a layer 3 IP network instead of a Layer 2 ethernet network.

- There are also some VLAN's I need to inject into their network. At the moment this is very simple because I manage the VLAN's they use between the buildings, when I need to create transparent I-SID's between the buildings, how do I inject the VLAN's they need? I was thinking of creating a multi-port I-SID to connect all their buildings together and create one extra port where I inject the VLAN's they need from me. Does this work?

- What other things do I need to be aware of?

Has anyone done something like this before?

I didn't see this when it came in, so it's a little stale. I also can't answer the question exactly. But I can tell you about an experience I had.

We use an RFS4000 with around 100APs. Our APs are set to bridge -- not tunnel -- traffic, meaning the RFS4000 itself is not involved in handling wireless traffic; it only manages the APs. We had an issue on the controller where the temperature sensor failed. The hardware was otherwise provably good, but the OS refused to boot, because it thought the system was overheated. We didn't have a spare at the time, and it took about 4 days to acquire and provision a replacement. Wireless service during this time was... not good. It was surprisingly very bad. This is in spite of using a controller that should never process any traffic on it's own.

The point is you almost certainly do need to keep the licenses available for all of your APs. Removing the licenses will limit the controller from managing all of them, and the controllers ability to manage the APs absolutely does make a HUGE difference.

Your information is very interesting. It makes me want to participate in this conversation.

I think what you are talking about is the information I want, which I want to be involved with.

I am trying to get EAP-TLS authentication working on my WLAN 9100 system through our Ignition server.

The error message in the Ignition log is "RADIUS request timed out (client failed to respond).

The environment works fine using pre-shared keys and/or RADIUS with username/passwords, but as soon as I tried to use EAP-TLS I get the above error. I've tried mobile clients (iOS and Android) and Windows 7 clients as well with the same error.

My APs are running AOS 8.1.3 and the Ignition Server is 9.2.4

I have loaded my CA and sub-CA certificates as protocol root certificates.

Has anyone seen this issue before or have insight into what the issue could be?

I guess this isn't possible.  ;D
could you please let me know what is the difference between level 1 and level 2 mint links and when AP will form level 1&2 mint links with Controller..

Level 1 Mint is used for Local Controller, and Level 2 Mint is used for Centralized controller.
Let me give a ex: If u have branch office and head office Centralized controller will be placed in head office and in branch office's u will keep only Local controller to control the AP's which is belongs to Your branch. and in few branch offices u dont have ;local controller at that time you have to use level to Mint for those to access from centralized Controller, like RFS6000, RFS7000 are used for local Controller and VX9000 will be used for Centralised

Theoretical build idea.. Just wondering if anyone has ran a similar setup successfully..

Active-Active cluster, tunnel mode SSIDs which get natted to address(s) on the controller.

Also adding port channels for additional bandwidth along with VRRP for the addresses participating in NAT.

XMC has currently version and was able since to backup and restore the config of ERS and VSP devices. I personally have never tested the bulk config changes function.
All needed function of COM Plus / EFO will be available in XMC in upcoming version 8.2, estimated July/August 2018.
Let's see ;)

Has anyone any experience using Extreme Management Centre with Avaya ERS and VSP switches using it for bulk config changes and backup and restoring config?

We saw an early incarnation but it was very limited functionality with Avaya ERS and VSP hardware!!

Has it now matured and become a useful tool, better than COM;-)
