Hello all! I have a question regarding spanning tree, dhcp server and a doorbird intercom.
I'm trying to install a new Doorbird doorphone in my current setup: an ICX6450-24p with a multi vlan setting, the dhcp server is the switch itself for every subnet. I tried a lot of spanning tree options but I'm not able to get an IP from the dhcp server for the intercom (Doorbird doesn't have a manual ip option, go figure..). In this online page they state for example for Cisco equipment:

"Make sure to activate "PortFast" in your switch management and/or deactivate STP recognition. If this option is not set, our devices may not reconnect after a routine restart."

I also tried on a Cisco 3750 (global config: spanning-tree mode pvst) and on a Juniper EX3300 and i get an ip right away. To note that the Cisco environment uses a Windows dhcp server, but the Juniper was set up from scratch with internal dhcp server just for the test.

Does anyone know any type of config that should fix this issue that I have? What could be the difference between the 3 switch implementations?

Anyone run into this on an ICX6450 (or others)?

Code: 
stack: 008779b4 0171327c 016e9b34 017126f0 016e9d6c 0107cf00 0073bcac 013a2904 0136b7b4 0136e330 0136e9a4 00524594 00885e8c 019be3f8 019bea7c 019c08ac 019d7950 019d93f0 011d4508 007363a8 011da374 016d9d0c 0228f2ac 02fc7790
Error: I2C access failed for device 0x18, command -1071879421, I2C code = 0x1, SIM Code = 14, TWSI Sts = 0xf8
sil_kx_cpld_read: failed to do a cpld read for address 0x18, at offset 0x0
I'm getting this on console and it doesn't look good. The switch is definitely in sort of a bad shape since my SNMP exporter fails occassionally. I've also had an issue a few months back where I couldn't even run write mem. Only solution was to reboot.

Is the NVRAM/something else just toast?

Trying to decide between a 6450 and 7250. I do not need the 8x 10g ports, but I like that the 7250 is not EOS yet. Thought I'm not sure what that means at this point in its life. Are they still releasing new software? I think I've read most of this thread and a good deal of searching and I think there are 2 pros in the 6450 column. 1) little cheaper on ebay but not cheap enough to sway me and 2) the system seems to care less about fan rpms making it easier if I find the noise too loud.

I believe they both will work with the same console cable.

Is there anything else I'm missing? Maybe rest api? I need to google that still.

6450 will be quieter - 7250 have a specific droan. 6450 will use an older version of 080 code train where the 7250 will be newer version, but you still cannot run 9 or 10 code trains on any of them. The thing I hate about brocade is they have 2 gates for fan noise, level 1 or 2 - not like aristas where its a %. Outside of that some commands will be different between 6 and 7 due to the newer versions.

6450 will also use less power and be quieter as its got less fans.

Thank you for the reply. Still new to the icx world, it looks like.9.X has an API and the 7250 has a 9.x release, but at a glance it requires an account. Im guessing a support contract is needed too. Is that the issue or am I missing something.

All you need to do is register (Ruckus ICX 7250 Campus Switches | Products | Ruckus Wireless Support) and I do not think the 9.x release will run on that switch as the recommended version is 08.0.95n - I am fairly certain that the cpu cannot handle it.

Ok thanks! Any thoughts on a 2 fan vs 3 fan 7250-48p? I saw two on eBay and was surprised it didn't have 3 from my reading there and elsewhere.

OEM ICX7250-24P is 2 fans and ICX7250-48P is 3 - there is some discussions in this thread that you could unplug one of those fans if you are not using the entire the POE budget. The ICX7250 in my opinion runs hot, so I never did any of that.

The 48p variant comes with 3 fans from the factory - and should. It needs them.

You can make modifications to the fans, add one to the ASIC, etc, but it should have 3. It'll run too hot without.

That would make sense, but ah! I see my issue now. The listing says 48p but bottom label just says 48.

Fwiw, and please know I'm coming at this with only Google knowledge and not hands on experience with these switches. The docs all say 9.0. is supported on the 7250. I can't speak to feature parity though. I see a few folks mention it as well but not a lot.

you can try reflashing the firmware (or flash the latest from the guide) and see if it improves

I run 9.0.10j_something on my 7250-48p, seems to work fine. I just use POE and a few VLANS, though,

On the ICXs you need to set up DHCP separately for each subnet. So, yes, what you ask for is the default.
Click to expand...
Then I don't understand configuration. I turned off global dhcp using ip dhcp-client disable. Without that, switch was requesting IP on external vlan ve which I don't want. Also there are global options for gate and DNS, how I enter gate for subnet?

I want to basically achieve this:
  1. vlan 100 name EXTERNAL with ve 100 (no IP)
  2. vlan 200 name INTERNAL with ve 200 (no IP)
  3. vlan 300 name MANAGEMENT with ve 300 (ip from DHCP)
  4. All switch personal traffic (dhcp requests, ssh, web ui, tftp download, access to ntp) goes only using vlan 300
I suppose ve 100 and ve 200 will need some IP later so layer 3 to router work correctly. There could be static IP, but still I need to set separate GW, or not? Please help.
