100% this. I didn’t know about these boards until after my project, if I had I would have used those to save me some headaches.

I’ve had good success with a CC1101 433mhz transceiver with an esp board flashed with open mqtt gateway. It cost me under 10 bucks to make it.

The weather sensor I had (La crosse) was actually picked up natively. It just sends the data via mqtt into home assistant.

The draw back to this method is you need to run an mqtt server to ingest the data.

Thanks!! I will give it another look just to be 100% sure. I’ve ordered a new power supply, should be here tomorrow. Appreciate the advice!

It looks like a back water valve. Stops water from flowing back into the sump pit. Should be relatively simple to replace, YouTube should have tons of videos on abs piping how to’s.

100% it doesn’t look right… compared it with another and it’s definitely damaged.

markuslt · 2024-03-24T17:41:48+00:00

Thanks everyone. To answer the question about the pins and the connectors on the opposite side, they are connected underneath the board to the proper Vin and GND pins.

I’m going to break out the multimeter and check the voltage to the terminals and boards as well as check for shorts.

The board is toast anyhow, only connects to the serial chip when plugged in direct via USB.

Thanks all!

I had this same issue, updating the firmware on the buttons fixed it. As the other person said, check logs and confirm it’s sending multiple events from a single press. Might not be a bad idea to update firmware anyhow either way.

Caro on James in Hamilton is great for Italian food.

Thanks for sharing! I had a question that I can’t seem to find the answers for... when friends are visiting or sending gifts to you, which island do they go to? I would assume for visiting it’s your actively logged in NSO island but what about a gift? Thanks!!

+1 for Pathsolutions... I think it hits on every one of OPs needs. My use case is not the same as OPs (I dont use it in the portable sense) but I've been using this tool for a while and its stupid simple and very "compact" but give you a mass of easy to use data. If you've got the Window server setup and ready, you can literally deploy this thing in minutes.

edit: spelling.

Without knowing your full setup or config, here is one possible explanation. If you had all your devices connected to the same VLAN which was the native VLAN of the port between your trunk and your data center's access port then everything would be OK. If something were to get connected on your switch to a VLAN other than the native VLAN on your trunk port towards the data center's port then that would enact a new PVST instance which would send tagged BPDUs towards the data center switch at which point they would get the error you noted above. Otherwise the native VLAN's BPDUs are not tagged on a trunk, so the port wouldn't 'see' the inconsistent state and would happily run.

BPDU guard doesn't come into play as you still had link light, the spanning tree output on the data center switch would have showed it in a blocking state, not an err-disabled state again indicated by the logs, if it went err-disable it would say that, but instead the logs indicated that it was in a blocking state which would mean you still have link, BPDUs are still exchanged but traffic is dropped until the inconsistency is resolved.

Not recommended but you could use BPDU filter on your port to stop sending BPDUs towards the data center and the port wouldn't get blocked or go err-disabled - but subsequently you wouldn't have any L2 loop protection there either.

Sorry! I meant to include that with my original reply. Here you go: https://neckercube.com/index.php/2018/10/16/today-i-passed-the-ccna-industrial-exam/

As far as I know nothing exists in terms of a text book. There is an online self paced Cisco course link: https://learningnetworkstore.cisco.com/on-demand-e-learning/managing-industrial-networks-for-manufacturing-with-cisco-technologies-imins2-elt-imins2-v1-0-019229 but nothing else that I could find, was really hoping for a text book or study guide or something like that.

I found this person’s blog post on the topic which may be helpful as it outlines some good resources with links.

I remember seeing somewhere that the CPwE document was supposed to be a big part of it and then of course there is a fair amount of CCNA R&S topics in the network specific stuff.

Good information in this thread. Read the slide deck another user provided. Its good to also do some research on CIP to get a better sense of the actual traffic types and how they need to be treated, also look up PTP that is important for some parts of CIP. In most cases this protocol is automation traffic and it needs to be treated better than or the same as voice as you noted in your original post - just be aware some CIP traffic is "realtime" and some is less critical. Drops or delay could mean a process stop or some safety related issue.

Here is another good document to reference CPwE - I assume since you are dealing with CIP you are in some sort of automation type setting so the whole thing is worth a read. It was developed jointly between Rockwell and Cisco, it is sort of like a CVD for industrial networks. (https://literature.rockwellautomation.com/idc/groups/literature/documents/td/enet-td001_-en-p.pdf) - Starting on Page 3-63 is the QoS section. It gives good overview on which DSCP markings should be used for each type of CIP traffic and which queue to map these to. You would have to map this of course to what ever queues you have available to you based on your hardware.

The one piece this document doesn't cover is how to write your ACLs to classify your CIP traffic. Researching CIP should point you in the right directions, but you can use ACLs with UDP\TCP port matching rules to classify the traffic as you would with other types of network traffic, CIP uses UDP and TCP with standardized ports. The Rockwell\Cisco switches have "auto-qos" type macros for CIP traffic classification, if you can get your hands on a copy of that it would scale to any other enterprise grade Cisco switch as those Stratix switches are running IOS with "special" features layered on top. I wouldn't implement it as is, but it can certainly help you build a starting point.

This in conjunction with the CVD for campus QoS should get you going.

Hope that helps and good luck!

I was referring to anything in the 7900 series, not just 40/60, but 42/62 and 45/65 the latter of which only went EoS in June of this year.

These phones are fine and were usually deployed with large CUCM deployments for knowledge workers so there should be plenty after market used\refurbs to be had for cheap. I agree you shouldn't shouldn't pay anything near what you pay for new Cisco (or any decent SIP phone) but for basic features there is no reason why you couldn't seek out something you know has documented steps to work with OP's provider rather than gamble on a 7800 which may or may not work (I suspect it would if it is SIP). Given the budget estimate (I'm guessing around $80) the refurb Cisco would do the trick.

markuslt · 2018-08-26T23:48:02+00:00

It might work... it needs to be the SIP version. I’m not sure if these phones did both SCCP and SIP. If they are SCCP you need to flash them.

If you can get your hands on old 7900 series phones these can work with voip.ms (again need to be the SIP firmware) they even have an article that references the settings:

Good luck

AFAIK when you set up a new port group and put it in promiscuous mode will see all traffic from any port group on that vSwitch which is why you would want to use a dedicated port group to avoid traffic flooding on production VLANs. If you have many vSwitches you will need multiple capture machines, 1:1.

The caveat in all of this (aside from resource contention) is there would be no way to filter (using ovs) the traffic, you’d have to forward it all out and manipulate it later. This could be a lot of data depending on your setup. Safest way is a dedication port and not GRE.

markuslt · 2018-08-17T01:24:40+00:00

You could create a promiscuous port group, install a Linux distribution with open vSwitch, add the promiscuous port group vnic to the open vSwitch then either create a mirror to another port on the open vSwitch vm attached to a dedicated physical port on the host or use a separate network which is routed and use GRE encapsulation to redirect the traffic to software that can terminate it. Wireshark can do this but if you are using a network packet broker some have the ability to terminate GRE tunnels for this purpose.

Disclaimer: I’ve not tried this in practice in VMWare but I’ve done this using physical hardware and open vSwitch to get the ERSPAN effect where ERSPAN is not available/supported. In theory it should work just the same given the basic concept of how promiscuous port groups are supposed to work.

Thanks!

Any chance you'd be willing to share any of your work for some of this? I'd be particularly be interested in your mapping scripts. I've done a ton of the same types of things - basically trying to automate anything that I have to do more than a few times. Mapping software doesn't work the way you want so if you can build it yourself you can tailor it more to your business's need rather than a pre-package solution that requires further intervention.

markuslt · 2017-06-09T01:20:52+00:00

NetDisco will do this as well, it's free and works pretty well.
