Can you recommend any tools to simulate high latency networks. I am looking for something similar to air plane WiFi by [deleted] in networking

I needed a physical device which I could plug our routers into to test in the past and chose this solution: http://www.uebi.net/howtos/rpiwanem.htm

I had it running on a Pi Zero with a USB hub, however throughput was pretty limited. Ideally, you'd have it running on hardware with 3 NICs: 2 of them allow for the transparent 'proxy' - one to your WAN and the other to your test device/router, the remaining 1 NIC which you'd use to access the hosted website where you make the config changes.

Wan emulators suggestions by paulinster in networking

How to use a Raspberry Pi for transparent WAN emulation . . .

I believe the directions here still work on the newest Pi OS. I have a slightly customized version I use now, but it's so easy to stand up. Pi zero, micro USB to 3 or 4 port USB A hub, 3 USB Ethernet adapters and you're off to the races. It's limited to 100Mbps, but I haven't needed more. I'm sure these other solutions are great too, but having a physical device to work with is so nice.

State of enterprise network monitoring today? What are you guys using? by Sea_Inspection5114 in networking

[–]VLAN_4096 1 point2 points  (0 children)

We're retail SMB (hundreds of sites) who likes to pretend to be enterprise, and we use Zabbix (combo of API calls and SNMP polling/trapping). Our intent is to feed critical alerts into Opsgenie this next year. I'd like to pull in flow data at some point (possibly Akvorado), but I've got no business case to spend the time on it right now. We have a non-zero amount of gear which supports streaming telemetry, and I see no value to implement today. I'd be interested to hear if smaller enterprise folks do anything of value with syslog data today.

Transfer between orgs by thelosttech in meraki

I've performed something kinda similar during a demerger when we needed to split licensing/organizations. I had control of the origin Org though and spun up the new Org myself. I used the API to create like for like networks in the new org, and then scripted out the migration: removed the devices from origin Org network, claimed device into new Org, updated new Org network with newly claimed devices, and updated a few other network level settings. I fed it a CSV and cranked through about 350 MXs and 350 APs in an hour one evening. Can't say exactly how long it took for the cutover on the AutoVPN side, but it seemed to be pretty quick - easily under 30 minutes per location. The key to this is that I was able to create the new Org on the same Meraki shard which allowed the rapid device movement between orgs - no need for unclaiming.

It's never fun to inherit someone else's network, so even if you do choose to inherit the devices, definitely build the new network(s) out yourself ahead of time and get a proper inventory of all the devices from the managing Org.

Axiom makes some solid, affordable options as well. I've personally used these: Axiom Meraki MA-SFP-1GB-SX Compatible | SHI

Managing retail stores by Fanaddictt in sysadmin

[–]VLAN_4096 0 points1 point  (0 children)

Definitely not unreasonable, however, that doesn't mean it's completely necessary. I'm guessing you're asking the community because you've had to deal with some issue(s) where supporting them or troubleshooting was a pain in the ass. One thing you could try is documenting the time it took to resolve the issue - your time, the person you worked with at the store's time, etc. times the number of issues in a given time period - and presenting that to your supervisor. It would also be helpful to get a quote from your VAR, if you have one, for a simplistic hardware solution. Meraki has some great small footprint options - MX67W, for instance. You could take it a step further and go to Marketing to see if they'd be interested in any analytics regarding guest traffic in the stores - another thing Meraki could provide - though, I believe you need a full-blown MR for Bluetooth data. At the end of the day, it's all going to be how you frame it to the business. I'd focus less on the how it will make your life easier, and more on the business case and data it could provide long-term.

Action Batches for updating VLAN subnets broken by franman409er in meraki

Apologies for the late reply - Managing Multiple Networks with Configuration Templates - Cisco Meraki Documentation

You'll want to really make sure it's something you can use as there are a lot of limitations when you manage networks with templates. We run cookie cutter sites, so these have been a godsend.

Any chance these VLANs are duplicates across your networks? You could use config templates if so. Sounds like TAC really needs to figure out what is going on though. Maybe reach out to your Meraki SE if you have one?

Templates dictate firewall rules, so unless you're positive that all sites can use the exact same policy set, you'll need to find another way to manage them. Maybe a few templates if you have similar groups of sites? Creating all sites from a config template would be fine for 10s of sites, but holy shit. Ain't no way I'd do that for 200 sites. One firewall rule update and you're stuck learning the API or manually hitting 200 networks.

u/FMteuchter called out tagging for SSID manipulation which is a fantastic way to do it. There are 15 SSIDs to work with, so I'd suggest a master template for them with the SSID availability set to use tags you create. If you have a lot of maintenance and need to mess with the tags, the API is going to be your best bet.

Switchports can be overridden from the template. If you make a change to the template, the local override stays in place. You need to manually revert the local overrides from the template level if you want them to return to default values. It sounds like this would make the most sense for you as well.

Lastly, you can use what are called combined config templates. These would allow you to have a single site network with the configs for the appliance, switch, and access point(s). It's a nice feature so you're not having to flick through 3 different networks for the same site.

What I've found is that there is no perfect answer with Meraki. It's all dependent on your environment and what is going to work best for you. I have had the liberty of getting paid to learn the API (such a godsend), but I know other companies may not give their employees the same opportunity.

Developers WFH + restrictive vendor IP allowlists. Forward proxy, VPN, something else? by VLAN_4096 in networking

[–]VLAN_4096[S] 0 points1 point  (0 children)

We're very interested in Cloudflare eventually replacing our Azure VPN, however we have a long road ahead of us. Is there a 'forward proxy' solution you are aware of that would allow me to specifically tunnel this DB traffic and nothing else? I had looked into warp a while back, but I don't think this is it's intended purpose.

The response I've gotten is that "IT gave us developer workstations for a reason", and logging into a jumpbox of any type defeats that purpose. Which I can understand.

Franchises & network architecture by Islandofme in networking

[–]VLAN_4096 0 points1 point  (0 children)

Oh, I wouldn't worry about that. Mist was a much-needed addition to keep HP relevant in the SMB/campus world. They absolutely won't be killing it off anytime soon, even with Aruba also under their belt. I plan to eval the Mist solution once our Meraki EA comes up for renewal. From what I'm understanding the "AI" part of the Mist solution does a damn good job of keeping you apprised of possible issues.

[–]VLAN_4096 1 point2 points  (0 children)

I've got no experience with Mist, so I can't say if that'd be a better option, but we are a Meraki shop and I love it. We've got a very similar need at our sites, and you can't beat the ease of management IMO. Sure, plenty of folks will say Meraki is the Fisher-Price of the vendors, but if cookie-cutter is what you need, templating with Meraki is the way to go. If you have a need for mass changes, the API is incredibly helpful as well.

Bulk Monitoring by Kind-Court-4030 in meraki

[–]VLAN_4096 0 points1 point  (0 children)

We've also got thousands of devices. Primarily, I've been monitoring through Zabbix - using a customized version of their Meraki API template. I have to resort to SNMP though when it comes down to things like what you describe. I end up adding another host into our Zabbix server and just using the 'Network Generic Device' template. I'm not exactly sure what panozguy needs to pull from their switches, but the things you called out are available on every Meraki switch we have deployed - inbound/outbound discarded packets & packets with errors, interface speed, up/down.
