| Cumulus Networks Certification (CCONP)? Posted: 29 Sep 2019 09:39 AM PDT Anyone researched or, better yet, taken the Cumulus Certified Open Networking Professional (CCONP) exam? I think this is a really interesting exam and am looking to see if anyone else has any thoughts on its value (for those who deploy Cumulus and general networking value). How did you go about studying for the exam? How was the online exam proctoring experience? [link] [comments]  |
| Open Source Traffic Logging/Visualization Posted: 29 Sep 2019 02:59 PM PDT I run a small DC at my school (roughly 500 IPs) with a Juniper edge router/distribution switch down to 5 access switches. OSPF up to my next hop. I want to be able to log and visualize data from hosts so I can see how active IPs are (mainly to see if I can shut them down). I'd like to see E/W traffic if possible, but N/S would do. Anyone have any suggestions? [link] [comments]  |
| Cisco ASA loop broadcast packet Posted: 29 Sep 2019 11:56 AM PDT I have small office where running cisco ASA ASA5506 and version 9.4(1) So i have found very interesting things in LAN where if i ping 10.1.1.255 This is how i stop strom, clearing conn in ASA I believe cisco ASA participating to amplify this storm. here is the basic config snippets of ASA Notes: I believe one of above option has something to do with this storm.

| Roaming with two different Controllers (5520 and 9800) Posted: 29 Sep 2019 10:41 AM PDT I was wondering if anyone in the subreddit has deployed a mixed environment with the 9800 controllers. Im currently planning on deploying the 9800 with 9100/3800s but we currently have 3500s and 2600s which I need to keep them on 8.5 with the 5520. I'm planning getting the controllers in the same mobility group and rf group (i'm taking a bet with that is going to work) but these access points are also in flexconnect so i need to see how they roam in different flexconnect groups. This is just with PSK currently so I'm not very worried on issues ill have with 802.1x roaming at the moment (that is a later problem but hopefully those 3500s and 2600s will be replaced by them) This is just a temporary problem which i have couple solutions such as just finding the money so that we dont have a mix environment or moving access points so they dont do inter-controller roaming.. Edit: If i can't get rf grouping to work well then i need to do static configurations.. which will be a pain. Add to the question... if you deployed it in this mix environment how does RRM/Cleanair react Im just trying to see if anyone has faced this challenge and found a solution. I'll be testing this in a lab in the next couple weeks so we'll see. [link] [comments]  |
| Networking question to reach an api server Posted: 29 Sep 2019 12:29 PM PDT I would like an app server "A" to reach the API server (located at Network C) via another network (network B). What is the best way to reach ? it must be a two way communication. Let me explain. Three networks are involved( Network A,B & C). What is the reliable way to design this infrastructure? Network A [] > Network B [] and network C [] Here is what I am considering: Create point to Site trust VPN relationship between A & B . There is Site to Site VPN between B & C that already existed . What is the reliable way App A located in Network "A" to have (port 443) two way communication to the API server in "Network C". Thank you for reading. [link] [comments]  |
| Need help to find source of high latency/pingtimes Posted: 29 Sep 2019 03:50 PM PDT for 3 days now my internet is unbearably slow and now decided to try to find out what is causing it. For this i used PingPlotter. As i understand it the problem does not seem to originate from my end but starts at this ip. I don't know if this belongs to my isp or if it is something else. Here is also a image of the "trace"? (im sorry, i don't know if im using the right words here) any help is greatly appreciated [link] [comments]  |
| Will VLANing 100% isolate traffic in this scenario? Posted: 28 Sep 2019 09:22 PM PDT So without getting too far off in the weeds here - I have two locations. Site A and Site B. A switch at Site A has as a direct run of fiber 1 mile to Site B. I'll be introducing public WiFi at Site B. I'll be using client isolation on the public WiFi SSID, as well as tagging all traffic on that SSID with say VLAN500. The AP will be connected to the core switch. Port will be an access port on VLAN500. The uplink port on Site B's switch will obviously be a trunk port passing all VLANs. It will trunk all traffic back into Site A, where i will configure another port on Site A's switch as an Access Port on VLAN500, which will then go to a separate firewall. Is there any risk whatsoever at compromising the internal LAN? I'll have some extremely sensitive data on the internal network that shares the same switch to get back to the internet at Site A.

| Where to learn dynamic routing with BIRD? Posted: 28 Sep 2019 09:29 PM PDT I don't exactly have a specific question but rather am looking for help finding good resources that are specifically for learning dynamic routing with BIRD. Ideally, I was hoping to find something structured a bit like a course, or at least some problems to solve to guide my reading. If this breaks rule 5 then I apologize. I've been working for an SDN company for a while now but I don't have a background in Net Dev. Thank you in advance. [link] [comments]  |
