| Posted: 02 Nov 2021 05:00 PM PDT It's Wednesday! Time to get that crap that's been bugging you off your chest! In the interests of spicing things up a bit around here, we're going to try out a Rant Wednesday thread for you all to vent your frustrations. Feel free to vent about vendors, co-workers, price of scotch or anything else network related. There is no guiding question to help stir up some rage-feels, feel free to fire at will, ranting about anything and everything that's been pissing you off or getting on your nerves! Note: This post is created at 00:00 UTC. It may not be Wednesday where you are in the world, no need to comment on it. [link] [comments]  |
| Do organizations still shape traffic going to the internet? Posted: 03 Nov 2021 11:42 AM PDT There was a time where devices like Packetshaper/Bluecoat where popular for prioritizing traffic going out to the internet. I have worked for two enterprise organization now that have decided to pull these devices out. I now am doing work with a large enterprise org that still has there in. The devices are no longer supported and they are looking for a alternative. However, given that bandwidth is relatively cheap I feel that solution is just throw more bandwidth at it. Also with more applications becoming SaaS based, especially unified communication apps like Teams. I feel that these types of devices cause more headaches then they are suppose to alleviate. What do you all think or what are you experiences? [link] [comments]  |
| Where to find paid remote interns? Posted: 03 Nov 2021 05:38 AM PDT My (small) company has been trying to find remote interns with a networking background to hire but has had zero luck. Craigslist and Dice haven't brought us anyone with a networking background.. We prefer to stay away from recruiters and staffing agencies as they take a generous piece of the money we're offering the interns. Any recommendations? Maybe technical schools/colleges?

| VeloCloud Enhanced High Availability Posted: 03 Nov 2021 09:36 AM PDT Hi, I was going through VeloCloud Admin Guide. I have certain doubts to clarify to understand the two HA options. According to VeloCloud, If the active edge detects a different WAN connection on the standby edge it enters into "enhanced HA mode" and it leverages the HA failover link to establish an overlay tunnel over it. Else if the WAN links are mirrored on both edges it operates in "standard HA mode". My question is that, for standard HA mode, you don't need to configure anything on the standby edge device. We will only configure the active device enable the HA and connect both edges via LAN1/GE1 port. But for enhanced HA, since we will be connecting a different WAN link on standby device, do we need to configure static IP address (initial configuration) on standby device and then enable HA on active device? Can enhanced HA be achieved in MPLS only network? The network diagram that I have shared is for MPLS only branch site. Thank you [link] [comments]  |
| Looking for a switch with a good CLI Posted: 03 Nov 2021 08:07 AM PDT We have a Dell N3048 as the core L3 switch on our small in-house server rack, and I'm looking to upgrade. I absolutely hate the CLI on the DELL switch, and am looking for something better. As I am familiar with Cisco ASA's and IOS, my first choice is catalyst. I just got word from our vendor that the back order is 6 months. Can anyone recommend a line of switches with good terminal configuration, tftp backup, layer 3 functions, PBR and 1-10G RJ45 interfaces that isn't Cisco? Nothing cloud-based or centrally managed. I was going to research further with Dell since they have EMC now to see if there are any better options, but I wanted to get a broader perspective first. [link] [comments]  |
| phpIPAM import addresses and update everything Posted: 03 Nov 2021 07:38 AM PDT Hello Folks. I'ts been a while that I am using phpIPAM to manage my subnets. However, there is a annoying issue that bothers me since I started using phpIPAM: The xls import function doesn't update the records on PowerDNS server. If I import the xls with records that doesn't exist, it's fine, phpIPAM create the records on PowerDNS DB, but if I import a range with new PTR records, phpIPAM doesn't update them. Worse! It creates duplicate entries on PowerDNS. It's been now 4 days that I am searching the code to know how to fix this out without luck and I came here to ask if someone has fixed it, or at least, knows where to search. Any help is appreciated.

| Difference between Rockwell re-branded Cisco switches and IE series switches? Posted: 03 Nov 2021 01:35 PM PDT I'm having a problem with some of my manufacturing automation sites consistently buying Rockwell switches and Rockwell botching the configurations and not having latest stable releases on their Cisco re-branded switches. Most recently they dropped in switches that were doing RSTP instead of PVST or RPVST. All of my switching infrastructure runs on RPVST+ Is there really anything better that the Rockwell re-brands do that the Cisco IE series don't? [link] [comments]  |
| Is 70k+ requests good enough for a lowend computer? Posted: 03 Nov 2021 04:20 PM PDT Hi, I made a networking library to provide communications capabilities between two processes, so I made a program that tests how many packets I can send between 2 processes hosted on my local machine in one second and I got that 70k+ requests are being made inside a second. Is this good??? [link] [comments]  |
| Guidance on PTP/wireless bridge for non-profit Posted: 03 Nov 2021 10:49 AM PDT Hello everyone, I am looking for some guidance on a project for a local non-profit, looking to provide Ethernet and wifi to a few outbuildings 500-750ft away from their dmarc via a wireless bridge. We have clear line of sight and power at both ends but cannot run a hard line from dmarc to outbuildings, in addition I need local routing at the outbuildings in the event the bridge goes down. Since I am doing this free of charge as a favor to the non-profit I would like to spend as little time implementing and troubleshooting as possible. We do have a budget for reasonable hardware provided by some other benefactors, I just need to help them decide and implement a plan. My thoughts are: ISP modem > ubiquiti edge router > ubiquiti nanobeam AC <> ubiquiti nanobeam AC > managed switch > endpoints I'm not a huge ubiquiti fanboy but I do think their solutions would work well in this instance, but am absolutely open to other suggestions. Am I roughly on track? Greatly appreciate any input [link] [comments]  |
| Transceiver Polarity and polish Posted: 03 Nov 2021 03:27 AM PDT Hi there, A customer asked me some details about a QSFP+ transceiver and even after reading the datasheet I'm not able to get the info: - Polarity - Polish APC or UPC - Male or female (this is the only information that is clear in the datasheet) Could someone help me?? I really apreciate any help. This is the transceiver and the datasheet: https://media.digikey.com/pdf/Data%20Sheets/Finisar/FTL410QE4C_Spec_RevD1_3-17-17.pdf [link] [comments]  |
| Where can I find the startup config of N9k? Posted: 03 Nov 2021 03:28 AM PDT I am looking for the specific file and location in the file system. [link] [comments]  |
| Network Device Naming Conventions Posted: 02 Nov 2021 05:32 PM PDT I've been trying to figure out what naming convention would work best for our networking equipment. What do you guys use for naming conventions? [link] [comments]  |
| Posted: 02 Nov 2021 06:12 PM PDT Hello, I was attempting to setup a lab for a work project. I had two cloud VPC networks (GCP in this case) which each had a Bird instance running with a public IP. I attempted to peer them over the internet and have them share a private address range in first VPC network. I was able to write a filter which successfully changed routes "next_hop" to the public address of the Bird instance which is advertising the private routes. The issue is, on the second bird instance, which is receiving the routes (this is EBGP, a new AS number). I could not make the routes "reachable". I have the configuration for multihop working, and again it does appear like the actual peering and sharing of the routes works. I googled around a bit and I saw a few suggestions saying "every hop between both peers must have a static route in linux's routing table" Is this true? If so, I think this lab cannot happen since I'm going thru the cloud and a traceroute does not identify every hop. [link] [comments]  |
| Help me resolve this problem - and lets all learn from it Posted: 02 Nov 2021 11:33 PM PDT TOPOLOGY :
GOAL: to transfer data via rsync from ISILON to SYNOLOGY
I am unable to test connectivity directly from SYNOLOGY to ISILON because the latter has an old iperf version (2.x) while synology is already on 3.x. I can't seem to downgrade or upgrade any of them Please join the combo and lets debate! [link] [comments]  |
| Help with setting up a small office Posted: 02 Nov 2021 04:58 PM PDT Hello, I am helping out with setting up the networking for a small office that is currently getting renovated. I have a quick question, the router they have is a TZ370, and they have a SWS14-24 managed switch. I need to run new cabling through the roof/walls, and I was hoping to only need to run one cable per room. Each room will have multiple devices that need ethernet access, for example every employee workspace will have a computer and a voip phone, and some will have a printer. If I have a small switch in every room that then connects to the wall, which then connects to the SWS14-24, and then onto the TZ370 router, will I still be able to setup simple access rules when if multiple devices traffic will be coming through the same cable? Do I need to take any special steps, or will the router/switch be able to distinguish the traffic by itself? Or will I need to setup VLANS for this to work? [link] [comments]  |
