| Aruba -- Force all APs / Clients to IDC cluster Posted: 30 Oct 2021 11:24 AM PDT Looking for some help from anyone with experience with Aruba wireless infrastructure MM / MDs. We have two clusters configured ... one at our primary DC with Primary MM and 4 MDs then one at our secondary DC with Secondary MM and 2 MDs. The clients and APs are "load balanced" across all MDs (I'm not exactly sure of the load balancing mechanism though). We will be moving equipment at our secondary DC and I'd like to force all clients and APs over to the primary cluster during the maintenance. Does anyone know of a way to accomplish this?

| Posted: 30 Oct 2021 09:58 AM PDT Given that multiple clients in a single collision domain can impact performance, and given that a WAP functions as a single collision domain, does it follow that more clients on a single WAP will increase the number of collisions that take place, and if so, what performance impact might that realistically have? I see WAPs that advertise support for 300+ clients. Would supporting, say, even half this number cause performance impacts from collisions? Or is this more theoretical with little real world impact? Thanks! [link] [comments]  |
| Embarrassing troubleshooting stories Posted: 29 Oct 2021 11:02 PM PDT There was an issue with a link between two devices today, and I was lucky enough to be on-site 😑. Mind you, this is a data center and I'm new to this type of environment. Long story short, I wasted about 3 hrs looking at the wrong port on one end because I misread the fiber patches panels. I was also going down a rabbit hole on the other end because the label on the fiber was not updated after it was moved to a different patch panel. There were about 30 people on the call, including my boss and his boss. Any one have any embarrassing troubleshooting stories???? [link] [comments]  |
| trouble figuring out which job to take Posted: 30 Oct 2021 08:24 AM PDT a couple of weeks ago I was let go from a small msp. I started interviewing like crazy and got 2 job offers on the same day and no clue which to take and am curious what you guys think, the pay and insurance is the same on both:
What do you guys think? [link] [comments]  |
| Posted: 30 Oct 2021 04:35 PM PDT Looking at Mellanox switches right now. I can't seem to find anything that indicates if Mellanox Onyx OS supports port security like Cisco or Cumulus. Can anyone confirm? Thanks in advance. [link] [comments]  |
| ASR920 port down even though LEDs are green and remote end says link up Posted: 30 Oct 2021 12:56 AM PDT Hi all, I have a bit of a headscratcher here. We have two ASR920 that we use for BGP peering with our ISPs, we're in the middle of setting up a new set of Fortigate firewalls and I'm having issues connecting them to the ASRs. When connecting the devices I get green LEDs all-round and the fortigates mark the links 1000fdx, but no traffic is passed, the LEDs are solid green, no activity. If I look at show int gi0/0/x the port and protocol is marked as down, not errdisable or anything just down. I've tried to shutdown the ports overnight, but it made zero difference, I've also tried to place a switch between the devices again with zero success. On the ASRs the ports are in a basic ethernet service instance, same config as the ports to our current checkpoint firewalls. The ASRs are licenced for 24x1G + 4x10G, so it shouldn't be a licensing issue. I originally tried with the 10G SFP+ interfaces, but I'm having practically the same issue with the copper 1G ports. Let me know if you need any config from either the ASRs or the FGs. EDIT: Seems the concensus is reboot (and firmware update) the routers, thanks! I'll report back on this post when I've rebooted them, will have to schedule a few hours service window, as someone decided to not setup HSRP on all service instances... [link] [comments]  |
| Posted: 29 Oct 2021 08:17 PM PDT What are your thoughts on Alcatel Lucent networking equipment. I've been using it for about a year and really like it's cli. I'm just curious cause I haven't seen many posts about them. [link] [comments]  |
| Simple Bird ibgp config doesn't work Posted: 29 Oct 2021 05:37 PM PDT Hi, I'm setting up Bird on two hosts. Second one got correct routes but first one got unreachable routes. Network scheme: First host: Second host: First host routes: Second host routes: Logs from host 1: [link] [comments]  |
