| How did you ISP people get your start? Posted: 21 Oct 2018 02:12 AM PDT The ISP world seems foreign to the enterprise networking world. Does everyone start in a NOC creating tickets for downed circuits? [link] [comments]  |

| Why do DC in Miami always have bad connectivity to Latin America? Posted: 21 Oct 2018 03:54 PM PDT We've tried 5 different DC's in the Miami area and found they all suffer from fairly consistent issues servicing latin america. In virtually all cases we serve latin america far better from Altanta, or New Jersey, or even Dallas. Any reason that anyone can think as to why Miami dc's have so many issues going south. Looking at how the fiber maps work, it seems Miami area is a pretty big landing for latin america so to me it seems it would be the ideal location, but for us its not. We often see slower speeds, and more packet loss. Throughput and latency is something we track in detail using something similar to Internaps MIRO (we effectively ping and traceroute anything that connects to our network via all available uplinks and data centers and compare.) Thanks for your thoughts and time! [link] [comments]  |
| Posted: 21 Oct 2018 03:08 PM PDT Just a generic design question, assume there's a 5 story building, 2 IDFs on each floor connected to an MDF in the basement. Can it be designed with a layer 3 access design if the same VLAN is needed across all floors, such as a VoIP VLAN? How could such a design be implemented, is that a trade-off to the layer 3 design?

| Speed Variability on Virgin Media Cable modems Posted: 21 Oct 2018 01:37 PM PDT Using speedtest.net one minute the speed would be 70Mbps, then 142 Mbps and then 220 Mbps! All within a 20 minute time frame and all in the middle of the day (2:30pm) Laptop connected directly with ethernet cable to modem-router. Any explanation for this? [link] [comments]  |
| Is is possible to override dns except when on specific network? Posted: 21 Oct 2018 01:18 PM PDT I have dns record for my domain correctly up, however I want to override it locally to go over vpn. So far I know what to do, dnsmasq can handle this. However, I want to override it to another ip address when I'm on specific network. And I don't know how to make this happen.. Basically I want to go over VPN except when I can go over LAN. Any advice? [link] [comments]  |
| Posted: 20 Oct 2018 05:00 PM PDT I have 5 years experience as an Networking Engineer, holding a CCNP. I have recently began to travel heavily for work. On average I'm gone Monday through Friday, 75% of the year, if not more. I'm up for a raise at the end of the year and was wondering if anyone else does a lot travel and what you may feel is fair? Thanks in advance! [link] [comments]  |
| LACP issue between Juniper EX2200 and Synology box. Ports turn off if switch is rebooted. Posted: 21 Oct 2018 12:15 AM PDT I have a Juniper EX2200 and a Synology DS418play that are configured with LACP. When I was first testing the configuration, I had issues with the two ports on the switch being down for whatever reason. The ports were both enabled on the switch and still they behaved like they were administratively down. I tried to cycle the ports themselves and that finally brought them up. Later on, I rebooted the switch just to test that it comes back up and behaves as it should after a power loss. When the switch came back online, once again the LACP ports on the switch were off, no lights whatsoever. I had to manually disable then enable again to get them back up. Does anyone know what is causing this behavior? The Synology box is configured with the 802.3ad setting. (and it worked fine with a Cisco SG300 previously.) The Juniper switch is configured as follows: I am new to JunOS so I am still trying to figure some things out. Thank you. [link] [comments]  |

| I hate ASA - weird route issue Posted: 20 Oct 2018 06:11 PM PDT I really don't care for ASA firewalls, being a diehard palo gal and having pulled out more ciscos than I count and usually end up just keeping them running until replaced at jobs. Tonight I have a window that should be super easy, and I hit a snag before I even got to the tricky bit. sadly TAC is expired so they are no help. my ASA had a default gateway of X.X.X.132 which pointed over to a load balancer. LB's gateway was x.x.x.129 on the same public circuit. I am replacing the LB with another piece of equipment that needs to be configured differently, I can't use same design. Step 1 was to change DGW of the ASA to the GW of the circuit. X.X.X.129 I did this. ASA shows 0.0.0.0/0 x.x.x.129 as route, and last resort. no routing protocols. .129 pings. no problems. I do a trace to public IP from the asa and I get x.x.x.132 I delete 0.0.0.0 route, re-enter, reboot. same thing. I scour the config to see if there are ANY .132 entries. there is an object but it isn't being used. *headscratch* Coming up empty on google, or getting "how to setup asa with DHCP" things. Would be most appreciative of any help. *grumble grumble palos... * @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ AHAHAAAA! - RESOLVED. Well fooled me. So the device in question the previous admin had a patch panel in the 2 post racks about 8 feet away from the server cabinets and half the equipment was in 2post and half the equipment was in cabinets hopping across patch panels which were convienently mounted about 15ft in the air. Shoulda worn my server racking heels today! Looks like he trunked a vlan for external side of ASA to another vlan holding the actual circuit and it was bridging.... moved cables around and problem solved. The moving of cables was easier (albeit messier than i'd like, I like an easy backout plan where you move cables 1:1 back to device if you have to) and my new device built 2 of it's 3 tunnels to load balance. just need to troubleshoot the last and we are done!

| Fiber - multimode vs singlemode? Posted: 20 Oct 2018 04:22 PM PDT Hi, We ran Remee fiber - It is 6 strand, 50 micron. Remee - 11-006-12S-AANOOF 11-006-12S-AANOOF 6 Fiber OM3, Indoor/Outdoor Riser Rated Type Buffer. This was run in 2012 - we never terminated it and am getting ready to start using it. To confirm with a multimode fiber, one fiber is for TX & one is RX? So with a 6 strand fiber, we would have 3 usable connections for our SFP on a cisco switch? Also - this fiber is limited to 1GB (is this correct)? The fiber was pulled with a number of Cat6, Coax, etc so pulling another fiber cable between buildings might not be workable without repulling the entire bundle. Any information would be great.
