| Interactive Network Visualization Posted: 30 Oct 2021 08:22 PM PDT I'm looking for an Interactive Network Visualization Software (like the title says). I am an Infrastructure Architect for a blended Network that combines IT/OT, on-prem, cloud, and a fiber infrastructure that spans over 4000 miles of fiber in multiple states. We have over 1500 devices on our various networks and OT enterprise. What I'm looking is something truly Interactive. We user various softwares for IPAM, NMS, threat security and SIEM, but have no single Network map that could display everything. Has anyone seen or have used anything that can display a Network, in an Interactive way? By Interactive I mean something like I can click on a switch and see all VLANs, and select a VLAN to see if it traverses all switches end to end. Or select a trunk port and see all VLANs on that trunk. Or select a device and see the path it takes through the network to see what has access to see that device. Does this software even exist? Any experience or ideas would be appreciated. [link] [comments]  |
| Excessive total output drops coming from 3650 uplink. Where to start? Posted: 31 Oct 2021 12:10 AM PDT This is the configuration on the interface: sh int xxx x/x/xxxxxxx is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is xxxxx (xxxxxx) Description: UPLINK to xxxxx MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec, reliability 255/255, txload 10/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive not set Full-duplex, 1000Mb/s, link type is auto, media type is 10/100/1000BaseTX SFP input flow-control is on, output flow-control is unsupported ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:27, output 00:00:00, output hang never Last clearing of "show interface" counters never Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 5xxxxxxxxx I don't even know where to start, but on the adjacent link, FIFO queuing is in place.

| Posted: 30 Oct 2021 11:04 PM PDT How dangerous are PPPoE Ethernet frames? I've always assumed you can tag them and put them on a VLAN and have them arrive at a Linux interface running pppd. If I do this, can anyone on the Internet now get on that particular VLAN? Are they safely encapsulated inside PPPoE, or is it riskier than that? My site has a dumb DSL to Ethernet modem at one end but the actual machine running pppd is at the other end, so the two talk over a VLAN. That's not going to fly though unless the nature of PPPoE means the only attack surface is pppd itself, and not the VLAN or switch in between. [link] [comments]  |
| Radius - enterprise WIFI not working Posted: 30 Oct 2021 08:33 PM PDT Hi all, Trying to set up WPA2 EAP with Windows NPS + Unifi WIFI but running into issues that I don't know how to troubleshoot further.. I can't post screenshots so I am going to skip past the setup for now and keep it simple: -Radius Access request is sent out from the NAS and received on the Radius server -Radius server replies with Radius Access Challenge -Request and Challenge are repeated half a dozen times until the client finally reports "Unable to connect to this network" or similar. Tested with laptop wifi, smart phone, desktop+USB wifi stick. All are the same. I verified this by taking PCAPS on the firewalls VLAN interface which is connected to the wifi workstation, a PCAP from the Radius server using Wireshark, and a PCAP from the Access point.. The AP itself shows the Radius Access Challenge packet. Is my understanding correct that the radius server is asking for more info (challenge) and not getting it? Tried to take PCAP from workstation WIFI interface but not able to see any packets. [link] [comments]  |
