Today I experimenting a very strange situation... An extender-AccessPoint from tp-link brand disables ports for a 9200 Catalyst switch with the error of "err-disabled" due to loopback error detected.. I updated the tp-link device firmware and still peoduces same behavior, this was a RE450 model but with RE455 doesn't happens so maybe some bads on code about specifications RFCs or whatever... maybe a bug in iOS Cisco firm but thats rare. Will capture some traffic to look for some culprit

to enable ports again you know.. issuing commands "shutdown" problematic interface and "no shutdown" to come alive again did the trick

Thank you for showcasing this! You nailed the name :) The CSV feature is just picked up to be worked on. We should have it soon. I will include this video in the README as well if you do not mind? p.s. you might find the `-r <n>` flag useful too. when pinging a hostname, if it encounters <n> amount of failures, it will retry resolving it and tries another IP address behind that hostname. This is useful in case of companies that have a bunch of IP addresses responding to a hostname.

Hi Tony. I am very new in iperf and don't understand your point about downloading and uploading [speed](ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZUTx2t9tmK4.html). Could you please explain how you measure those? Thanks!
@thetechfirm
@thetechfirm Месяц назад
welcome and thanks for the question. upload and download tests can identify if the receiver, the port or Wifi has issues. for example if the access point has an awesome antenna and radio your downloads might be higher than your uploads, same with half duplex/full duplex mismatches.. doing just an upload or download only gives you half the picture. hope that helps

After exploring available macOS tools, if you open the Wireless Diagnostics app and go to the Window menu, then choose Scan, you get similar output (i.e., BSSID, RSSI, Security, etc.). As for a replacement AP, check into MikroTik hAP devices, which are highly-configurable and have perpetual licenses.

Hi Tony, Upon closer inspection, I noticed that each BSSID MAC address is indeed unique. It seems the access point might be inadvertently broadcasting its default SSIDs. If you'd like to keep using the current access point, I recommend factory resetting it and reinstalling the firmware (possibly an older version). Then, manually recreate the configuration to rule out any corruption. However, if you're looking for a quick solution or prefer a different approach, a WiFi 6 (802.11ax) access point from Unifi could be a good option. They're affordable and can be easily set up as standalone units without a controller. I'd suggest the Unifi U6-PRO unless you have specific requirements. I personally use three of them at home, and they've been working great. Please let us know how you get on.
@tonyfsvids

thanks for the comments.. in this case you are correct, but other times, the mac are all the same. i have tried resetting back to factory and going back a rev..
