An example of what he found was this entry *Total Entry Count Current / Peak ………….

His first thought was plan was to change the ARP Timeout to 50, as he saw that the ARP table was filling up. Jordan connected to my network via Team Viewer and started going through all the switches and reviewing config and checking logs. So after some chatting, I was put in touch with a Ubiquiti Engineer, UBNT-Jordan ( ). They are a great bunch of Australian based support personnel that have undertaken a range of the Ubiquiti Certificates (I couldn’t tell you exactly which ones) but they are very knowledgeable, and while they could find some issues they also reached out to Ubiquiti themselves to get some guidance on how best to proceed. This lead me to contact the Leader Support Team, I mentioned them in my why we choose Ubiquiti post. It did fix the issue slightly but didn’t get rid of it completely. I had been installing switches and upgrading them to 1.7.3 as step 1 of installing them, so I spent one night downgrading all my switches to 1.7.1 (online recommended as most stable current firmware). At first, I had read about some issues relating to the then current firmware of 1.7.3, an issue that effected uplink performances. I tried at first to figure out the cause of the issue myself, I thought it might be one switch or another causing the issue, but I wasn’t really able to figure out the exact cause. So I am sorry about that, I’ll do my best though. Though to be honest I am writing about issues I was experiencing in January, now were in May, and I was working 15-20 hour days during January to get all the work done so I am a little foggy about what issue caused what. The biggest issue I could find is that I was getting bad network performance, and I was seeing that every now and then an EdgeSwitch would go ‘down’ for about thirty seconds or more. About two weeks after the core had been installed, I had gotten around and managed to install most of the other 45 switches, I then came across another issue.
