Causes of Slowdown in Smart Switches and Solution

After configuring VLAN on the Hp Procurve 2650 switches I am using, I applied the untagged process as port to port and when the system was overloaded, that is, when the number of clients connected to the switch increased, a slowdown or even freezing occurred in the Vlan blocks I just created. I followed the logs and after 15 minutes Backbone collected the network and restored it.

When I examined the log records, I saw that port 49, which I had tagged, was blocked by the Backbone with the Blocked by LACP code many times. Then I examined the Backbone logs and examined the interface from port 1000 of the backbone to port 100 of my Firewall device and detected the jamming due to the traffic density. For this reason, I first stopped my IP cameras that caused heavy traffic.

When watching a live stream, 22 cameras require a huge bandwidth. As a result, the 100 ports in the firewall cannot respond and thus a narrowing occurs. With a simple example, a 10-lane road is suddenly reduced to one lane and traffic is blocked when the number of vehicles increases.

I developed the solution as follows, I removed the cable coming from the 1000 port of the backbone from the 100 port of the firewall and configured it to the 1000 port. The problem is fixed for now. Around 1 week I will subject the band to a challenging test again, let’s see what the result will be.
