Hello,
Thank you for the prompt response! I will definitely replace the cable on Port 5. In the meantime, I have looked into the details of the SFP modules and obtained the following results.

* third-party transceiver
I think i might switch out the transceiver for a supported one

Pinging from the switch is a method to test L3 connectivity. It is not a good measure for switching or routing latency.
Ping uses ICMP echo requests generated by the control plane, the CPU. Actual switching and routing is done by the data plane in hardware.
And of course, pinging destinations beyond your network introduces a thousand other potential problem sources.
"Port 5 High-Collision or drop Rate" is an indication of a problem on that port, usually a defective cable. Depending on the nature of the problem it could also cause high latency on the path. Check error counters on both sides of the link, optical power levels etc to diagnose.
And yes, you should keep the firmware somewhat up to date.

Dear Community,
As described in the headline, this concerns an Aruba 2930F-24G-4SFP+ Switch (JL253A). I'm experiencing an issue where I encounter high latency when trying to ping, for example, 1.1.1.1 from the switch. These latency issues don't occur when I directly connect to the router and ping. I've already installed the latest firmware, version 16.11.0018. However, I've noticed that the ROM version is still running on 16.01.0010. Could there possibly be a connection here?
Additionally, I should mention that in the event logs, I see a "Port 5 High-Collision or drop Rate" alert.
The high latency is having a significant impact on all devices behind it, such as VOIP telephony and accessing the server via RDP, as everything runs very slowly and erratically. When the latency stabilizes again, things improve. However, it feels like the latency increases every minute.
