T1600G-28TS CPU spiking throughout the day
T1600G-28TS CPU spiking throughout the day
2020-06-07 19:57:29
Hardware Version: V3
Firmware Version: 3.0.5 Build 20200109 Rel.39834(s)

Switch T1600G-28TS being used only with L2 features and configured with Remote NTP, Remote SYSLOG and SNMP V2c. On syslog server we can see several records of CPU RISING THRESHOLD events, without any plausible reason. We are using only 6 ports on the switch and the traffic is not heavy. Is this a known behavior/problem? Any recommendations how to avoid it?

 

regards

Re:T1600G-28TS CPU spiking throughout the day

@MHenriques 

 

It seems that you will get the warning every 20 minutes or 25 minutes. As I knew, SNMP may cause the high CPU usage. You can check if your SNMP software also get some information from switch every 20 minutes or 25 minutes.

 

And this will not affect your switch working. Because it doesn't keep high CPU all the time. The switch did not hang.  The L2 traffic will not pass CPU so your network still can work normally.

@Andone Thanks for your reply. We are indeed using a SNMP Manager (The Dude) to keep an eye on the backbone switches of our network. But the TP-Link switch is the only one alarming high CPU usage. I will change the polling interval to see if the errors follow.
