Hi,

Some of our X440G2 switches show high temperatures (around 90°C)

Fans seem to work. So when looking at CPU usage, I’ve noticed the HAL process has a max usage of 99,9% and a constant 20%.

After reading this article I was wondering if the bootROM on the device should get an upgrade.

Currently, IMG version is 22.7.1-2, bootROM is 1.0.1.8

Is it good practice to do the upgrade? Where can I obtain the file?
Maybe there are other ways I should try prior to upgrading?

Thanks!

HAL usage could be high due to different reasons:

high port numbers (especially if you have stack) # X770 with default config has 30% HAL CPU usage
bulk SNMP polls put switch into stress
frequent STP TC
MAC moves
etc

If you want further investigation this, please raise case in GTAC.

I’ve applied the ACL from

by running

configure access-list flooding.pol any

Unfortunately, HAL proces CPU usage is not affected.

Great, this I was looking for. Thanks

Link local multicast is the most often reason of the high CPU utilization by HAL.
