Hello
for several weeks, I have encountered a problem on my network with switch 5120.
the stations lose the network and it comes back on its own after several minutes.
I am attaching you a screen print of my switch. Do you have any ideas because currently I have no more ideas on the subject ...

Thank you

Hi @Jvdv

By looking into logs , i could see strom control was acted due to multicast packet and some of MSTP messages as well.

Refer section Configuring storm suppression in below link for more information

https://techlibrary.hpe.com/device_help/H3C-Manuals/5120/5120-Configuration-Guide(R2215).pdf

It will be helpful if you share the exact time of the issue that can help , also share the firmware of the device

I work for HPE

I don't understand when you say: "Refer section Configuring storm suppression  in below link for more information" 

Where can it be found ? I'm sorry I can't find it in the doc.

one last thing. yesterday I had the message ARP table full 256. I modified the default time from 20 min to 3 min by issuing the command: display arp timer aging 3

How to enlarge this ARP table. Does the command below mean that the ARP table is erased every 3 minutes?

Thanks for your help.

Hi @Jvdv

As per logs interface GigabitEthernet1/0/1 is flapping continuously , can you tell me why this is happening ?

Refer PDF page 192 and serach with " Configuring storm suppression"

And query realated to ARP ,t he switch has capacity 256 ARP entries you cannot enlarge it.

arp timer aging 3 , says that how long switch keeps ARP in the table. If it not receive the response for 3 min means it will flush that ARP entry from its table.

I work for HPE

Hello

I am coming back to you regarding my problem.

My company has just called me back because peripherals and PCs are unable to connect to the network. Looking at the switch I have this alert again.

Oct 17 09:42:28 2021 SW_AVLCT_A %%10TPMB/4/ARP TABLE FULL(t): -DevIP=10.8.133.254; 1.3.6.1.4.1.25506.2.38.1.2.4.1: ARP table is full and number of items is 256.

How do I correct the problem if I cannot enlarge the ARP table?


Thank you

Hello

I am coming back to you because my problem is clearly identified. when my swtich's ARP table is full. I encounter network problems. If I can't zoom in beyond 256. How do I clean this table?

Thank you
