MAC Address not captured on switch ports

I would expect to see all devices MAC addresses displayed in switch interface, as per this

But I do not see on some ports like per this

And the only way I can find them is to ping IP

and then show arp

 

Which is not always ideal

Any ideas why? Is it a bug?

Procurve WB_16_05_0007 on HP 2920

I really cannot figure out the numbering of the firmware WB.16.0X

Re: MAC Address not captured on switch ports

Hi There,

Do these ports have port-security enabled ?

Also, even though this very behavior doesn't show up as a bug the software release WB.16.05.0007 is old and quite a few new releases have come up. You may consider doing an upgrade to a newer version and see if the issue gets eliminated.

Updated to WB_16_08_0003

Not much difference

 

there-but-not-thereport-security is at default (it was explicitly not touched)

Can you share the configuration (sanitized)?

Or yourself can check the mac aging timer, if that is set to too low.

Re: MAC Address not captured on switch ports

I do not have mac-age-time configured explicitly, so whatever defaults are

At this point, I suggest you to log a case with Support team to investigate on the same.
