Unable to using port-mode autolearn at 3COM 4500
Hello,
I have 3COM 4500 switch
when trying to config the port security via limit the max mac address learn
It showing the following error message
--
[4500-Ethernet2/0/23]port-security port-mode autolearn
This mode can not be configured, please undo all fabric-port first.
---
It was work fine when the stack was not stacking, but fail to run this command after stacking the switch.
What problem here and how to solve it?
Thanks!

Re: Unable to using port-mode autolearn at 3COM 4500
I got some reason why because it is using stacking now so fabric-port was enabled.
Did is means "port-security port-mode autolearn" will not able to learn. My purpose is limit number of MAC learn by each port.
Thanks1

Re: Unable to using port-mode autolearn at 3COM 4500
Is the software on the switches up-to-date? (03.03.02p21)
Have you considered using port-security with a RADIUS server? And using 802.1X?

Hello,
yes, the software is already up-to-date.
It using local 802.1x auth without external Radius server assistant.
