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

 

http://www.h3c.com/portal/Technical_Support___Documents/Technical_Documents/Switches/H3C_S3600_Series_Switches/Configuration/Operation_Manual/H3C_S3600_OM-Release_1702%28V1.01%29/201005/676114_1285_0.htm#_Ref161823919

 

 

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!

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

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.
