show mac-address only gives macs from uplink port

[Frank Grote]

Hi,

I have got a problem on several 5304xl switches. The command show mac-address only returns adresses learned from the iplink port to the core switch, in my case port A1. All local mac addresses are not shown. On an equally configured 5304xl it gives all mac, includingbthe locally connected. 

I have pinged all the connected clients, withot success...

In show-arp I get all the connected devices with port, but show mac-address is empty.

Any Ideas?

Thanks,

Frank
