Powerconnect 6224 causing havoc
Hi All,
I have a couple of powerconnects that are disabling ports on my cisco 2960's. Every port I plug the powerconnects into the port flashes for a split second then goes dead. Any ideas on what could be going on here? These switches are unmanaged.
Thanks!

On the Cisco to the following command and your should be able to figure it out.
show interface status err![]()
-![]()
disabled
Most likely it is because standards based switches linke PowerConnect forward the Cisco proprietary protocols. You can disable these protocols on the Cisco ports or block them on the PowerConnect port. Here is an example how to block them on the PowerConnect.
mac access-list extended blockCisco
deny 0000.0000.0000 FFFF.FFFF.FFFF 0100.0CCC.CCC0 0000.0000.000F
permit any any
exit
interface range vlan 5,6,10,11
mac access-group blockCisco in 1
exit
