errdisable detect loopback on trunks

[d-mark]

Hi,

on interfaces configured as trunk, like

interface GigabitEthernet 1/0/1

switchport trunk encapsulation dot1q

switchport trunk native vlan 11

switchport mode trunk

!

and 'errdisable' detect and recovery configured for all causes with a timeout of 300 seconds a looped link is not detected. This is not the behavior I expected. Am I missing something?

I'm using Cat 3750 with 12.2(25).SED1.

If someone could help me, this would be fine.

thanks in advance and kind regards

Mark
