Hello Eemoon,

It could be a number of things but based on the output you have provided, it appears that your management interface is in vlan 10. I would suggest changing the management interface to vlan 11 or make sure the switch has a def gateway assigned. Also, as I do not know your network, please consider what will be affected when making those changes.

Are you sourcing your pings from vlan 11 when pinging from the switch? You can also use tracerout to see where pings are failing.

I hope that helps. Let me know if you have any questions
