Cannot ping/access to sg250 over vlan

[Sokmeng]

Dear team,

Currently, I completely to implement 5 x SG250-26P into production, and the operation working well. Buty, the problem is I cannot ping or access to switch over vlan (vlan11, device-mgt) from another vlan, even I try to ping from firewal ( vlan provider). Below is my classic nework flow:
ISP ----> Router ----- Firewall(Vlan provider)-------SG250-26P ----- Internal-Lan (STAFF)

In the attach is my currently switch config. I hope all of you can advice with this issue. Thank in advance.

Best regards,

Sokmeng,

Try checking out if the interface to the GW is a trunk and if its allowed the vlan 11, and if its an access port if its on the right vlan. Also the native vlan on the other devices if its the same.

Dear Giovanni,

Thanks for your reply. After rechecked, the problem is vlan setting on firewall and now the problem is fixed. Thank too much for your hint.
