Can't reach enclave switch on the MNGT network.

Created an enclave ( on our office network using a Cisco 2921 and overload NAT to the ISP Firewall (  The enclave NAT works OK but I can't get the management network ( out to the switch in the enclave.  I can't ping even from the CORE switch.

See the attached diagram.  MNGT  OFFICE  ENCLAVE

When you ping from the enclave router to, are you sourcing the ping from the enclave mgmt interface?

I believe you are having issues because of a Native vlan mismatch on 7 and 8. You've got vlan 200 as the native on 8 and vlan 1 as the native on 7.

Also you've got interface 9 setup as a trunk when I think it's supposed to be access

What is the result of a trace route from the core switch to

Tried the trunks with native 200 on both sides and with native 1 on both sides.... And it still doesn't ping....  How can the broadcast domain get interrupted between two switches connected by a trunk?  Maybe the vlans aren't allocated....
huffmanaSystem Admin and Network EngineerAuthor Commented:
Int 9 is working as a trunk.  I thought that it would be more secure than a mode access....  I think that the Firewall is tagging it's port as vlan 200.  I don't have access to the Meraki router :-(  I'm afraid to change it....
From the core switch vlan 200 can you ping the etherswitch vlan 200? Also, have you confirmed the vlan interface on the etherswitch module is up? Sometime an interface on the switch needs to be assigned in the same vlan for vlan svi to come up.

Got it, there was a port monitoring I forgot about!!!! All I had to do was look at UP/DOWN.

How stupid can I be - ignoring the obvious....

Thank you everyone....
Andy BartkiewiczNetwork AnalystCommented:
Well your not tagging vlan 200 to the router, its native. That's probably why its working. I don't think thats more secure however. Are the vlans defined on both the core and etherswitch?
