Greetings,
Can someone share their knowledge and experience to explain below troubleshoot scenario.
Customer has two existing L3 3560 switches. We need to connect 6 Moxa industrial switches to cisco switches as shown in pic attached. Customer doesnot want any vlan on moxa switches as there is only industrial traffic.
Customer has given defalt gateway of a.b.x.250
Now what additional configuration should be done on cisco switch. I created vlanx, int vlanx with ip as default gateway a.b.x.250 and configure port to moxa as trunk or access (as no vlan in moxa).
The link is up between cisco and moxa but no ping is working between cisco and moxa
Pls advise
Default Gateway | Managed Switch IP address | Moxa SWITCH NAME | ||
a.b.x.250 | a.b.x.200 | MOXA-SW01 | ||
a.b.x.250 | a.b.x.201 | MOXA-SW02 | ||
a.b.x.250 | a.b.x.118 | sw03 | ||
a.b.x.250 | a.b.x.119 | sw04 | ||
a.b.x.250 | a.b.x.120 | sw05 | ||
a.b.x.250 | a.b.x.121 | sw06 |

Hi,
I am not sure about the MOXA switch module number. As Moxa is having managed and unmanaged switch so we need the model number of the switch.
But try like this: (If the switch is unmanaged)
Cisco switch port configuration:
interface gigx/x/x
switchport mode access
switchport access vlan x
!
!
But try like this: (If the switch is managed)
Cisco switch port configuration:
interface gigx/x/x
switchport mode trunk
switchport trunk native VLAN X --> X VLAN is must match at both ends as a native VLAN ID.
!

Thanks everyone for your knowledge sharing, advise and suggestions.
The connectivity to moxa switches is established after creating default gateway for moxa vlanx on cisco switch and then the port on cisco switch configured with trunk and the moxa vlan ID made as native over this port.
On moxa the port changed to trunk to match.

since that is dumb device, i would suggest here to make (Cisco side as Access port) , make SVI on switch for that Access port example :
interface gi 1/1
description connected-moxa
switchport mode access
switchport access vlan 5
no shutdown
!
interface vlan 5
ip address x.x.x.x
no shutdown

Its Moxa EDS-510E-3GTXSFP-T. Its a managed Sw.
So on cisco sw.
I shall create a vlan x, interface vlanx, its ip address a.b.x.250 and on port make trunk with swicthport native vlan x and then on moxa make the uplink port with trunk and native vlanx. Do I need to define vlanx on moxa as well? Can I instead make cisco and moxa port as access port with cisco as vlanx access port?

If you like L3 connectivity, you need to have L3 interface on Moxa side also.
yes, you can make both the side access ports - belong to certain VLANs.

Yes, It will work but make sure that you will not receive DTP on the cisco switch and the MAXO switch will not react on DTP massage, sent by Cisco switch.
