I am trying to configure a Vlan (Vlan10 in my case) to work with GigabitEthernet1 interface which is connected to a Cisco LoRaGW PoE interface but i'm unable to bring it up despite trying various things.
Any help is really much appreciated.
Here's the output of few commands.
IR829#show ip int br Interface IP-Address OK? Method Status Protocol GigabitEthernet0 unassigned YES NVRAM down down GigabitEthernet1 unassigned YES unset down down GigabitEthernet2 unassigned YES unset up up GigabitEthernet3 unassigned YES unset down down GigabitEthernet4 unassigned YES unset down down Wlan-GigabitEthernet0 unassigned YES unset up up Async0 unassigned YES unset up down Async1 unassigned YES unset up down GigabitEthernet5 unassigned YES NVRAM administratively down down Cellular0 unassigned YES NVRAM up up Cellular1 unassigned YES NVRAM down down NVI0 127.1.3.2 YES unset up up Virtual-LPWA1 unassigned YES unset up down Vlan1 192.168.2.6 YES DHCP up up Vlan10 192.168.1.1 YES manual down down wlan-ap0 unassigned YES NVRAM up up

Is it possible that this particular 829 doesn't have the PoE module?
If you do a show inventory do you see the following line? NAME: "IR800-IL-POE", DESCR: "POE module"

I see that the g1 interface is down when you ran show ip int br on the 829 the VLAN interface will be in a down state until a port on that VLAN has a device connected and the port is up/up.
If you want the VLAN interface to be active regardless of any device connected use the no autostate command on the VLAN interface.
If you have the device connected to g1 and are expecting it to be functional I would start by looking at the physical layer, cabling, the port itself, PoE.
Hopefully this is helpful.

Ben, thank you for your reply. Issuing the command no autostate on the Vlan 10 interface brought it back to life.
IR829#show ip int br Interface IP-Address OK? Method Status Protocol GigabitEthernet0 unassigned YES NVRAM down down GigabitEthernet1 unassigned YES unset down down GigabitEthernet2 unassigned YES unset up up GigabitEthernet3 unassigned YES unset down down GigabitEthernet4 unassigned YES unset down down Wlan-GigabitEthernet0 unassigned YES unset up up Async0 unassigned YES unset up down Async1 unassigned YES unset up down GigabitEthernet5 unassigned YES NVRAM administratively down down Cellular0 unassigned YES NVRAM up up Cellular1 unassigned YES NVRAM down down NVI0 127.1.3.2 YES unset up up Virtual-LPWA1 unassigned YES unset up down Vlan1 192.168.2.6 YES DHCP up up Vlan10 192.168.1.1 YES manual up up wlan-ap0 unassigned YES NVRAM up up
However, the GigabitEthernet1 int is still down.
The device itself is working fine as I have access to another production IR829 for reference and when I connect the device to it via PoE, the device boots up fine. I've tried to match the configs b/w the 2 routers but looks like i'm still missing something.
Any ideas?

A wireless lora gateway is connected to it (https://www.cisco.com/c/en/us/products/routers/wireless-gateway-lorawan/index.html) so that the IR829 can act as a backhaul.
When I connect another router which has been running in production for few months, this gateway boots up fine so i'm wondering what the problem could be with my router and the cable is fine (tested it few times with my laptop)

Ben, you're right on the money. How stupid of me to not checked this router properly before pulling my hair out.
Thank you for your patience and replies.
