Routing on IR8340/K9

[HatDauNho]

Hi team, 

Besides the WAN ports on the IR8340/K9 device, the LAN ports also support routing (can operate at Layer 3).

Thanks team

Hi Mark Elsen,

Can you share the link ?

Thanks

   - @HatDauNho      There is no link to confirm this , any router will accept routing on it's lan ports but it must be configured
                                 as a layer 3 port first , otherwise you can not make a path to the outside world (WAN port)

Hi Elsen,

I asked Cisco's AI, and it said that all LAN ports, except the WAN ports, are only Layer 2. To configure Layer 3, do I need to set up an SVI on the router?

Thanks

  - @HatDauNho     Yes, that's the best thing to do, then put the particular port in the corresponding vlan,

Hi Elsen,

But what I want to ask is whether it’s possible to assign an IP directly on these ports, or can it only be configured through an SVI?

Thanks

according to https://www.cisco.com/c/en/us/td/docs/routers/ir8340/software/configuration/1717x/b_ir8340_cg_17-17-x/m-iox-application-hosting-17-8.html?bookSearch=true#Cisco_Task.dita_7e31bcaf-3f52-404c-9a56-b9fca1a841ed
the IR8340 supports 

Step 4	interface type number Example: Device(config)#interface gigabitethernet 0/0/0	Configures an interface and enters interface configuration mode
Step 5	no switchport Example: Device(config-if)#no switchport	Places the interface in Layer 3 mode, and makes it operate more like a router interface rather than a switch port.
Step 6	ip address ip-address mask Example: Device(config-if)#ip address 10.1.1.1 255.255.255.0

the reason in this procedure is to prepare for application hosting,
but it does show the ability to attach an ip-address to a port directly
