SG250-08 Layer 3 Routing?

cma-2020
Level 1
Level 1

Living in the COVID world, I am working to affordably segment a couple of different work from home networks from a personal network.  I have purchased a set of SG250-08 switches in order to set-up vlans (see attached). 

 

I am trying to configure L3 routing on a SG250-08 but cannot find the option to do so in the web UI (as defined here - https://www.cisco.com/c/en/us/support/docs/smb/switches/cisco-small-business-300-series-managed-switches/smb5073-switching-to-layer-3-mode-on-the-sf-sg-300-series-switches.html). Does the SW250-08 support L3 routing?

 

Ultimately, I am trying to get IP routing configured between a SG250-08 and a Netgate SG-3100.  From within the SG250-08 web UI, I am able to ping the IP address of the physical interface of the SG250-08 which is cable attached to the SG-3100 as well as the physical port on SG-3100.  The physical interface is configured as no switchport, which to my understanding is should enable it as a L3 interface. 

 

I have the vlans set-up and working (am able to ping between the access ports and the access ports to MLS SVI's), but am having trouble routing between the MLS and router.  I just can't ping the SG-3100 from an access port from any switch in the network.  Thoughts on how to resolve?

If you want to make Layer 3 SG250 - follow the below thread: - start with a simple config and test it.

Inter VLan routing is working beautifully with the SG250, but I can't figure out how to put it in L3 System Mode so I can set a routing protocol with it (i.e. RIP2v2) in order to configure L3 routing with my Netgate/PfSense SG-3100.

 

Apparently the SG250, using either the web UI or CLI, does not appear to support setting L3 System Mode, even with the latest (image_tesla_250_2.5.5.47") firmware upgrade (see attached).  I followed what you proposed, but the CLI option does not present itself with this model

 

From the Tech Talk videos, their demos show use the SG300 to set the L3 system mode.

How about under IP configuration/IPv4 interface and then enable IPv4 routing?
