Is secondary IP supported on SG-300?

charlie.rhodes · ‎12-05-2013

I want to have devices with IP addresses from 2 different subnets allowed on the same VLAN and use the VLAN interface IP as the default gateway for thode devices.

With a L3 Catalyst switch, I would just add a secondary IP address to the VLAN interface. Can I do this on the SG-300?

You can set up 2 ip address on a single VLAN, yes.

Hello,

My name is Nikola and I am an engineer from the SBSC team.

Yes secondary IP address is supported on SG-300 switches.

First, you need to change the switch from L2 to L3.
Then you can add interfaces onto same or different VLANs.

For the syntax of the CLI commands, please refer to this guide:
