Hi
I'm not sure how to configure a new VLAN on my Cisco SG300-10 switch. I want to create a new VLAN (192.168.2.x) for AV and Security devices on port 2 of my switch. I can find directions for creating the VLAN, but what I can't tell is if I need to change my switch to Layer 3 addressing, or if there is a way to enable open (promiscuous?) communications between the 2 LANS or if static routing is required.
Any advice or tutorials?
Thanks and take care,
Shayne

Hi there,
Yes you need ip routing enable for inter-VLAN communication on the switch. The command you need is:
! set system mode router !
This will clear your existing configuration and require a reboot.
cheers,

Hi
If I enable L3 will I lose all my settings (LAGs, trunking, etc) and if so is there a way to back them up and restore them after?
Take care,

Yes, you will start with a black config after the reboot.
Take a look at the admin guide regarding taking a backup config:
...page 43
Take care that reloading a backup may reinstate the 'switch' mode. you are better off opening the backup config in a text editor and then pasting your Layer configurations back into the terminal.
cheers,
Seb.
