Hi I am newbie here. I am hoping someone to please help me for setting up the VLAN's in my Cisco SF-302-08P. I already configured this switch in L3 mode and I already created the VLAN2 and assigned the port to  VLAN which are GE1 and GE2 untagged.

However, If I would create in IP Configuration--------IPV4 Interface and I add the VLAN2 and setup the IP Address 192.168.2.254 with Mask 255.255.255.0, After I click the apply button, It looks like nothing..just loading and I noticed that stopped not pinging the default VLAN1 which is 192.168.1.254.

I tried to power off the switch again..after loading I can access again the GUI but still no luck to create or configure an IP address for the VLAN2. I used this version of firmware sx300_fw-14502.ros and also I tried to downgrade to Sx300_FW-1.1.2.0 but I have no luck still the same issue I encountered.
