Hi Everyone,

Current config on switch

vlan 120 enable name "VLAN 120"
vlan 120 port default 1/3

ip interface "vlan-120" vlan 120 ifindex 4

Port 1/3 is up and passing traffic

Need to confirm layer 3 interface is down because we have assigned no IP address to vlan 120 right?

Hi,
right, the ip address (in your network) is missing at your interface.

ip interface "vlan-120" address 192.168.120.1/24 vlan 120

But if this switch is only L2-device in this vlan (without any routing) than you don't need an ip interface.
You can delete it with:
no ip interface vlan-120
