Which subnet for the VLAN?

Hi,

I have an HP 1920 switch in which 3 VLANs are configured. How do I know the IP subnet associated with the specific VLAN?

Best Regards

Re: Which subnet for the VLAN?

If your switch is configured to have an IP Address for a particular VLAN interface (this is called SVI) then you can understand the subnet that address belongs to.

Example:

VLAN id 10 -> IP Address 10.0.10.254 with Mask 255.255.255.0 (/24) -> Subnet 10.0.10.0/24 -> the edge devices landing into a port in Access Mode (untaggged) set in VLAN 10 need to be addresses within Subnet 10.0.10.0/24 with D.G. set as 10.0.10.254.
