IP Subnet-based VLAN
IP subnet-based VLAN entries can be configured from the
Configuration
>
VCL
>
IP
Subnet-based
VLAN
menu path. With this method, a VLAN membership is defined by the subnet to which a device's IP
address belongs.
This page allows adding, updating and deleting IP subnet to VLAN ID mapping entries and assigning
them to different ports.
VLANs are layer 2 constructs, compared with IP subnets which are layer 3 constructs. In an environment
employing VLANs, a one-to-one relationship often exists between VLANs and IP subnets, but it is
possible to have multiple subnets on one VLAN. VLANs and IP subnets provide independent Layer 2 and
Layer 3 constructs that map to each other, and this correspondence helps in network design. Note that
this page shows only static entries.
From the default page, click the
Add New Entry
button to display the entry fields.
The IP subnet-based VLAN entries are explained below.
Delete
To delete an IP subnet-based VLAN entry, check this box and click
Save
. The entry will be deleted
.from the switch
IP Address
Sets / shows the IP address. Enter a valid IP address in dotted decimal notation (‘x.y.z.w’) where x, y,
and z are decimal numbers from
0
to
255
. The default IP address of 0.0.0.0 is not valid.
Mask Length
Sets / shows the network mask length. The valid mask length range is
1
-
32
.
VLAN ID
Sets / shows the VLAN ID. The VLAN ID can be changed for the existing entries.
Port Members
Displays a row of check boxes for each port for each IP subnet-based VLAN entry. To include a port
in a IP subnet-based VLAN, check the checkbox. To remove or exclude the port from the IP subnet-
based VLAN, make sure the box is unchecked. By default, no ports are members, and all boxes are
unchecked. At least one port member must be checked in order to save an entry.
Add New Entry (Add a New IP Subnet-based VLAN)
Click the
Add New Entry
button to add a new IP subnet to VLAN ID mapping entry. An empty row is
added to the table, and the mapping can be configured as needed. Any IP address/mask can be
configured for the mapping. Legal values for the VLAN ID are
1
to
4095
.
