DESCRIPTION

Active

Check this box to activate this subnet based VLANs on the Switch.

 

 

DHCP-Vlan

When DHCP snooping is enabled DHCP clients can renew their IP address through

Overridethe DHCP VLAN or via another DHCP server on the subnet based VLAN.

 

Select this checkbox to force the DHCP clients in this IP subnet to obtain their IP

 

addresses through the DHCP VLAN.

 

 

Apply

Click Apply to save your changes to the Switch’s run-time memory. The Switch loses

 

these changes if it is turned off or loses power, so use the Save link on the top

 

navigation panel to save your changes to the non-volatile memory when you are

 

done configuring.

 

 

Active

Check this box to activate the IP subnet VLAN you are creating or editing.

 

 

Name

Enter up to 32 alphanumeric characters to identify this subnet based VLAN.

 

 

IP

Enter the IP address of the subnet for which you want to configure this subnet based

 

VLAN.

 

 

Mask-Bits

Enter the bit number of the subnet mask. To find the bit number, convert the subnet

 

mask to binary format and add all the 1’s together. Take “255.255.255.0” for

 

example. 255 converts to eight 1s in binary. There are three 255s, so add three

 

eights together and you get the bit number (24).

 

 

VID

Enter the ID of a VLAN with which the untagged frames from the IP subnet specified

 

in this subnet based VLAN are tagged. This must be an existing VLAN which you

 

defined in the Advanced Applications > VLAN screens.

 

 

Priority

Select the priority level that the Switch assigns to frames belonging to this VLAN.
