DESCRIPTION

Active

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

 

 

DHCP-Vlan

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

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

 

Select this 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

Select this 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.

 

 

Add

Click Add 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.

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
