LABEL DESCRIPTION
Active Check this box to activate this subnet based VLANs on the Switch.
DHCP-Vlan
Override When DHCP snooping is enabled DHCP clients can renew their IP address
through the 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).
