Chapter 10 VLAN Note: Subnet based VLAN applies to un-tagged packets and is applicable only when you use IEEE 802.1Q tagged VLAN. Figure 78 Advanced Application > VLAN > VLAN Port Setting > Subnet Based VLAN The following table describes the labels in this screen. Table 53 Advanced Application > VLAN > VLAN Port Setting > Subnet Based VLAN Setup LABEL Active DHCP-Vlan Override Apply Active Name IP Type IP Mask-Bits VID Priority DESCRIPTION Check this box to activate this subnet based VLANs on the Switch. 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. 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. Check this box to activate the IP subnet VLAN you are creating or editing. Enter up to 32 alpha numeric characters to identify this subnet based VLAN. Select to configure an IPv4 or IPv6 address. Enter the IPv4 or IPv6 address of the subnet for which you want to configure this subnet based VLAN. 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). 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 Application > VLAN screens. Select the priority level that the Switch assigns to frames belonging to this VLAN. 140 VES1724-56 User's Guide
