Add VLAN IP

This option adds VLAN filtering on the specified IP address.

  1. Enter the IP Address on which you want to add VLAN filtering.

    Valid Values: 32-bit value from 0-0xDFFFFFFF (representing IP addresses 0.0.0.0 - 223.255.255.255)

    Default Value: none

  2. Enter the Subnet Mask for the IP address you entered.

    Valid Values: 32-bit value from 0-0xFFFFFFFF (representing IP addresses 0.0.0.0 - 223.255.255.255)

    Default Value: none

  3. Select the Submit button.

  4. Select the Ports on which you want to configure the VLAN.

  5. Enter the Age (in minutes) of VLAN auto-Detection.

    This is the amount of time that an Auto-Detect port will remain in the forwarding state in the absence of traffic received from that port for this VLAN.

    Valid Values: 0 - 4294967295

    Default Value: 5000

  6. Click to Enable IP-Cut-Through from this VLAN.

    Answering yes will allow forwarding of IP traffic from devices on this VLAN to devices on other VLANs that have IP-Cut-Through reception enabled.

    IP-Cut-Through allows the establishment of data-direct VCCs between stations on different IP subnets. IP Cut-Through is applicable in subnetted IP networks only. If stations are on different IP nets, then data-direct VCCs cannot be established between them and a device must be used to forward traffic between those stations.

    To use IP-Cut-Through, the subnet mask in end-stations (typically just servers) should be shortened. That is, a 255.255.255.255 subnet mask is shortened to 255.255.255.0 to imply a 3-byte subnet and a 255.255.0.0 subnet mask implies a 2-byte subnet. Shortening the subnet mask will cause the end-station to ARP for the destination and establish a direct connection (VCC) to the destination (or intermediate LAN switch), maximizing network throughput. However, this configuration can produce the following side effects:

    1. A large number of ARP entries can be created in end-stations with a shortened mask which in turn can increase their CPU utilization. If these end-stations are ATM-attached, the number of ATM connections (data-direct VCCs) will also increase.

      Therefore, the need for faster network throughput must be balanced against increased CPU utilization in the end-stations and increased VCC utilization in the ATM switches.

    2. An end-station with a shortened mask could ARP for a destination that is not directly connected. For example, this can happen if the destination is on a different type of LAN or behind a device firewall. The only way to reach this destination is through a device but devices normally do not propagate ARPs between networks. To allow this scenario to work, the Proxy ARP function must be enabled in the device. This will cause the device to respond to the ARP and subsequent traffic will be sent to the device.

  7. Click to Enable IP-Cut-Through to this VLAN. Answering yes will allow IP traffic to be forwarded to devices on this VLAN from devices on other VLANs that have IP-Cut-Through transmission enabled.

  8. Click to Track active MAC addresses on this VLAN.

    Answering yes causes source MAC addresses from transmissions on this VLAN to be saved. Learned addresses will be aged out with the aging timer for this VLAN.
