Setting the S-VLAN Ethertype

The Ethertype value that is associated with the Service VLAN (S-VLAN) is set globally for the unit. The S-VLAN Ethertype options are:

  • 0x88A8: Most applications use this value
  • 0x9100: A supported legacy value

The S-VLAN value is typically left at the default of 0x88A8.

If you change the S-VLAN Ethertype value to 0x9100, the T-VLAN Ethertype value will automatically be switched to 0x88A8. All units in a given network that use the S-VLAN Ethertype must have the same assigned Ethertype value.

Tip: To avoid issues related to changing the S-VLAN value, consider assigning the appropriate value to the S-VLAN Ethertype before creating system elements that require a defined Ethertype, such as interfaces, filters and RFC-2544.

For more information on specific parameters, refer to the table "General System Settings (System â–¶Configuration â–¶Traffic â–¶Mode)".

Regulating Management Traffic

As with other traffic types, it can be useful to regulate management traffic.

To set up the management traffic regulation (MTR)

  1. Access the page System â–¶Configuration â–¶Traffic â–¶Mode.

  2. Enable the MTR State box.

  3. Complete the other parameters, then click Apply.

For more information on specific parameters, refer to the following table.

General System Settings (System â–¶Configuration â–¶Traffic â–¶Mode)

Parameter Description
S-VLAN Ethertype This value affects all elements that make use of the S-VLAN Ethertype, such as interfaces and filters.

Possible values are:

  • 0x88A8
  • 0x9100
Note: This value is typically left at the default of 0x88A8.
T-VLAN Ethertype This value appears here for your convenience; it is based on the value selected in the S-VLAN Ethertype drop-down list above.

Management Traffic Regulation (MTR)

Parameter Description
MTR State Enable/Disable the regulation of management traffic.
Rate (Kbps) The average data rate, expressed in kbps.
Latency (ms) The transmit queue size, expressed in milliseconds.
Burst (bytes) The maximum burst size, expressed in bytes.
