Article Summary

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 ▶Configuration ▶Traffic ▶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 ▶Configuration ▶Traffic ▶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 ▶Configuration ▶Traffic ▶Mode)

ParameterDescription
S-VLAN EthertypeThis 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 EthertypeThis 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)

ParameterDescription
MTR StateEnable/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.
