Defining Interfaces

The Interface definition specifies an interface device name, its flow direction, and the bandwidth to be associated with it.

Figure 5-1 Interfaces Window

The Interface List in the left hand column displays all the currently configured interface device names. To display configuration information for an interface, click its name. The relevant parameters and values are displayed in the interface panel.

The configurable parameters are:

• Device Name.

  A new interface is created with the temporary name new. To change this name, type a new name in the Device Name field and click Apply. The device name must follow the Solaris convention of driver name, driver number. For example qe0.

  The Device Name is automatically appended with _in or _out depending on the flow direction selected.

• Bandwidth.

  This is the operating bandwidth rate associated with the device, in bits per second. This value need not necessarily be the maximum of which the device is capable. The value should not exceed the device's maximum.

  ---

  Note -

  Consider the actual operating rate of the device, rather than the nominal rate when determining the value of the bandwidth rate.

• Default Class.

  Allowed values are:

  Yes	Create a default class.
  No	There is no default class.

• Flow Direction.

  Allowed values are:

  In	The hierarchy below this interface will regulate incoming traffic only.
  Out	The hierarchy below this interface will regulate outgoing traffic only.

  Depending on your selection, the interface device name is automatically appended with _in or _out.

• IP Transparency Mode.

  Allowed values are:

  Yes	Use Solaris Bandwidth Manager in IP-transparent mode.
  No	Use Solaris Bandwidth Manager in Non-transparent mode.

  If you choose to run Solaris Bandwidth Manager in IP-transparent Mode, you must complete the additional options in the panel below:

  • Network Device.

    This is the name of the device used to communicate with the network, as opposed to the router.

  • Router Address

    This a list of IP addresses (or hostname) of the router. If you specify more than one address, separate them with a comma.

  • Multicast

    The Mulicast option defines how multicast packets are forwarded:

    None	No multicast packets are forwarded.
    All	All multicast packets are forwarded through ipqos with the exception of: packets where the time-to live is less than 2 packets for the local subnet, with destination addresses in the range 224.0.0.0 to 224.0.0.255 In both of these cases, they go directly to the router.
    Direct	All multicast packets are forwarded directly, not through ipqos.

  • Router MAC

    This is the MAC address of the router which can be expressed in the standard hexadecimal format.

  • SendNon-IP traffic to:

    This option defines how non-IP packets are forwarded:

    scheduler	All non-IP packets are classified and scheduled
    router	All non-IP packets are forwarded directly, not through ipqos. These packets are not logged in the flow statistics

• Statistics Logging.

  Allowed values are:

  statistics	Statistics are collected on the interface, with the classifier running but not the scheduler.
  statistics and TOS	Statistics are collected on the interface, with the Type of Service activated and the classifier running, but not the scheduler.
  statistics and TOS and scheduler	Statistics are collected on the interface, with the classifier and scheduler running.

You can also use the Interface window to disable Solaris Bandwidth Manager. Select No in the Active panel.
