Commands for Configuring Rings
To configure the rings of a datalink, use the following dladm
subcommands:
-
# dladm show-linkprop link
Displays the current values of the datalink properties, including Rx and Tx
rings. For an example, see Example 72, Ring Use and Ring Assignments on a Datalink.
The following table describes the ring properties that are displayed by using
the dladm show-linkprop command.
|
|
|
|
rxringsavail
|
Read only
|
Indicates the number of Rx rings that you can allocate to
hardware-based clients on the physical datalink.
|
|
rxhwclntavail
|
Read only
|
Indicates the number of hardware-based Rx clients that you can
create on the physical datalink.
|
|
rxrings
|
Read and write
|
Indicates the number of Rx rings exclusively used by the
datalink. You can set this property to one of the three possible
values:
-
hw indicates that you are configuring a
hardware-based client. You can set this value, if the
hardware-based Rx clients (rxhwclntavail)
on the underlying physical link is greater than zero.
-
number
indicates the number of rings that you can assign to a
datalink. You can set this value, if the Rx rings
(rxringsavail) on the underlying
physical link is greater than zero.
-
sw indicates that the datalink is a
software-based client.
|
|
txringsavail
|
Read only
|
Indicates the number of Tx rings that you can allocate to
hardware-based clients on the physical datalink.
|
|
txhwclntavail
|
Read only
|
Indicates the number of hardware-based Tx clients that you can
create on the physical datalink.
|
|
txrings
|
Read and write
|
Indicates the number of Tx rings exclusively used by the
datalink. You can set this property to one of the three possible
values:
-
hw indicates that you are configuring a
hardware-based client. You can set this value, if the
hardware-based Tx clients (txhwclntavail)
on the underlying physical link is greater than zero.
-
number
indicates the number of rings that you can assign to a
datalink. You can set this value, if the Tx rings
(txringsavail) on the underlying
physical link is greater than zero.
-
sw indicates that the datalink is a
software-based client.

|
-
# dladm show-phys –H link
Displays how the rings of a physical datalink are currently being used
by existing clients.
-
# dladm create-vnic –p ring-properties –l link VNIC
- –p ring-properties
-
Refers to the ring-properties whose values can be set.
Creates a client with a specific number of Rx or Tx rings.
-
# dladm set-linkprop –p ring-properties VNIC
Allocates rings to a specific client, provided that the rings are available and
ring allocation is supported.
