OSA-Express2 10 Gigabit Port Control Workspace
The OSA-Express2 10 Gigabit Port Control workspace displays control data
for the OSA-Express2 10 Gigabit Ethernet adapters. The OSA-Express2 10 Gigabit
Port Control workspace is accessed only as a drill down from the OSA-Express2
10 Gigabit Ports Summary workspace using Channel Number and Port Number as
link attributes.
Transmitter ON (XON), transmitter OFF (XOFF), and Pause MAC packets are
flow control packets between the OSA and the switch to which it is connected.
They are used to provide flow control between the two ports. These attributes
are of particular interest when the port is at 100% utilization.
To display the OSA-Express2 10 Gigabit Port Control workspace, do the following:
- Click the OSA navigator item for a specific TCP/IP
stack to display the OSA Channels workspace.
- If the value for the OSA channel Subtype attribute
in the OSA-Express Channels Summary Table is tenGigabitEthernet, right-click
the Link icon by this table row.
- A conditional link is displayed in the list of available links. Select OSA-Express2 10 Gigabit Ports to display the OSA-Express2
10 Gigabit Ports Summary workspace.
- Click the Link icon by one of the rows of the Port
Summary for Channel xyz summary table.
- Select OSA-Express2 10 Gigabit Port Control.
The OSA-Express2 10 Gigabit Port Control workspace contains the following
views:
- Current Pause MAC Packets: This bar chart displays
the number of pause MAC packets received or the pause MAC packets transmitted
by the specified port over the current collection interval. The information
is presented in a bar graph where:
- Yellow represents the number of pause MAC packets received over the current
collection period.
- Blue represents the number of pause MAC packets transmitted over the
current collection period.
This data applies to a port selected from the OSA-Express2 10 Gigabit
Ports Summary workspace.
- Current XOFF Packets: Displays the number of Transmitter
OFF (XOFF) packets received or the XOFF packets transmitted by the specified
port over the current collection interval. The information is presented in
a bar graph where:
- Yellow represents the number of XOFF packets received over the current
collection period.
- Blue represents the number of XOFF packets transmitted over the current
collection period.
This data applies to a port selected from the OSA-Express2 10 Gigabit
Ports Summary workspace.
- Current XON Packets: Displays the number of Transmitter
ON (XON) packets received or the XON packets transmitted by the specified
port over the current collection interval. The information is presented in
a bar graph where:
- Yellow represents the number of XON packets received over the current
collection period.
- Blue represents the number of XON packets transmitted over the current
collection period.
This data applies to a port selected from the OSA-Express2 10 Gigabit
Ports Summary workspace.
- Port Control for Port Number abc and
Channel xyz Table: Provides the OSA-Express2
10 Gigabit control data for the specific port and channel, where abc is
the selected port number link attribute and xyz is the selected channel
number link attribute.
Port Control for Port Number abc and
Channel xyz Table
The Port Errors for Port Number abc and Channel xyz table
provides OSA-Express2 10 Gigabit control data for the specified port number
and channel, where abc is the selected port number link attribute
and xyz is the selected channel number link attribute.
For a complete list of the attributes available in the Port Control for
Port Number abc and Channel xyz table, and a brief description
of each, see the OSA 10Gigabit Ports Control Attributes help panel.
