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 Ports 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: 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 Summary 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 Summary table
The Port Errors for Port Number abc and Channel xyz Summary
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 10 Gigabit Ports Control Attributes help
panel.
