OSA-Express3 Port Control Workspace
The OSA-Express3 Port Control workspace displays control data
for the OSA-Express3 Ethernet adapters. The OSA-Express3 Port Control
workspace is accessed only as a drill down from the OSA-Express3 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-Express3 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 osaexp3gigabitEthernet,
osaexp3oneThousandBaseTEthernet, or osaexp3tenGigabitEthernet, right-click
the Link icon by this table row.
- A conditional link is displayed in the list of available links.
Select OSA-Express3 Ports to display the OSA-Express3 Ports Summary workspace.
- Right-click on the Link icon by one
of the rows in the Ports Summary for Channel xyz Summary
Table and select OSA-Express3 Port Control.
The OSA-Express3 Port Control workspace contains the following
views:
- 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-Express3 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-Express3 Ports
Summary workspace.
