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 Port 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.
- Port Control for Port Number abc
and Channel xyz Table: Provides the OSA-Express3
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 Control for Port Number abc and Channel xyz table
provides OSA-Express3 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 Express3 Ports Control Attributes help panel.
