OSA 10 Gigabit Ports Control Attributes

Use the OSA 10 Gigabit Ports Control attributes to monitor the data associated with a port on an OSA-Express2 10 Gigabit Ethernet feature.

Transmitter on (XON) and transmitter off (XOFF) 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, and are of particular interest if the port is at 100% utilization.

Channel Number The channel path identifier (CHPID) corresponding to this device. The format is a string of two hexadecimal characters.

Collection Time The time and date of the data sampling. This time is displayed in the following format:

mm/dd/yy hh:mm:ss

Where:

The stored format is a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:

Host Name The host name of the TCP/IP stack. The format is an alphanumeric string no longer than 255 characters.

Origin Node The unique identifier for the TCP/IP stack being displayed. The format is an alphanumeric string no longer than 32 characters.

Pause MAC Packets Received The number of valid Pause MAC control packets received by the OSA during the most recent time interval. The format is an unsigned integer.

Pause MAC Packets Transmitted The number of valid Pause MAC control packets transmitted by the OSA during the most recent time interval. The format is an unsigned integer.

Port Name The name of the port as specified by the VTAM Transport Resource List Entry (TRLE). The format is a 16-character alphanumeric string.

Port Number The physical port number for this port. Currently, this value can be only zero (0). The format is an integer.

System ID The SMF system ID. The format is an alphanumeric string no longer than 4 characters.

TCPIP STC Name The name of the TCP/IP job. The format is an alphanumeric string no longer than 8 characters.

Total Pause MAC Packets Received The number of valid Pause MAC control packets received by the OSA since the last time the OSA port was reset. The format is an unsigned integer.

Total Pause MAC Packets Transmitted The number of valid Pause MAC control packets transmitted by the OSA since the last time the OSA port was reset. The format is an unsigned integer.

Total XOFF Packets Received The number of XOFF (Transmitter OFF) packets received by the OSA since the last time the OSA port was reset. XOFF packets can use the global address or the station address. Receiving XOFF packets indicates that the sender experienced a problem with a queue filling up or some other software-initiated action. The format is an unsigned integer.

Total XOFF Packets Transmitted The number of XOFF (Transmitter OFF) packets transmitted by the OSA since the last time the OSA port was reset. Sending XOFF packets indicates that the queue is filling up or some software-initiated action has occurred. The format is an unsigned integer.

Total XON Packets Received The number of XON (Transmitter ON) packets received by the OSA since the last time the OSA port was reset. XON packets can use the global address or the station address. Receiving XON packets indicates that the sender experienced a problem with a queue filling up or some other software-initiated action. The format is an unsigned integer.

Total XON Packets Transmitted The number of XON (Transmitter ON) packets transmitted by the OSA since the last time the OSA port was reset. Sending XON packets indicates that the queue is filling up or some software-initiated action has occurred. The format is an unsigned integer.

Trap Control Flags The value of this object determines which traps will be generated by the OSA. The value of this object is initially all zeros, indicating that all traps will be sent to the OSA subagent. Setting the appropriate bit prevents a particular trap from being sent to the subagent. When the bit value of the disableEthLANChange bit is set to zero (0), then the trap ibmOSAExp10GigEthLANStateChange is sent. The format is a 4-digit hexadecimal number. Valid values are:

XOFF Packets Received The number of XOFF (Transmitter OFF) packets received by the OSA during the most recent time interval. XOFF packets can use the global address or the station address. Sending XOFF packets indicates that the sender experienced a problem with a queue filling up or some other software-initiated action. The format is an unsigned integer.

XOFF Packets Transmitted The number of XOFF (Transmitter OFF) packets transmitted by the OSA during the most recent time interval. Sending XOFF packets indicates that the queue is filling up or some software-initiated action has occurred. The format is an unsigned integer.

XON Packets Received The number of XON (Transmitter ON) packets received by the OSA during the most recent time interval. XON packets can use the global address or the station address. Receiving XON packets indicates that the sender experienced a problem with a queue filling up or some other software-initiated action. The format is an unsigned integer.

XON Packets Transmitted The number of XON (Transmitter ON) packets transmitted by the OSA during the most recent time interval. Sending XON packets indicates that the queue is filling up or some software-initiated action has occurred. The format is an unsigned integer.
