Use these attributes to view TCP/IP connections.
Address Space ID The MVS address space ID of the address space that opened the socket. This is a 4-digit hexadecimal number.
AT-TLS Cipher The negotiated cipher that is used by the secure connection. This value, which is shown as a hexadecimal code, applies only if AT-TLS Connection Status has a value of Secure. For valid values, see information about the TTLSCipherParms statement in the z/OS Communications Server: IP Configuration Reference.
AT-TLS Connection Status The current application transparent transport layer security (AT-TLS) policy status for the connection. The following values are valid:
AT-TLS Partner Userid The user ID associated with the certificate of the partner. This value is applicable only if AT-TLS Connection Status has a value of Secure and a user ID is associated with the certificate of the partner.
AT-TLS Policy Status The AT-TLS status for the connection. The following values are valid:
AT-TLS Security Type The type of system SSL secure session defined in the AT-TLS policy that is used by the connection. The following values are valid:
AT-TLS SSL Protocol The negotiated SSL protocol in use by the connection. The following values are valid:
Byte Rate The number of bytes sent or received per minute during the most recent time interval.
Bytes Received The number of bytes received during the most recent time interval.
Bytes Sent The number of bytes sent during the most recent time interval.
Bytes Sent or Received The number of bytes sent or received during the most recent time interval.
Collection Time The date and time of the data sampling. By default, this value is displayed as MM/DD/YY hh:mm:ss, where MM is the month, DD is the day, YY is the year, hh is the hour, mm is the minute, and ss is the second.
Connection ID The hexadecimal representation of the connection number.
Connection Start Time The date and time that the connection started. By default, this value is displayed as MM/DD/YY hh:mm:ss, where MM is the month, DD is the day, YY is the year, hh is the hour, mm is the minute, and ss is the second.
Connection State The state of the connection. The following values are valid:
Current Send Window Size The current size of the send window.
Interface Name The name of the interface.
Last Activity Remote Timestamp The most recent time stamp value, in milliseconds, received from the remote side of the connection. If the TCP time stamp header option is not used, the value of this field is zero. If the TCP time stamp header option is used, this field contains bits 10 - 41 of a related time stamp that is provided by z/OS Communications Server. The related time stamp is in store clock (STCK) format, which approximately indicates units of seconds. To convert this field into a STCK value and then into a date and time, follow these steps:
Last Activity Timestamp The date and time of the last activity on this connection. By default, this value is displayed as MM/DD/YY hh:mm:ss, where MM is the month, DD is the day, YY is the year, hh is the hour, mm is the minute, and ss is the second.
Last Timestamp Age The time, in milliseconds, when the most recent time stamp from the partner was updated. If the TCP time stamp header option is not used, the value of this field is zero. If the TCP time stamp header option is used, this field contains bits 10 - 41 of a related time stamp that is provided by z/OS Communications Server. The related time stamp is in store clock (STCK) format, which approximately indicates units of seconds. To convert this field into a STCK value and then into a date and time, follow these steps:
Local IP Address The local IP address for this TCP connection. IPv4 and IPv6 addresses can be displayed.
Local Port The local port for this TCP connection.
Max Send Window Size The maximum size of the send window.
Number of Duplicate ACKs The number of duplicate ACKs received for this connection.
Origin Node The parent node of the workspace.
Passive or Active Open The type of open performed. The following values are valid:
Percent Segments Retransmitted The percent of TCP segments that were retransmitted over this connection since the connection started.
Remote IP Address The remote IP address for this TCP connection. IPv4 and IPv6 addresses can be displayed.
Remote Port The remote port for this TCP connection.
Resource Name The text identification of the resource. This value represents the user who opened the socket. It is updated during bind processing.
Segments Received The number of segments received over this connection during the most recent time interval.
Segments Retransmitted The number of segments retransmitted over this connection during the most recent time interval.
Segments Sent The number of segments sent over this connection during the most recent time interval.
Segments Sent or Received The number of segments sent or received over this connection during the most recent time interval.
Sysplex Name The name of the sysplex.
TCB Address The address of the TCB in the address space that opened the socket.
TCPIP Host Name The short TCP/IP host name.
TCPIP Job Name The TCP/IP job name.
Telnet APPL Name The target VTAM application name if the TCP connection is for a TN3270 or TN3270E session.
Telnet Logmode The VTAM logmode if the TCP connection is for a TN3270 or TN3270E session.
Telnet LU Name The VTAM LU name if the TCP connection is for a TN3270 or TN3270E session.
Telnet Protocol The telnet mode. Valid values are TN3270, TN3270E, LINEMODE, and N/A.
Telnet User Client Name The user ID of the client if the TCP connection is for a TN3270 or TN3270E session.
Total Bytes The total number of bytes sent and received for this connection since the connection started.
Total Bytes Received The total number of bytes received from IP for this connection since the connection started.
Total Bytes Sent The total number of bytes sent to IP for this connection since the connection started.
Total Segments The total number of segments sent and received for this connection since the connection started.
Total Segments Received The total number of segments received from IP for this connection since the connection started.
Total Segments Retransmitted The total number of segments retransmitted over this connection since the connection started.
Total Segments Sent The total number of segments sent to IP for this connection since the connection started.
