Displays: o Device socket counters o Current settings from the running communications software (A device socket is composed of two parts: the Internet device (interface) and the socket.) Format SHOW DEVICE_SOCKET [ device_socket ] [ /CONTINUOUS[=n] ] [ /FULL ] [ /HOST=host ] [ /[NO]LOCAL ] [ /PORT=n ] [ /SERVICE=service ] [ /TYPE=socket_type ]
1 – Parameters
device_socket Optional. Default: All device sockets. Device socket for which you want information. Specify the characters BG and the device's unit number, for example, BG3, BG17.
2 – Qualifiers
2.1 /CONTINUOUS
/CONTINUOUS[=n] Optional. Default: Static display; /CONTINUOUS=4. Automatically updates the display. Screen update interval in seconds. Valid only for a specific device socket. To terminate the display, press Ctrl/C.
2.2 /FULL
Optional. The default is to give a brief listing of the information. Displays complete information, including: o Application option settings, for example, ACCEPT or FULL_ DUPLEX_CLOSE o State of the service o Counters for receiving and sending buffers
2.3 /HOST
/HOST=host Optional. Default: All hosts. Displays information for device sockets bound to the specified host. This does not include device sockets bound to the "ANY host" (address 0.0.0.0).
2.4 /LOCAL
/LOCAL /NOLOCAL Optional. Default: /LOCAL. Displays information for device sockets bound to hosts in the local hosts database. /NOLOCAL: Displays information for device sockets bound to hosts in the hosts database and hosts known by the BIND resolver.
2.5 /PORT
/PORT=n Optional. Default: All local ports. Displays information for device sockets bound to the specified local port.
2.6 /SERVICE
/SERVICE=service Optional. Default: All services. Displays information for device sockets used for the specified service. To specify a lowercase or mixed-case service name, enclose it in quotation marks.
2.7 /TYPE
/TYPE=socket_type Optional. Default: /TYPE=ALL. Displays information for the specified type of device socket. Specify one of the following: o STREAM o DGRAM
3 – Examples
1.TCPIP> SHOW DEVICE_SOCKET BG21 /FULL Displays complete information about device socket BG21, including the options that are set, for example, the FULL_ DUPLEX_CLOSE option. (With the FULL_DUPLEX_CLOSE option set, the first data transmission on a TCP connection that has been closed by the remote application returns an EPIPE error. Subsequent send operations on the half-closed socket proceed normally.) The following table describes the counters in the first column of the display. Counter Meaning Q0LEN Number of sockets that are about to be connected to the specified socket QLEN Number of sockets that have established a connection but have not yet been accepted by the specified socket QLIMIT Number of sockets for the Q0LEN and QLEN sockets TIMEO Not used ERROR Error code temporarily stored on the socket OOBMARK Out-of-band mark 2.TCPIP> SHOW DEVICE_SOCKET BG75 /CONTINUOUS=10 Displays information about device socket BG75 every 10 seconds. 3.TCPIP> SHOW DEVICE_SOCKET /HOST="lark" Displays information about all device sockets for remote host lark. 4.TCPIP> SHOW DEVICE_SOCKET BG1898 Port Remote Device_socket Type Local Remote Service Host bg1898 STREAM 23 2568 TELNET 16.20.176.227 Displays socket type, service, and host information for device BG1898.
