1 SHOW 2 CHANNEL Displays PEDRIVER channel information for specific nodes. Each channel is a single NISCA communications path between a LAN device on a local system and a LAN device on a remote system. Use the SHOW CHANNEL command to display node names and local and remote device names. Format SHOW CHANNEL nodename 3 Parameters nodename[,nodename1,nodename2,...] Includes channels to specific nodes, which you can specify using wildcards. Each node name can be accompanied by optional qualifiers to specify local and remote device names. If no local or remote device name is specified, all channels associated with the specified node name are included. 3 Qualifiers /ALL Includes all channel data. /COUNTERS Includes channel counters data. /ECS /ECS (/NOECS) Includes only channels that are (or are not) members of the ECS. /EXCLUDE /EXCLUDE[,nodename1,nodename2,...] Excludes channels to specific nodes, which you can specify using wildcards. Each node name can be accompanied by optional qualifiers to specify local and remote device names. If no local or remote device name is specified, all channels associated with the specified node are included. /INTERVAL For the /COUNTERS display, displays the changes to counters since the last SHOW command. /LOCAL_DEVICE /LOCAL_DEVICE[=(landevicename1,landevice2,...)] Includes specific LAN devices that identify the local end of the channel; you can use wildcards to specify LAN devices. Use the SHOW LAN_DEVICE command to display device names. /n Displays the nth page. To select a particular page of a multi- page display, specify the number of the page you want to display. /OUTPUT /OUTPUT[=filespec] Creates the specified file and directs output to it. /REMOTE_DEVICE /REMOTE_DEVICE[=(landevicename1,landevice2,...)] Includes specific LAN devices that identify the remote end of the channel; you can use wildcards to specify LAN devices. Use the SHOW LAN_DEVICE command to display device names. /SDA Includes channel data displayed in SDA format, with all the data collected in one display for one channel. /SUMMARY Includes channel summary data. This is the default if /ALL, /COUNTERS, and /SDA qualifiers are not specified. 3 Examples 1.SCACP> SHOW CHANNEL NODE20/LOCAL=EWA The command in this example displays channel definition data for all nodes defined with local device EWA and any remote device and remote node name starting with NODE20. 2.SCACP> SHOW CHANNEL/COUNTERS/INTERVAL SCACP> SPAWN WAIT 0:0:10 SCACP> SHOW CHANNEL/COUNTERS/INTERVAL The first command in this example displays channel counters since the last SHOW command. The SPAWN command tells the DCL WAIT command to insert a 10-second delay. The second SHOW CHANNEL command displays counters after the 10-second period. 3.SCACP> SHOW CHANNEL/1/3 The command in this example displays the first and third pages of data for all channels. The first page contains Channel Summary data, and the third page contains Channel Equivalent Channel Set (ECS) data. 2 DEFAULT_PORT Displays the current default port. Format SHOW DEFAULT_PORT 3 Parameters None 3 Qualifiers /OUTPUT /OUTPUT[=filespec] Creates the specified file and directs output to it. 3 Example SCACP> SHOW DEFAULT_PORT The command in this example displays the currently selected port, PEA0, which indicates PEDRIVER. 2 LAN_DEVICE Displays PEDRIVER device data. Each device is a local LAN device on the system, which can be used for NISCA communications. Format SHOW LAN_DEVICE landevicename 3 Parameters landevicename[,landevice1,landevice2,...] Includes specific LAN devices, which you can specify using wildcards. Use the /EXCLUDE qualifier to exclude LAN devices. Use the SHOW LAN_DEVICE command to display device names. 3 Qualifiers /ALL Includes all device data. /COUNTERS Includes device counters data maintained by PEDRIVER and counters data maintained by the LAN drivers. /INTERVAL For the /COUNTERS display, displays the changes to counters since the last SHOW command. /n Displays the nth page. To select a particular page of a multi- page display, specify the number of the page you want to display. /OUTPUT /OUTPUT[=filespec] Creates the specified file and directs output to it. /SDA Includes LAN device data displayed in SDA format, with all the data collected in one display for one LAN device. /SUMMARY Includes device summary data. This is the default if /ALL, /COUNTERS, and /SDA qualifiers are not specified. 3 Examples 1.SCACP> SHOW LAN_DEVICE/COUNTERS The command in this example displays device counters. 2.SCACP> SHOW LAN_DEVICE/COUNTERS/INTERVAL SCACP> SPAWN WAIT 0:0:10 SCACP> SHOW LAN_DEVICE/COUNTERS/INTERVAL The first command in this example displays device counters since the last SHOW command. The SPAWN command tells the DCL WAIT command to insert a 10-second delay. The second SHOW command displays counters after the 10-second period. 2 TRACE Displays PEDRIVER tracing data and parameters. NOTE This command is reserved for use by Compaq Services and OpenVMS Engineering only. Trace commands and output are subject to change from release to release. Format SHOW TRACE nodename 3 Parameters nodename[,nodename1,nodename2,...] Includes channels to specific nodes, which you can specify using wildcards. Each node name can be accompanied by optional qualifiers to specify local and remote device names. If no local or remote device name is specified, all channels associated with the specified node are included. Use the SHOW CHANNEL command to display node names and local and remote device names. 3 Qualifiers /CONTEXT Displays only PEDRIVER trace settings and the event definition. If this qualifier is not included, trace event data is displayed. /EVENT /EVENT[=(event1,event2,...)] Enables tracing on specific events, which you can specify using wildcards. The default is all of the events that are in the trace buffer. Use the SHOW TRACE/CONTEXT command to display event names. /EXCLUDE /EXCLUDE[=(nodename1,nodename2,...)] Excludes channels to specific nodes, which you can specify using wildcards. Each node name can be accompanied by optional qualifiers to specify local and remote device names. If no local or remote device name is specified, all channels associated with the specified node are included. /GLOBAL /GLOBAL (default when no nodes are specified) /NOGLOBAL (default when nodes are specified) Specifies whether global trace data is to be returned. /INPUT /INPUT[=filename] Reads trace data from the specified file and displays it. /LOCAL_DEVICE /LOCAL_DEVICE[=(landevicename1,landevice2,...)] Includes specific LAN devices that identify the local end of the channel; you can use wildcards to specify LAN devices. Use the SHOW LAN_DEVICE command to display device names. /OUTPUT /OUTPUT[=filename] Creates the specified file and directs output to it. If the filename extension is .DMP, the trace data is written to a dump file so that you can use the /INPUT qualifier to display it later. /REMOTE_DEVICE /REMOTE_DEVICE[=(landevicename1,landevice2,...)] Includes specific LAN devices which identify the remote end of the channel, which you can specify using wildcards. Use the SHOW LAN_DEVICE command to display device names. /SORT /SORT /NOSORT (default) Returns trace data sorted across channels, VCs, and the global trace buffer by sequence number. The default is trace data returned for channels and VCs one at a time, in order, for the channel or VC, but not across channels and VCs. 3 Examples 1.SCACP> SHOW TRACE/CONTEXT The command in this example displays trace settings and definition. 2.SCACP> SHOW TRACE/OUTPUT=NODE10.TRC The command in this example displays trace data and writes it to the specified file. An example of the screen output of a SHOW TRACE/CONTEXT command follows.

Each VC is an SCACP communications path between the local system and a remote system comprised of a set of channels. Use the SHOW CHANNEL or SHOW VC commands to display node names, which are simply the names of the remote nodes. Format SHOW VC nodename 3 Parameters nodename[,nodename1,nodename2,...] Includes specific nodes, which you can specify using wildcards. 3 Qualifiers /ALL Includes all VC data. /COUNTERS Includes VC counter data. /EXCLUDE /EXCLUDE[=(nodename1,nodename2,...)] Excludes specific nodes, which you can specify using wildcards. Use the SHOW CHANNEL or SHOW VC commands to display VC names, which are simply the names of the remote nodes. /INTERVAL For the /COUNTERS display, displays the changes to counters since the last SHOW command. /n Displays the nth page. To select a particular page of a multi- page display, specify the number of the page you want to display. /OUTPUT /OUTPUT[=filespec] Creates the specified file and directs output to it. /SDA Includes VC data displayed in SDA format. /SUMMARY Includes VC summary data. This is the default if /ALL, /COUNTERS, and /SDA qualifiers are not specified. 3 Examples 1.SCACP> SHOW VC/COUNTERS NODE10 The command in this example displays VC counters for all VCs whose name (remote node name) starts with NODE10. 2.SCACP> SHOW VC/COUNTERS/INTERVAL SCACP> SPAWN WAIT 0:0:10 SCACP> SHOW VC/COUNTERS/INTERVAL The first command in this example displays VC counters since the last SHOW command. The SPAWN command tells the DCL WAIT command to insert a 10-second delay. The second SHOW VC command displays counters after the 10-second period.
