SHOW 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
Parameter
nodename[,...]
Includes channels to specific nodes, which you can use wildcards to
specify. 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.
Qualifiers
/ALL
Includes all channel data.
/COUNTERS
Includes channel counters data.
/ECS
/NOECS
Includes only channels that are (or are not) members of the ECS.
/EXCLUDE=(nodename[,...])
Excludes channels to specific nodes, which you can use wildcards to
specify. 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=(landevicename[,...])
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
multipage display, specify the number of the page you want to display.
/OUTPUT=filespec
Creates the specified file and directs output to it.
/REMOTE_DEVICE=(landevicename[,...])
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.
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.
SHOW CIRCUIT
Displays SCA circuit information. You can further qualify each node
name you specify with additional parameters to uniquely identify a
single circuit.
Format
SHOW CIRCUIT nodename
Parameter
nodename[,...]
Includes specific circuits to individual nodes, which you can use
wildcards to specify.
Qualifiers
/EXCLUDE=(nodename[/PORT=portname[/RSTATION=n]][,...])
Allows you to exclude a specific circuit to a node. If multiple
circuits to the same node exist, you can use the /PORT and /RSTATION
qualifiers to uniquely identify the circuit.
/PORT=portname[/RSTATION=n]
If multiple circuits to the same node exist, you can use the /PORT and
/RSTATION qualifiers to uniquely identify the circuit. You can use the
/RSTATION qualifier only in conjunction with the /PORT qualifier.
Example
The command in this example displays all circuits to nodes over port
PEA0.
