This example of the SHOW POOL/SUMMARY command displays an allocation summary for each region of pool.

SHOW PORTS

Displays those portions of the port descriptor table (PDT) that are port independent.

Format

SHOW PORTS [/qualifier[,...]]


Parameters

None.

Qualifiers

/ADDRESS=pdt-address

Displays the specified port descriptor table (PDT).10

/BUS[=bus-address]

Displays BUS (LAN device) structure data.

/CHANNEL[=channel-address]

Displays channel (CH) data.

/DEVICE

Displays the network path description for a channel.

/MESSAGE

Displays the message data associated with a virtual circuit (VC).

/NODE=name

Displays virtual circuit (VC) information associated with the named node on the specified PDT. You must use this qualifier with /ADDRESS qualifier.

/VC[=vc-address]

Displays the virtual circuit data.

Description

The SHOW PORTS command provides port-independent information from the port descriptor table (PDT) for those CI ports with full SCS connections. This information is used by all system communications services (SCS) port drivers.

Note that the SHOW PORTS command does not display similar information about UDA ports, BDA ports, and similar controllers.

The SHOW PORTS command also defines symbols for PEDRIVER based on the cluster configuration. These symbols include the following information:

The following symbols are defined automatically:
Symbol Explanation or Example
VC_nodename VC_NODE1, address of the local node's virtual circuit to node NODE1
CH_nodename The preferred channel for the virtual circuit; for example, CH_NODE1, address of the local node's preferred channel to node NODE1
BUS_busname BUS_ETA, address of the local node's BUS structure associated with LAN adapter ETA0
PE_PDT Address of PEDRIVER's port descriptor table
MGMT_VCRP_busname MGMT_VCRP_ETA, address of the management VCRP for BUS ETA
HELLO_VCRP_busname HELLO_VCRP_ETA, address of the HELLO message VCRP for BUS ETA
VCIB_busname VCIB_ETA, address of the VCIB for BUS ETA
UCB_LAVC_busname UCB_LAVC_ETA, address of the LAN device's UCB used for the local area VAXcluster protocol
UCB0_LAVC_busname UCB0_LAVC_ETA, address of the LAN device's template UCB
LDC_LAVC_busname LDC_LAVC_ETA, address of the LDC structure associated with LAN device ETA
LSB_LAVC_busname LSB_LAVC_ETA, address of the LSB structure associated with LAN device ETA

These symbols equate to system addresses for the corresponding data structures. You can use these symbols, or an address, after the equal sign in SDA commands.

The SHOW PORTS command produces several displays. The initial display, the PDT summary page, lists the PDT address, port type, device name, and driver name for each PDT. Subsequent displays provide information taken from each PDT listed on the summary page.

You can use the /ADDRESS qualifier of the SHOW PORTS command to produce more detailed information about a specific port. The first display of the SHOW PORTS/ADDRESS command duplicates the last display of the SHOW PORTS command, listing information stored in the port's PDT. Subsequent displays list information about the port blocks and virtual circuits associated with the port.

The SHOW PORTS/BUS=BUS_id command displays the data for the specified BUS structure. The last event time is at the top of the lower right-hand column. If an error was counted, the last error time is displayed under Xmt Errors. The normal status is: RUN, ONLINE, and RESTART.

The Xmt Error field indicates a problem detected during transmission of a message. The error rate should be less than one per hour.

The SHOW PORTS/VC=VC_id command displays the virtual circuit data for the specified remote node and a channel summary. In this display, the upper center of the display contains the virtual circuit status. The lower right-hand corner contains the virtual circuit open and close times.

The ReXmt field indicates a problem sending messages to the remote system. The error rate per hour should be less than the Pipe Quota field.

The ReRcv field indicates a problem receiving messages from the remote system. The error rate per hour should be less than the Pipe Quota field.

This display is useful after the local area VAXcluster network failure analysis data has been loaded. After a network failure analysis, this display indicates primary and secondary failed component suspects in the following ways:

#7

SDA> SHOW PORTS /DEVICE /CHANNEL=address
      

This SHOW PORTS command displays the channel data and the network path description if it was provided by the network failure analysis.

#8

SDA> SHOW PORTS/BUS/CHANNEL/DEVICE/MESSAGE/VC/ADDRESS=PE_PDT 
      

This command displays all of the bus structures, all of the virtual circuits and their message counters, and channels, including network path descriptions when available.

The command in this example displays virtual connect information associated with the DAVID3 node, which is associated with the port descriptor table whose address is 862C8D80.

Note

10 You can find the pdt-address for any active connection on the system in the PDT summary page display of the SHOW PORTS command. This command also defines the symbol PE_PDT. CDT addresses are also stored in many individual data structures related to SCS connections; for instance, in the path block displays of the SHOW CLUSTER/SCS command.
