CMPC, CMPC+ and CSNA Commands

Syntax Description

path	Hexadecimal value in the range 0000 to FFFF. This value specifies the logical channel path and consists of two digits for the physical connection (either on the host or on the ESCON director), one digit for the channel logical address, and one digit for the control unit logical address. If the path is not specified in the IOCP, the default values for channel logical address and control unit logical address is 0.
device	Hexadecimal value in the range of 00 to FF. This is the unit address associated with the control unit number and path as specified in the host IOCP file.
tg-name	Name of the CMPC or CMPC+ transmission group. The maximum length of the name is 8 characters.
read	Same read value as specified in the TRL major node.
write	Same write value as specified in the TRL major node.

Syntax Description

path	Hexadecimal value in the range 0000 to FFFF. This value specifies the logical channel path and consists of two digits for the physical connection (either on the host or on the ESCON director), one digit for the channel logical address, and one digit for the control unit logical address. If the path is not specified in the IOCP, the default values for channel logical address and control unit logical address is 0.
device	Hexadecimal value in the range 00 to FF. This is the unit address associated with the control unit number and path as specified in the host IOCP file.
maxpiu value	(Optional) Maximum channel I/O block size in bytes that is transmitted across the physical channel from the CMCC adapter to the attached mainframe. The range is 4096 to 65535 bytes. The default is 20470 bytes.
time-delay value	(Optional) Number of milliseconds a host-bound SNA frame may be delayed in order to maximize the channel I/O block size. The range is 0 to 100 ms. The default is 10 ms.
length-delay value	(Optional) Amount of SNA frame data in bytes the CSNA subchannel accumulates before transmitting the accumulated channel I/O block to the attached mainframe. The range is 0 to 65535 bytes. The default is 20470 bytes.

Syntax Description

slot	Slot number.
port	Physical channel interface port number.
tg-name	(Optional) Name of the transmission group.

Syntax Description

slot	Slot number.
port	Physical channel interface port number.
path	(Optional) Logical channel path.
device	(Optional) 2-digit hexadecimal value that specifies a device address of the CPMC or CMPC+ subchannel. If specified, only status for that CMPC or CMPC+ device will be displayed. If not specified, status for all CMPC or CMPC+ devices for the specified path will be displayed.

Syntax Description

slot	Slot number.
port	Port number.
path	(Optional) A hexadecimal value in the range of 0x0000 to 0xFFFF. This specifies the data path and consists of two digits for the physical connection (either on the host or on the ESCON Director switch), one digit for the control unit address, and one digit for the channel logical address. If not specified, information is displayed for all CSNA subchannels configured on the selected interface.
device	(Optional) A hexadecimal value in the range of 0x00 to 0xFE. This is the unit address associated with the control unit number and path as specified in the host IOCP file. If not specified, information is displayed for all CSNA subchannels configured with the specified path on the selected interface.
admin	(Optional) Displays configured values for CSNA channel devices. If neither admin, oper, or stats is specified, admin is the default.
oper	(Optional) Displays operational values for CSNA channel devices.
stats	(Optional) Displays statistics for CSNA channel devices.

Syntax Description

slot	Slot number.
port	Port number.
oper	(Optional) Operational parameters for the CMPC or CMPC+ transmission group values.
stats	(Optional) Statistical values for the CMPC or CMPC+ transmission group.
detailed	(Optional) Additional information about the CMPC or CMPC+ transmission group.
tg-name	(Optional) Name of the transmission group.

Syntax Description

name	Name of the CMPC transmission group. The maximum length of the name is eight characters. This must match the name specified on the cmpc statements.
llc	Specifies that this TG is connected to the LLC stack on the CMCC adapter card.
token-adapter	Internal adapter type on the CMCC adapter card. The currently supported type is token-adapter.
adapter-number	Internal adapter number on the CMCC adapter card, which is the same value specified in the adapter internal LAN configuration command.
lsap	Local SAP number, 04 to FC, in hexadecimal. The value must be even and should normally be a multiple of four. It must be unique within the internal adapter in that no other IEEE 802.2 clients of that adapter, in the router or in a host, can use the same SAP. The default value is 04.
rmac rmac	(Optional) Remote MAC address of the form xxxx.xxxx.xxxx in hexadecimal. If not specified, a loopback link to another SAP on the same internal LAN adapter is assumed.
rsap rsap	(Optional) Remote SAP address, 04 to FC in hexadecimal. The value for the rsap argument must be even and should be a multiple of 4, but this requirement is not enforced. The default value for the rsap argument is 04.

Syntax Description

tg-name	Name of the CMPC+ transmission group. The maximum length of the name is eight characters. This name must match the name specified on the cmpc statements.
ip	Specifies that this transmission group is connected to the TCP/IP stack.
hsas-ip	Specifies that this transmission group is connected to the HSAS IP stack.
host-ip-addr	Specifies the IP address of the channel-attached host using this transmission group. A host may have more than one IP stack, therefore this is the IP address of the host IP stack as indicated by the HOME statement in the host TCP/IP profile. For HSAS, this address is the host address as indicated by the source-IP-address parameter of the oeifconfig command.
local-ip-addr	This address must match an IP address configured on the virtual interface. Specifies the IP address of the router to be used for this transmission group. This is the IP address of the router as indicated by the DEFAULTNET statement in the host TCP/IP profile. For HSAS, this address is the router IP address as indicated by the destination-IP-address parameter of the oeifconfig command.
broadcast	Enables the sending of routing updates to the host.
