- LLC2 Station, SAP, and Connection Statistics
llc2_stats ppa [-r] [-s sap] [-c connection]
The llc2_stats command is used to retrieve statistical information from the Host-based Logical Link Control Class 2 component of the LLC2 Driver. Statistics are kept for the station, SAP (Service Access Point), and connection components.
The following options are supported:
Specifies the connection of interest. Its value is entered in hexadecimal notation with no leading 0x.
Resets the specified counters to zero after reading them. This option is only valid if the root user is executing the command.
Specifies the SAP for this request. It is a single-byte value, expressed in hexadecimal notation with no leading 0x. For example, the NetBIOS sap, 240 (0xf0) would be entered as: -s f0.
The following operand is supported:
The logical number used to address the adapter. The PPA (Physical Point of Attachment) must be the first argument.
Example 1 Station Statistics
The following command will display the station statistics for PPA 4. After the example, a brief description of each field is presented.
example% /usr/lib/llc2/llc2_stats 4 Station values received: ppa = 0x00000004 clearFlag = 0x00 # of saps (hex) = 0x0002 saps (hex) = 02 aa state = 0x01 nullSapXidCmdRcvd = 0x00000000 nullSapXidRspSent = 0x00000000 nullSapTestCmdRcvd = 0x00000000 nullSapTestRspSent = 0x00000000 outOfState = 0x00000000 allocFail = 0x00000000 protocolError = 0x00000000
