Event Log Commands
Using the •Create Link File Directories" (CD) command, a Link File directory can be created for each LANIC card installed. Once created, a card's Link File directory contains a MCAST.TXT file and an EL.TXT file. The Link File directory, MCAST.TXT file, and EL.TXT file are contained in a root directory, FILES802, of a disk"based File Server Node (see Chapter 4).
The MCAST.TXT file is used for storing Multicast Addresses to be configured on the applicable card (see Chapter 4).
The EL.TXT (or event log) file is used for logging of certain events. When a card is properly configured, its EL.TXT file is accessed by Node Manager software to record occurrences of •bad", •orphan", or •trace" packets received, that is,
Dpackets with a Cyclic Redundancy Check or Length errors (bad);
Dpackets that cannot be routed to an intended program or process due to an invalid or nonexistent class number posted to the packet's DSAP (orphan);
Dpackets resulting from self"addressed TEST and XID commands that specify a DSAP of •00" (treated as orphans); and
Dpackets unsuccessfully transmitted and returned to the driver (trace).
The complete path to the EL.TXT file is as follows:
/FILES802/ADDRxxxxxxxxxxxx/EL.TXT
where xxxxxxxxxxxx are hexadecimal digits of the associated card's Station Address.
There is only one Event Log command. The Read Event Log File (RE) command is used for reading the EL.TXT file.
