System module descriptions 1 TABLE 6 System module SNMP SPC SPM SS SSM SULB SWCH SYSC SYSM TAPE TRCE TRCK TS UCST UPTH VS WEBD System module descriptions (Continued) Description Simple Network Management Protocol (SNMP) is a universally supported low-level protocol that allows simple get, get next, and set requests to go to the switch (acting as an SNMP agent). It also allows the switch to send traps to the defined and configured management station. Brocade switches support six management entities that can be configured to receive these traps. SPC messages indicate problems and informational updates associated with the security processor. These messages could be triggered by the following three modules: Security processor controller, SP system controller, and SP Keyapp. Error messages indicating problems either with key or SP management. The supportSave command generates these error messages if problems are encountered. SSM error messages indicate problems with the System Services Module of the Fabric OS. The software upgrade library provides the firmwareDownload command capability, which enables firmware upgrades to both CP blades with a single command, as well as nondisruptive code load to all Fabric OS 4.x switches. These messages might display if there are any problems during the firmwareDownload procedure. Most messages are informational only and are generated even during successful firmware download. For additional information, refer to the Fabric OS Administrator's Guide. These messages are generated by the switch driver module that manages a Fibre Channel switch instance. System controller is a daemon that starts up and shuts down all Fabric OS modules in the proper sequence. General system messages. A kernel-space driver that handles all I/O operations aimed at Tape containers. RAS TRACE error messages. The track change feature tracks the following events: • Turning on or off the track change feature • CONFIG_CHANGE • LOGIN • LOGOUT • FAILED_LOGIN If any of these events occur, a message is sent to the system message log. Additionally, if the SNMP trap option is enabled, an SNMP trap is also sent. For information on configuring the track change feature, refer to the Fabric OS Command Reference or the Fabric OS Administrator's Guide. Time Service provides fabric time-synchronization by synchronizing all clocks in the fabric to the clock time on the principal switch. UCST is a part of the fabric shortest path first (FSPF) protocol that manages the Unicast routing table. UPATH is a part of the FSPF protocol that uses the SPF algorithm to dynamically compute a Unicast tree. The VS module messages indicate any problems or information associated with the Dynamic Fabric Provisioning feature, including commands associated with the fapwwn command and configurations. Indicates problems with the Web Tools module. Fabric OS Message Reference 29 53-1002448-01
