System module descriptions 1 TABLE 6 System module RTE RTWR SCN SEC SFLO SNMP SPM SS SSLP SSMD SULB SWCH SYSC SYSM TRCE System module descriptions (Continued) Description RTE is responsible for determining the correct paths for each ingress frame and populating the routing tables in the ASICs with this information. The ASIC then uses the information available in the routing tables to determine the path a particular ingress frame needs to take before it exits the switch. The reliable transport write and read daemon helps deliver data messages either to specific switches in the fabric or to all of the switches in the fabric. For example, if some of the switches are not reachable or are offline, RTWR returns an "unreachable" message to the caller, allowing the caller to take the appropriate action. If a switch is not responding, RTWR retries 100 times. The internal state change notification daemon is used for state change notifications from the kernel to the daemons within Fabric OS. The security daemon generates security errors, warnings, or information during security-related data management or fabric merge operations. Administrators should watch for these messages to distinguish between internal switch and fabric operation errors and external attacks. sFlow is a standard-based sampling technology embedded within switches and routers, which is used to monitor high-speed network traffic for Data Center Ethernet (DCE) and Converged Enhanced Ethernet (CEE) platforms. sFlow uses two types of sampling: • Statistical packet-based sampling of switched or routed packet flows. • Time-based sampling of interface counters. SFLO messages indicate errors or information related to the sflowd daemon. 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. Error messages indicating problems either with key or SP management. The supportSave command generates these error messages if problems are encountered. The SLP module messages indicate any problems associated with the launch of open SLP process in the switch. SSMD 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 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. RAS TRACE error messages.
