System module descriptions 1 TABLE 6 System module PORT PS PSWP RAS RCS RKD RMON RPCD RTE RTWR SCN SEC SFLO SNMP SPC SPM SS System module descriptions (Continued) Description PORT error messages refer to the front-end user ports on the switch. Front-end user ports are directly accessible by users to connect end devices or connect to other switches. The performance server daemon measures the amount of traffic between endpoints or traffic with particular frame formats, such as SCSI frames, IP frames, and customer-defined frames. The portswap feature and associated commands generate these error messages. Informational messages when first failure data capture (FFDC) events are logged to the FFDC log and size or roll-over warning. The reliable commit service daemon generates log entries when it receives a request from the zoning, security, or management server for passing data messages to switches in the fabric. RCS then requests reliable transport write and read (RTWR) to deliver the message. RCS also acts as a gatekeeper, limiting the number of outstanding requests for the Zoning, Security, or Management Server modules. These messages are either error or informational messages pertaining to the re-key daemon of the Fabric OS. RMON messages are error or informational messages pertaining to the RMOND daemon. The remote procedure call daemon (RPCD) is used by Fabric Access for API-related tasks. 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. 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. Fabric OS Message Reference 33 53-1002749-01
