System module descriptions

RCS 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.
RKD These messages are either error or informational messages pertaining to the Rekey daemon of the
Fabric OS.
RMOND RMOND messages are error or informational messages pertaining to the RMOND daemon.
RPCD The remote procedure call daemon (RPCD) is used by Fabric Access for API-related tasks.
RTE 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.
RTWR 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.
SAS Storage application services supporting director-class storage virtualization platforms.
SCN The internal state change notification daemon is used for state change notifications from the kernel
to the daemons within Fabric OS.
SEC 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 attack.
SFLOW sFlow is a standard-based sampling technology embedded within switches and routers which is used
to monitor high speed network traffic.
sFlow uses two types of sampling:
• Statistical packet-based sampling of switched or routed packet flows.
• Time-based sampling of interface counters.
SNMP 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 SPC messages indicate problems and informational updates associated with the security processor.
These messages could be tiggered by the following three modules: Security processor controller, SP
system controller, and SP Keyapp.
SPM Error messages indicating problems either with key or SP management.
SS The supportSave command generates these error messages if problems are encountered.
SSM SSM error messages indicate problems with the System Services Module of the Fabric OS.
SULB 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.
SWCH These messages are generated by the switch driver module that manages a Fibre Channel switch
instance.
