PORT

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.

PS

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.

PSWP

The portswap feature and associated commands generate these error messages.

RAS

Informational messages when first failure data capture (FFDC) events are logged to the FFDC log
and size or roll-over warning.

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 re-key daemon of the
Fabric OS.

RMON

RMON 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.

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 attacks.

SFLO

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.

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 triggered 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.
