RAS RAS messages notify when first failure data capture (FFDC) events are logged to the FFDC log, and
size or roll-over warnings.
RCS The reliable commit service (RCS) daemon generates log entries when it receives a request from
the zoning or security server for passing data messages to switches. 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 or Security modules.
RTM Route Manager (RTM) messages indicate status or errors while updating or maintaining the route
and next-hop database.
RTWR The reliable transport write (RTWR) and read daemon helps deliver data messages either to
specific switches in the fabric or to all 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 Network OS.
SEC SEC messages indicate security errors, warnings, or information during security-related data
management or fabric merge operations. Administrators must watch for these messages to
distinguish between internal switch and fabric operation errors and external attack.
SFLO sFlow is a standards-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.
SFLO messages indicate errors or information related to the sflow daemon.
SLCD SLCD messages provide wear level statistics of the western digital (WD) SiliconDrive 2 compact
flash.
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 four management entities that can be configured to receive these traps or
informs.
SNMP messages indicate problems in the SNMP operations.
SRM System Resource Monitor daemon monitors memory and CPU usage of all processes. The SRM
message is generated when the available Low memory is below 100 MB.
SS SS messages indicate problems during the execution of the copy support command.
SSMD SSMD messages indicate problems with the System Services Module (SSM) of the Network OS.
SULB The software upgrade library provides the firmware download command capability, which enables
firmware upgrades as well as nondisruptive code load to the switches. SULB messages may
display if there are any problems during the firmware download procedure.
SWCH SWCH messages are generated by the switch driver module that manages a Fibre Channel switch
instance.
TNLD TNLD messages indicate status or problems with the Data Center Ethernet (DCE) tunnel manager
of the Network OS.
TOAM TRILL OAM (TOAM) messages indicate problems with the l2traceroute family of commands that
help in VCS cluster data path troubleshooting.
