SFLO 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.
SFLO messages indicate error or information related to sflowd daemon.
SNMP Simple Network Management Protocol (SNMP) is an 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.
SS The copy support command generates these error messages if problems are encountered.
SSMD SSMD error 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. These messages may display if
there are any problems during the firmware download procedure. Most messages are informational
only and are generated even during successful firmware download.
TOAM TRILL OAM (TOAM) module messages indicate problems with the l2traceroute family of commands
that help in VCS cluster data path troubleshooting.
TRCE The TRCE module messages describe events and problems associated with the tracedump facility.
TS Time Service provides switch time-synchronization by synchronizing all clocks in the network.
VC VC module messages indicates any important information related to the vCenter CLI and its plugins.
VCS VCS messages indicate major events related to VCS cluster formation and node operations.
ZONE The zone module messages indicate any problems associated with the zoning features, including
commands associated with aliases, zones, and configurations.
