Investigate tasks that, for no apparent reason, show CPU utilization consistently above 25% (except for
the BGTask). Configure the appropriate debug-trace command and look for messages indicating a
problem. Common problems are source or destination addresses.
tPimTask
The protocol independent multicast task (tPimTask) implements and processes PIM on the
switch.
NOTE: This option is available only on the “
i
” series switches.
tPingServer
The server load balancing (SLB) Layer 3 ping health check sub-task.
NOTE: This option is available only on the “
i
” series switches.
tPortProbe
A server load balancing (SLB) Layer 4/Layer 7 health check sub-task.
NOTE: This option is available only on the “
i
” series switches.
tPortUtilization
The port utilization data collection task (tPortUtilization) is a 30 second task that pulls physical
port data statistics from the hardware and updates the software database tables.
tRip
The Routing Information Protocol task (tRip) implements and processes RIP on the switch.
tRipTimer
The RIP timer task (tRipTimer) manages the internal timer trigger functions and delays for RIP.
TRmonTask
The remote monitoring task
tRRPoll
The Road Runner poll task (tRRPoll) pulls the MAC and PHY layer statistics from the store in
the software based tables.
tRxMsgTask
The receive message task (tRxMsgTask) is located on the secondary system. ExtremeWare 6.2
commences use of the secondary CPU in BlackDiamond switches. This is the secondary slave
CPU inter-CPU receive task.
tServAlive
The server load balancing (SLB) health check server task.
NOTE: This option is available only on the “
i
” series switches.
tShell
The core operating system internal shell process (tShell) is spawned whenever the internal
shell is accessed.
tSlbFailover
The server load balancing failover task.
tSlowTimer
The slow timer task (tSlowTimer) maintains a queue of timer events triggering periodic or single
event functions. Typically these events have a large period gap in terms of time between
recurrences.
tsmartTrap
Extreme smart trap task.
tSnmpd
The SNMP daemon task manages all SNMP processing on the system.
tSntpc
The simple network time protocol client task (tSntpc) implements the SNTP client function and
processing.
tsshshell
The secure shell (SSH) task.
tStatsPoll
The port interface statistics poll task (tStatsPoll) polls the port interfaces for statistic counters.
tstpTask
The Spanning Tree protocol task (tstpTask) implements the STP algorithm and processing.
tSwFault
The software fault handler task (tSwFault) will perform a stack dump for any task that has
crashed.
tsyslogTask
The system log task (tsyslogTask) receives messages/text from other tasks and asynchronously
logs these to the switch NVRAM log area.
tTimeout
The Timeout task (tTimeout) is used to manage and execute various functions on timeouts.
tTRRecv
The trace route receiver task (tTrRecv) is spawned dynamically when the trace route utility is
used.
tvrrpTask
The virtual router redundancy protocol task (tvrrpTask) implements and processes VRRP on the
switch.
