tIpxTx The IPX transmit task (tIpxTx) handles the IPX transmission of control packets such
as RIP and SAP.
tIquery The iQuery support task for 3DNS (tIquery) processes iQuery requests.
TIRDP The ICMP router discovery protocol task (tIRDP) implements and processes IRDP on
the switch.
tISRtask The interrupt service routine task (tISRtask) manages the interrupt driven port link
state changes.
tLinkEvent The link event task (tLinkEvent) is the interrupt driven link event processing task. It
handles hardware interrupts for link events.
tMACPoll The media access controller poll task (tMACPoll) polls the various MAC PHY chips
on the switch to pull up MAC Layer control messages for the CPU to process.
tmt32LinkPoll F32F module link poll task.
tmuTelnetd The telnet daemon task.
tNetTask The network stack task (tNetTask) handles all the software-based processing of
packets including:
• Packets that cannot be handled by the switch's ASIC because the forwarding
tables do not have entries built in.
• Packets destined to the CPU for one of the router interfaces.
• Packets that must be examined or snooped by the CPUPackets detected for
copying to the CPU.
tNMCEvent The network management controller event task (tNMCEvent) manages event
signaling hardware and state machine on a BlackDiamond switch’s redundant MSM
CPU modules.
tOpenPort A server load balancing (SLB) Layer 4/Layer 7 health check sub-task.
tospfMsgTask The OSPF message processing task (tospfMsgTask) implements and manages the
processing of OSPF messages.
tospfSpfTask The OSPF shortest path forward task (tospfSpfTask) executes the SPF algorithm run
processing for OSPF.
tospfTimer The OSPF timer task (tospfTimer) manages the internal timer trigger functions and
delays for OSPF.
tPCSPoll The tPCSPoll task services the Gigabit Ethernet PCS poll messages.
tPhyPoll The PHY layer poll task (tPhyPoll) polls the Road Runner PHY layer every 2
seconds to verify the proper operation.
tPimTask The protocol independent multicast task (tPimTask) implements and processes PIM
on the switch.
tPingServer The server load balancing (SLB) Layer 3 ping health check sub-task.
tPortProbe A server load balancing (SLB) Layer 4/Layer 7 health check sub-task.
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.
