Description
The HTTP daemon task manages the HTTP web management interface on the system.
In an active dual CPU system, the master CPU will initiate the log polling task (Logpoll) to
periodically poll the secondary or slave CPU(s). This process clears the individual syslogs and
consolidates them onto the master CPU switch log.
The management port task.
The port interface state task (pifstate) processes port link state changes. It is watchdog timer
poll driven as opposed to interrupt driven by hardware events.
This task is used for Agent-X implementation on the switch.
This task is used to process Agent-X related traps.
The tAsyncSave tasks the NVRAM asynchronous save/write processing task. This process
manages the save or writes to the NVRAM.
The tAXDn task is used to download the configuration to the sub agent.
This task is used to register the Agent-X subagent (local subagent residing on the switch) with
the Agent-X master.
The tAXTimerTask task is used to process Agent-X related timers.
The border gateway protocol task (tbgpTask) implements and processes BGP on the switch.
NOTE: This option is available only on the "i" series switches.
The BGP internal process timer task (tbgpTimerTask) manages the internal BGP timer delays
for checking BGP networks and next hops.
NOTE: This option is available only on the "i" series switches.
The background Quality of Service monitor task (tBgQosMon) is a background version of the
QoS monitoring task that monitors transmit count and kill count of ports and cycles as long as
the monitor is enabled.
The background task (tBGTask) is the core task switching process. It receives packets from the
hardware ASICs and switches them to the appropriate functional task to process that packet
type or group. The tBGTask typically runs with a high CPU utilization (90% or greater). It is
constantly checking for packets to be sent up by the hardware ASICs. It only releases control of
the CPU if packets are sent to the switch or if timer functions signal another task to become
active.
The I/O card event task (tCardTask) manages the event signaling hardware and state machine
for the I/O modules in a chassis-based system.
This cable diagnostic module takes care of cable diagnostic routines.
The checksum polling task (tChecksumPoll) periodically polls the boards for fabric checksum
errors.
The console task.
The diagnostic task (tdiagTask) executes the diagnostic routines for the particular hardware
platform.
The distance vector multicast routing protocol task (tDvmrpTask) implements and processes
DVMRP on the switch.
NOTE: This option is available only on the "i" series switches.
The Ethernet automatic protection switching task implements and processes EAPS on the
switch.
The Extreme Discovery Protocol task (tEdpTask) implements and processes the EDP neighbor
discovery process.
The Extreme Standby Router Protocol (tEsrpTask) implements and processes ESRP on the
switch.
