Description Function
Daughter Card Manager Responsible for managing IPSec Security Associations for
AH- and ESP-based sessions.
[ASR 5x00 only]
Interfaces with the on-board hardware accelerated
cryptographic chip which executes cryptographic algorithms
associated with the given IPSec Security Associations.
Distributed Host Started automatically on each CPU by SITPARENT.
Manager
Coordinates establishment of locally terminated TCP, SCTP,
and UDP connections on behalf of multi-instanced tasks such
as Diameter endpoints among sessmgr tasks.
Driver Controller Centralizes access to many of the system device drivers. It
also performs temperature and voltage monitoring.
Hard Drive Controller Controls and manages the drive array spanning the
management cards.
Hardware Controller The hwctrl task has several timers that manage polling loops
for hardware sensor readings, sensor threshold monitoring,
and fan tray monitoring.
Hardware Manager The hwmgr task runs on all cards in the chassis to read local
accessible hardware sensors and report them back to the
hwctrl.
InterNET Service The subsystem responsible for starting most of the network
Daemon services.
Listens for requests from connecting clients, such as FTP,
SFTP, and telnet. When a TCP packet or UDP packet arrives
with a particular destination port number, inetd launches the
appropriate server program to handle the connection.
IPSec Controller Started by SIT on system startup regardless of configuration.
Starts ipsecmgr tasks based on configuration and maintains
its list for task recovery.
Receives and maintains user configuration for IPSec.
Manages the configured IPSec crypto maps and its assignment
to ipsecmgrs.
Interfaces with the vpnmgr task for required IPSec
configuration parameters such as IP Access Lists, IP pools,
interface addresses, and interface state notifications.
IPSec Manager Created by the Session Controller, establishes and manages
secure IKEv1, IKEv2 and IPSec data tunnels.
