restart (Reset)



Release Information

Command introduced before Junos OS Release 9.2


Restart a Junos OS process.


Never restart a software process unless instructed to do so by a customer support engineer. A restart might cause the router to drop calls and interrupt transmission, resulting in possible loss of data.


  • application-identification—(Optional) Restart the process that identifies an application using intrusion detection and prevention (IDP) to allow or deny traffic based on applications running on standard or nonstandard ports.

  • application-security—(Optional) Restart the application security process.

  • audit-process—(Optional) Restart the RADIUS accounting process that gathers statistical data that can be used for general network monitoring, for analyzing and tracking usage patterns, and for billing a user based upon the amount of time used or the type of services accessed.

  • chassis-control—(Optional) Restart the chassis management process.

  • class-of-service—(Optional) Restart the class-of-service (CoS) process, which controls the router's or switch’s CoS configuration.

  • commitd-service—(Optional) Restart the committed services.

  • database-replication—(Optional) Restart the database replication process.

  • datapath-trace-service—(Optional) Restart the Restart the packet path tracing process.

  • ddns—(Optional) Restart the dynamic domain name system, which dynamically updates IP addresses for registered domain names.

  • dhcp—(Optional) Restart the software process for a Dynamic Host Configuration Protocol (DHCP) server. A DHCP server allocates network IP addresses and delivers configuration settings to client hosts without user intervention.

  • dhcp-service—(Optional) Restart the Dynamic Host Configuration Protocol process.

  • disk-monitoring—(Optional) Restart disk monitoring, which checks the health of the hard disk drive on the Routing Engine.

  • dynamic-flow-capture—(Optional) Restart the dynamic flow capture (DFC) process, which controls DFC configurations on PIC3 monitoring services cards.

  • ethernet-connectivity-fault-management—(Optional) Restart the process that provides IEEE 802.1ag Operation, Administration, and Maintenance (OAM) connectivity fault management (CFM) database information for CFM maintenance association end points (MEPs) in a CFM session.

  • ethernet-link-fault-management—(Optional) Restart the process that provides the OAM link fault management (LFM) information for Ethernet interfaces.

  • event-processing—(Optional) Restart the event process (eventd).

  • extensible-subscriber-services—(Optional) Restart the extensible subscriber services process.

  • fipsd—(Optional) Restart the fipsd services.

  • firewall—(Optional) Restart the firewall management process, which manages the firewall configuration and accepts or rejects packets that are transiting an interface on a router or switch.

  • firewall-authentication-service—(Optional) Restart the firewall authentication service process.

  • general-authentication-service—(Optional) Restart the general authentication process.

  • gprs-process—(Optional) Restart the General Packet Radio Service (GPRS) process.

  • gracefully—(Optional) Restart the software process.

  • idp-policy—(Optional) Restart the intrusion detection and prevention (IDP) protocol process.

  • immediately—(Optional) Immediately restart the software process.

  • interface-control—(Optional) Restart the interface process, which controls the router's or switch’s physical interface devices and logical interfaces.

  • ipmi—(Optional) Restart the intelligent platform management interface process.

  • ipsec-key-management—(Optional) Restart the IPsec key management process.

  • jflow-service—(Optional) Restart jflow service process.

  • jnu-management—(Optional) Restart jnu management process.

  • jnx-wmicd-service—(Optional) Restart jnx wmicd service process.

  • jsrp-service—(Optional) Restart the Juniper Services Redundancy Protocol (jsrdp) process, which controls chassis clustering.

  • kernel-replication—(Optional) Restart the kernel replication process, which replicates the state of the backup Routing Engine when graceful Routing Engine switchover (GRES) is configured.

  • lacp—(Optional) Restart the Link Aggregation Control Protocol (LACP) process. LACP provides a standardized means for exchanging information between partner systems on a link. The LACP process allows link aggregation control instances to reach agreement on the identity of the LAG to which a link belongs, moves the link to that LAG, and enables the transmission and reception processes for the link to function in an orderly manner.

  • l2cpd-service—(SRX5400, SRX5600, and SRX5800 devices only) (Optional) Restart the Layer 2 Control Protocol (L2CP) process, which enables features such as L2 protocol tunneling and nonstop bridging.

  • l2-learning—(Optional) Restart the Layer 2 (L2) address flooding and learning process.

  • license-service—(Optional) Restart the feature license management process.

  • logical-system-service—(Optional) Restart the logical system service process.

  • mib-process—(Optional) Restart the MIB version II process, which provides the router's MIB II agent.

  • mountd-service—(Optional) Restart the service for Network File System (NFS) mount requests.

  • named-service—(Optional) Restart the DNS Server process, which is used by a router or a switch to resolve hostnames into addresses.

  • network-security—(Optional) Restart the network security process.

  • network-security-trace—(Optional) Restart the network security trace process.

  • nfsd-service—(Optional) Restart the remote NFS server process, which provides remote file access for applications that need NFS-based transport.

  • ntpd-service—(Optional) Restart the Network Time Protocol (NTP) process.

  • pgm—(Optional) Restart the process that implements the Pragmatic General Multicast (PGM) protocol for assisting in the reliable delivery of multicast packets.

  • pic-services-logging—(Optional) Restart the logging process for some PICs. With this process, also known as fsad (the file system access daemon), PICs send special logging information to the Routing Engine for archiving on the hard disk.

  • pki-service—(Optional) Restart the public key infrastructure (PKI) service process.

  • profilerd—(Optional) Restart the profiler process.

  • remote-operations—(Optional) Restart the remote operations process, which provides the ping and traceroute MIBs.

  • rest-api—(Optional) Restart the rest api process.

  • routing—(Optional) Restart the routing protocol process (rpd).

  • sampling—(Optional) Restart the sampling process, which performs packet sampling based on particular input interfaces and various fields in the packet header.

  • sampling-route-record—(Optional) Restart the sampling route record process.

  • scc-chassisd—(Optional) Restart the scc chassisd process.

  • secure-neighbor-discovery—(Optional) Restart the secure Neighbor Discovery Protocol (NDP) process, which provides support for protecting NDP messages.

  • security-intelligence—(Optional) Restart security intelligence process.

  • security-log—(Optional) Restart the security log process.

  • service-deployment—(Optional) Restart the service deployment process, which enables Junos OS to work with the Session and Resource Control (SRC) software.

  • services—(Optional) Restart a service.

  • simple-mail-client-service—(Optional) Restart the simple mail client service process.

  • snmp—(Optional) Restart the SNMP process, which enables the monitoring of network devices from a central location and provides the router's or switch’s SNMP master agent.

  • static-routed—(Optional) Restart the static routed process.

  • soft—(Optional) Reread and reactivate the configuration without completely restarting the software processes. For example, BGP peers stay up and the routing table stays constant. Omitting this option results in a graceful restart of the software process.

  • statistics-service—(Optional) Restart the process that manages the Packet Forwarding Engine statistics.

  • subscriber-management—(Optional) Restart the subscriber management process.

  • subscriber-management-helper—(Optional) Restart the subscriber management helper process.

  • system-log-vital—(Optional) Restart system log vital process.

  • tunnel-oamd—(Optional) Restart the tunnel OAM process for L2 tunneled networks.

  • uac-service—(Optional) Restart the Unified Access Control (UAC) process.

  • user-ad-authentication—(Optional) Restart User ad Authentication process

  • vrrp—(Optional) Restart the Virtual Router Redundancy Protocol (VRRP) process, which enables hosts on a LAN to make use of redundant routing platforms on that LAN without requiring more than the static configuration of a single default route on the hosts.

  • web-management—(Optional) Restart the Web management process.
