Restart a Junos OS Process
Action
To restart a Junos OS process, use the following Junos OS CLI operational mode command and include the process you wish to restart. For example:
Sample Output
user@host> restart routing
Routing protocol daemon started, pid 751
Meaning
The sample output shows that the routing protocol daemon was restarted and the process identification (PID) was changed from 685 in the previous sample output to 751.
Table 1 lists and describes the options available for the restart command.
Table 1: Options to Restart a Junos OS Process
Option | Description |
|---|---|
class-of-service | Restart the class-of-service process, which controls the router’s class-of-service configuration. |
gracefully | Restart the software process by sending the equivalent of a UNIX SIGTERM signal. |
immediately | Immediately restart the process by sending the equivalent of a UNIX SIGKILL signal. |
interface-control | Restart the interface process, which controls the router’s physical interface devices and logical interfaces. |
mib-process | Restart the Management Information Base (MIB) II process, which provides the router’s MIB II agent. |
network-access-service | Restart the network access process, which provides the router’s Challenge Handshake Authentication Process (CHAP) authentication service. |
remote-operations | Restart the remote operations process, which provides the ping and traceroute MIBs. |
routing | Restart the routing protocol process, which controls the routing protocols that run on the router and maintains the routing tables. |
sampling | Restart the sampling process, which performs packet sampling and cflowd export. |
snmp | Restart the Simple Network Management Process (SNMP) process, which provides the router’s SNMP master agent. |
soft | Reread and reactivate the configuration without completely restarting the software processes. For example, Border Gateway Protocol (BGP) peers stay up and the routing table stays constant. This option is the equivalent of a UNIX SIGHUP signal; omitting this option is the equivalent of a UNIX SIGTERM (kill) operation. |
