Step 2: Restart a JUNOS Software Process

Action

To restart a JUNOS software process, use the following JUNOS CLI operational mode command and include the process you wish to restart. For example:

user@host> restart routing

Sample Output

user@host> restart routing
Routing protocol daemon started, pid 751

What It Means

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 18 lists and describes the options available for the restart command.

Table 18: Options to Restart a JUNOS Software 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.
