Default SNMP Permission Level

C

The default SNMP permission level on Junos devices is "read-only".

SNMP (Simple Network Management Protocol) is a standard protocol used to manage and monitor network devices. It allows network administrators to remotely monitor and configure network devices such as routers, switches, and servers.

SNMP uses a set of permissions to control access to the information and configuration settings on network devices. These permissions include read-only, read-write, and write.

The "read-only" permission level allows SNMP managers to retrieve information from the device, but they cannot make any changes or modify the device's configuration. This is the default permission level on Junos devices, and it is sufficient for most network monitoring tasks.

The "read-write" permission level allows SNMP managers to retrieve information from the device and also modify its configuration settings. This level of access is typically reserved for network administrators who need to make changes to the device's configuration.

The "write" permission level allows SNMP managers to modify the device's configuration settings without being able to retrieve any information from the device. This level of access is not commonly used, as it can be risky to allow changes to be made to a device without being able to verify its current state.

In summary, the default SNMP permission level on Junos devices is "read-only", which allows SNMP managers to retrieve information from the device but not make any changes to its configuration settings.
