Additional Features
We have extended support for the following features to these platforms.
Support for preventing event, op, SNMP, or JET script execution based on current system memory usage (SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, and SRX5800)
Supported transceivers, optical interfaces, and DAC cables Select your product in the Hardware Compatibility Tool (https://apps.juniper.net/hct/product/) to view supported transceivers, optical interfaces, and direct attach copper (DAC) cables for your platform or interface module. We update the HCT and provide the first supported release information when the optic becomes available.
On-box monitoring support on the control plane (SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, and SRX5800).You can configure the memory monitoring system to monitor the system memory and raise a major or minor alarm using the
set system monitor memory system alarm
command statement on a device. The system raises an alarm when the device runs low on memory.[See Memory (System).]
Reduce operational time by using the JET Interfaces Service API to perform port bounces (SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, and SRX5800)
