Output Fields

Table 1 lists the output fields for the show chassis routing-engine command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis routing-engine Output Fields

Field Name

Field Description

Temperature

Routing Engine temperature. (Not available for vSRX Virtual Firewall deployments.)

CPU temperature

CPU temperature. (Not available for vSRX Virtual Firewall deployments.)

Total memory

Total memory available on the system.

Note:

Starting with Junos OS Release 15.1x49-D70 and Junos OS Release 17.3R1, there is a change in the method for calculating the memory utilization by a Routing Engine. The inactive memory is now subtracted from the total available memory. There is thus, a decrease in the reported value for used memory; as the inactive memory is now considered as free.

Control plane memory

Memory available for the control plane.

Data plane memory

Memory reserved for data plane processing.

CPU utilization

Current CPU utilization statistics on the control plane core.

User

Current CPU utilization in user mode on the control plane core.

Background

Current CPU utilization in nice mode on the control plane core.

Kernel

Current CPU utilization in kernel mode on the control plane core.

Interrupt

Current CPU utilization in interrupt mode on the control plane core.

Idle

Current CPU utilization in idle mode on the control plane core.

Model

Routing Engine model.

Start time

Routing Engine start time.

Uptime

Length of time the Routing Engine has been up (running) since the last start.

Last reboot reason

Reason for the last reboot of the Routing Engine.

Load averages

The average number of threads waiting in the run queue or currently executing over 1-, 5-, and 15-minute periods.

The Total memory 64 GB is distributed between the routing engine in the form of virtual machine for the TVP platforms (SRX1500, SRX4100, SRX4200) and the rest for the packet forwarding engine (PFE). TVP has a different architecture differentiating PFE from Junos and additional API compatibility. The above mentioned devices are the only ones with this TVP architecture in SRX. The show chassis routing-engine command displays only the Routing Engine memory.
