Usefull Juniper SRX commands

This post contains several useful Junos SRX commands for the CLI. Mainly for myself, because I don't use those command regularly....

This post will be updated over time... Here it goes:

View session information:

root@srx100> show security flow session summary

Clear sessions through the firewall:

root@srx100> clear security flow session all

Switch to other node in a cluster via CLI (over the HA-link):

root@srx100> request routing-engine login node 1

Enable Juniper SRX Firewall Logging

Juniper started to migrate their firewalls from Netscreen to the Junos environment 'a couple of' months back. The advantage is that there's a universal OS for routers, switches and firewalls. Just like Cisco IOS. The disadvantage is that the Junos OS is being adapted for the firewalls. So the foundations are there, but there are still lots of features missing and bugs are also still abundant.

The bugs are thankfully mostly related to the WebGUI. On the commandlinethe bugs are in the same league as the Cisco, Checkpoint and every other vendor bugs. No piece of software is perfect.
