Session ager is a mechanism on SRX devices that takes care of continuous session age-out and cleanup process. This is done by running a timer on each SPU that uses ticks as a unit of time (provided by hardware). The goal of this article is to describe a way to check if the session ager tick counter is increasing on each SPU. In certain troubleshooting scenarios, where you … [Read more...]
Clock is not synchronized between RE and data-plane modules (SPC, SPU, CPP)
This article explains why the clock may be unsynchronized between the Routing Engine (RE) and the data-plane modules (SPC, SPU, CPP) on the High-End SRX device, when no external NTP servers are used. It also provides a workaround that helps to keep all the modules synchronized. When an external NTP server is not configured on the High-End SRX device, the clock on the … [Read more...]
