Article ID: KB28521 KB Last Updated: 05 Mar 2017Version: 2.0

This article explains how many session wings are supported on NPC.


How many session wings are supported on NPC?



SRX5k standard IOC: 1.5M sessions / 3M wings*

SRX5k FlexIOC: 3M sessions / 6M wings*

SRX1k/3k NPC: 3M sessions / 6M wings*

Note: A wing is half a session – a session is bidirectional (outbound and return traffic) and a wing is unidirectional (outbound OR return traffic).

*In Junos OS 11.4, we got a 50% increase in NPU session counts for all NPUs. If you are running pre-11.4 code, then decrement your capacity accordingly.
