  • 1.  Juniper Srx 345 - Have i hit hardware limits?

    Posted 07-05-2022 12:03

    Hello

    Could use some help deciding if i hit hardware limit or i have bad config.

    Device: Juniper srx345-dual-ac, fw 21.2R1.10

    When reading datasheet it states the following:

    Routing with packet mode (IMIX packet size) 2,300 Mbps
    Stateful firewall (IMIX packet size) 1700 Mbps
    IPsec VPN (IMIX packet size) 300 Mbps

    In short i have one uplink to internet and one trunk port with 9 vlans. There is about 350/350 traffic on trunk port between vlans. And 30/15 on ipsec tunnel over internet. Currently i have security policies that allow all traffic between vlans. Not global but seperate one for each vlan.

    Security loging mode is set to event, changing to streaming didnt change much.

    With this simple setup the load is following:

    Probably making myself look stupid but I don't see it or don't understand. Sorry, why do you think you have a problem?

    Hello

    Problem comes from fact that 350/350mb traffic between different zones makes router use 85-99% of the cpu and traffic starts lagging. Datasheet suggests that so litle traffic should be easyle handled.

    Use case: zone 1 has about 100 cameras, zone 2 has recording servers that record zone 1 cameras, zone 3 has client pc-s that stream from recording servers. and so fort. There is one trunk port in router that carries all the different vlans (in different zones). Currently very basic firewall setup and no other advanced features running. Its enought to get router to 99% utilisation.

    During one of the periods of high cpu run these commands to see which process is responsible for the high cpu.  Once the process is identified it will be easier to see the cause.

    show chassis routing-engine

    show system processes extensive | except 0.0

    show system queues
