Environment

Juniper equipment

Problem

If you've configured Juniper by our guidelines( https://www.netvizura.com/blog/flow-export-configuration-on-juniper-network-devices ) and you still see lower throughput than it should be.

Cause

Juniper setting newer JunOS releases ipv4-flow-table to 4

Solution

  1. Consult: https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/ipv4-flow-table-size.htmlC

      2. In most cases setting  edit chassis fpc slot-number inline-services flow-table-size to 15 should do the trick. Be careful that if you do this on older JunOS releases you could initiate restart.
