Syntax
ipv4-flow-table-size units;
Hierarchy Level
[edit chassis fpc slot-number inline-services flow-table-size]
Description
Configure the size of the IPv4 flow table in units of 256K entries.
Prior to Junos OS Release 16.1R1 and 15.1F2, any changes in the configured size of the flow table initiates an automatic reboot of the FPC, and we recommend that you run this command in a maintenance window.
Starting with Junos OS Release 16.1R1 and 15.1F2, by default, the software allocates
1K entries for IPv4 flow tables. To allocate fifteen 256K IPv4 flow tables, the
former default, you can enter this configuration from the [edit]
hierarchy level:
[edit] user@router# set chassis fpc slot-number inline-services flow-table-size ipv4-flow-table-size 15
Starting with Junos OS Release 17.3R1, the maximum supported flow table size varies by line card type:
