How to limit download and upload speeds on Juniper SRX100

‎12-31-2017 07:21 AM

Hello everyone,

 

How can I limit download and upload speed on Juniper SRX100? I am trying to limit the download speed for all connected devices to about 20-25 Mbps and limit the upload speed to about 3-4 Mbps. I read that some people do it with firewall and whatnot but I am not sure how I can do it myself. Please help thank you!

Basic limits by interface are done using policers.

Hello,

In addition to what has been said - You could use SRX' "firewall filters" (not to be confused with stateful filtering policies) with policers :

1/ by manually configuring a separate filter term for each individual IP - if the number of "connected devices" is low (dozen or so)

2/ by using "then prefix-action" feature - it autocreates policers and counters given the connected subnet and granularity

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/policer-prefix-specific-policing-...

I see "then prefix-action" knob is hidden in 12.1X46, so please check the version You are running

3/ by using JUNOS Automation (SLAX or Python script) that would auto-configure filter terms + policers for You once You add a connected subnet.

Essentially, #3 is the same as #2 but done using on-box script.

HTH

Thx
Alex

You can get high tech and granular if you want to go for the rete  limiters in AppQoS.
