R80.20 - new interesting commands

I've been testing R80.20 very intensively in the lab over the last few days. Here I have discovered some interesting new commands on CLI. What did you discover that didn't exist before?

# cphaprob stat     > with more clusterxl informations

# fwaccel ranges   > show's anti spoofing ranges

# fw ctl multik utilize   > shows the CoreXL queue utilization for each CoreXL FW instance

# fw ctl multik print_heavy_conn   > shows the table with heavy connections

Hello Heiko,

I use R80.20 and can not found this command:

# iotop -b -n 1

Hi Marco,

It is only available on gateway with R80.20 3.10 kernel.

got a little bit confusing about the answer as "only with 3.10 kernel". Is the release R80.20 with the fixed kernel rollout or the kernel could be changed from Administrator or could be different by different R80.20-Rollout Variation?

iotop is Linux command, BTW. It is available for newer Linux distributions than 2.6 kernel based

At R80.20 there's a new hack to turn the CoreXL instances on the fly on and off. Here is an example with 3 FW wokers!

Now start the command:

# fw ctl multik stop     -> stop CoreXL instance 1

# fw ctl multik stop    -> stop CoreXL instance 2

# fw ctl multik stop   -> The last instance cannot be disabled:-)

 

You can activate it again per:

# fw ctl multik start

 

Conclusion:
CoreXL 0 cannot really be deactivated under R80.10+:-)
