traffic generator -recommendations

[Ahiya Zadok]

Hi Jason



Thank you for responding.

So you mean that with parallel processes I could generate requests from
several VLANs simultaneously?

Hello,



I have used a tool called dhtest, I even pushed a change to their github
site.  https://github.com/saravana815/dhtest



I generated about 100,000 mac addresses and built a perl script to call an
arbitrary number of parallel processes.



it worked well.

hi AllI'm planning to implement Kea-dhcp4 to serve around 500 subnets with
5000 devices, I don't think the requests per sec rate will be high, it
MDUs.I'm using FG as a DHCP relay.I’ve performed some functionality tests
and it seems to work fine.I wanted to perform some load tests.I've to
install Kea-admin on ubuntu 18.04 VM and use the perfdhcp app.but I can't
make it quite work. all I see in my DHCP log are "DHCP4_LEASE_ADVERT"
messages and no  "DHCP4_LEASE_ALLOC".and all sent packets are dropped
according to perfdhcp report.I've tried various clients numbers the lower
number of requests and low the rate but it didn't work.any ideas?and dose
any one know if perfdhcp support sending from multiple interfaces?thanks in
