Hi,

I try to setup a test bed using PS "Testpoint in container" on Nexus 9300v. I installed testpoint as described in guide and I'm able to run it.

In container I see three namespaces and default is "management":

root@switch#ip netns

management (id: 1)

default (id: 0)

vnicBank (id: 200)

 

The problem is for configuration purposes it's perfectly fine to have "management" as default. But I want to test Data interfaces and they are only accessible in "default" namespace.

 

I can run any command in "default" namespace with:

"ip netns exec default twping 1.1.1.1" for example

 

but I'm afraid that pscheduler knows nothing about that command and will try to run just simple "twping/owping/iperf/..."

without any "netns" options. One idea maybe to make a "wrapper" between "tools" and "ip netns exec " but

So far I have limited experience with PS, I will appreciate if someone could point me to the right way to use testpoint setup on Nexus. I saw Thomas Costello's presentation on youtube where he described such environment but without technical details.

 

Kind regards,

Oleg
