Hi,
i am having a issue with VPP running on RH8.2 with version 20.05.1.
There are 4 commands that I am trying to run from my application (using
vppcli), fairly straight forward. the Trace.Writeline function is just a
utility to print out the trace.
what I see is the ret val is 256 indicating system command did not get
executed properly. however the same command when i type it manually ,
works perfectly fine.. Not sure what is wrong. I am logged in as root and
running the process using "./a.out" (manually) as a root.
Could anyone suggest anything else to check apart from switching to VPP API
to configure interfaces/add routes etc? we had few issues with vpp api/vcl
libraries and have not decided to pursue vpp - api for now, so vppctl is
the only option. Alternative is to write a ipaddr.txt file and put it in
startup.conf -> which will do the trick. However I want to do it from
application. is there special flag in vpp.log to enable that can give
information. i could not find anything useful in vpp.log
string s1("vppctl create sub-interfaces
HundredGigabitEthernet12/0/1 501");
string s2("vppctl set interface state HundredGigabitEthernet12/0/1
up");
string s3("vppctl set interface state
HundredGigabitEthernet12/0/1.501 up");
string s4("vppctl set interface ip address
HundredGigabitEthernet12/0/1.501 2001:5b0:ffff:501:b883:31f:19e:8879/64");
int ret;
ret = system(s1.c_str());
Trace.WriteLine(TraceConstants::Configuration, "Cmd: ", s1, ", ret
= ", ret);
ret = system(s2.c_str());
Trace.WriteLine(TraceConstants::Configuration, "Cmd: ", s2, ", ret
= ", ret);
ret = system(s3.c_str());
Trace.WriteLine(TraceConstants::Configuration, "Cmd: ", s3, ", ret
= ", ret);
ret = system(s4.c_str());
Trace.WriteLine(TraceConstants::Configuration, "Cmd: ", s4, ", ret
= ", ret);
my startup.conf file:
unix {
nodaemon
log /var/log/vpp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
gid vpp
}
