Hi Team,
I am facing an issue when I try to set the interface to DHCP Client on
VPP-20.01 with worker thread enabled in the startup.conf.
Environment Used:
1. Vpp 20.01 running on a Ubuntu 16.01 VM.
2. Two CPU cores allocated
cat /proc/cpuinfo | grep processor
processor : 0
processor : 1
Startup.conf
----------------------------------------------------------------
unix {
nodaemon
interactive \
cli-listen /run/vpp/cli.sock
log /tmp/vpp.log
full-coredump
}
api-trace {
on
}
socksvr {
default
}
cpu {
*main-core 0*
*corelist-workers 1*
}
dpdk {
dev 0000:02:01.0
}
socksvr { socket-name /tmp/vpp-api.sock}
------------------------------------------------------------------------
Running VPP Debug CLI:

Can someone please help me understand and fix this issue?
