Steven,
vppctl does not have a ping command I am on version 20.5 (may be I did not
compile this option?) Also not sure how to parse this trace output.
When I ping System B from System A and run the trace on SystemB I get the
following output:
$ sudo vppctl show trace
------------------- Start of thread 0 vpp_main -------------------

Subject: Re: [vpp-dev] Need help with setup.. cannot ping a VPP interface.
Manoj,
Because system B is running VPP, you can’t initiate the ping from system B in
Unix Shell. Kernel does not have that interface and IP address anymore for you
to do the ping. You have to start the ping from vppctl if you want to do the
ping from system B running VPP.
When you do the ping from system A, type
vppctl show error
vppctl show interface
may help you to find out why the packet got dropped or if it arrives at all to
VPP. If that still does not help, take the trace from VPP. Something like this
vppctl trace add dpdk-input 100
ping 10.1.1.10 <-- ping rom system A
vppctl show trace
Honestly, I’ve never worked with a Broadcom NIC which you are using.
tx burst function: bnxt_xmit_pkts
rx burst function: bnxt_recv_pkts
May the force be with you.

Subject: Re: [vpp-dev] Need help with setup.. cannot ping a VPP interface.
Dave/Steven,
I set the netmask on both sides to 255.255.255.0 and here is how I setup the ip
address on the 2 servers. System-B has ip address set using vppctl and system-A
was setup using ifconfig, as below. The link is up on both enp2s0f1np1 on
System A and bnxt0 on System B. VPP version used is 20.05.
Also on System B where I setup 10.1.1.10 as the IP address on the VPP interface
bnxt0, I was not able to ping that IP from the host system (System B). Please
see below towards the end where this ping fails.
(Also, I setup the exact same physical interfaces without using VPP and was
able to ping each other.)

+check hardware addresses with “show hardware”, to make sure you’ve configured
the interface which is actually connected to the peer system / switch...

Please correct the subnet mask first.

Subject: [vpp-dev] Need help with setup.. cannot ping a VPP interface.
Hello,
I am very new to VPP and I am having trouble pinging the vpp interface. I have
a system with ip address 10.1.1.10 set up using a VPP interface, and I have
another system with ip address 10.1.1.11 setup with no VPP. Both systems are
connected though a switch.
If I do not use VPP I am able to ping each other, but when I use VPP to
configure one of the IPs I am unable to ping.
I know this might be a very basic setup issue. Could someone please point me in
the right direction. I have read through
