Re: [vpp-dev] FW: Bug: DHCP Client not sending DHCP REQUEST using VPP v22.02
Yes, you are right. The show error counters.
vpp# show errors
Count Node Reason
Severity
34dhcp-client-process DHCP discover packets sent
error
Count Node Reason
Severity
357dhcp-client-process DHCP discover packets sent

Do you know how to read in detail about this errors?
Can I read something from these files?
ls l /var/run/vpp/
api.sockcli.sockmemif.sock stats.sock
I captured fresh eventlogs and pcap trace again.

The dhcp client has a number of “show error” counters. Do you see any of the
error counters increasing?
The packet trace I’d like to see would be from “trace add 1000” …
“show trace max 1000” or similar. The pcap trace implies that the dhcp offer
packets are dropped, but we need to work out why…

There is something in the DHCP OFFER the client does not like and moves back to
new DHCP session. Or the DHCP OFFER never made it to the client.

I do see DHCP Offer in the packet tracer from the Server which I have set up on
the other side.
But VPP does not send any DHCP Request out, instead I always see that VPP
continuously keeps sending DHCP Discovery.
I have attached tx and rx pcap trace in my prevous email.

Hello,
I am testing DHCP client feature from VPP stack (v22.02) onto our system.
My setup is: I run k8s cluster on x86 system in which I have a pod which uses
VPP stack and it accesses physical NIC interface using DPDK and SR-IOV. There
are two physical interfaces which we use in VPP, one of them is with static IP
(eno2) and other one with as DHCP client (eno1).
I expect this interface shall act as a DHCP Client and we run a DHCP server on
the other end of the system. But unfortunately, the VPP does not send any DHCP
REQUEST. It keeps sending DHCP DISCOVERY every interval. It receives a DHCP
Offer.
But VPP does not send further DHCP REQUEST to the DHCP server. I do not expect
that it is a problem from lower layer and it should be an issue from VPP side.
Please let me know if I need to enable any extra plugin other than the ones in
the attached file.
I attached pcap file recorded vpp trace of tx and rx.
Our versions are currently as follows:
-> DPDK 22.03
-> VPP 22.02

[vpp-dev] FW: Bug: DHCP Client not sending DHCP REQUEST using VPP v22.02
Hello,
I am testing DHCP client feature from VPP stack (v22.02) onto our system.
My setup is: I run k8s cluster on x86 system in which I have a pod which uses
VPP stack and it accesses physical NIC interface using DPDK and SR-IOV. There
are two physical interfaces which we use in VPP, one of them is with static IP
(eno2) and other one with as DHCP client (eno1).
I expect this interface shall act as a DHCP Client and we run a DHCP server on
the other end of the system. But unfortunately, the VPP does not send any DHCP
REQUEST. It keeps sending DHCP DISCOVERY every interval. It receives a DHCP
Offer.
But VPP does not send further DHCP REQUEST to the DHCP server. I do not expect
that it is a problem from lower layer and it should be an issue from VPP side.
Please let me know if I need to enable any extra plugin other than the ones in
the attached file.
I attached pcap file recorded vpp trace of tx and rx.
Our versions are currently as follows:
-> DPDK 22.03
-> VPP 22.02
-> VPP library 22.02
Version Information attached.
