Dear Anthony, Please check the bond interface to see if the active slaves count has any positive number using show bond. Since you didn’t configure LACP on VM2, I believe you’ve not gotten any active slave in VPP. Your solution is to configure a bond interface in VM2 using mode 4 (I believe) if it is running linux.
vpp# sh bond sh bond interface name sw_if_index mode load balance active slaves slaves BondEthernet0 3 lacp l2 2 2 vpp# Alternately, you can replace lacp from VPP with xor as shown below when you create the bond interface if you don’t want to bother with lacp on VM2. create bond mode xor Steven From: <[email protected]> on behalf of Anthony Linz <[email protected]> Date: Friday, February 22, 2019 at 11:11 PM To: "[email protected]" <[email protected]> Subject: Re: [vpp-dev] Bond interface won't respond ping #vnet #vpp Dear Steven Thank you very much for your quick and nice response. I suppose the beginning of my question might misguide you. Let me clear my test scenario: I have a Virtual Machine (VM1) which runs VPP and has an interface called GigabitEthernet0/8/0. I have another Virtual Machine (VM2) that it's interface (eth1) is in the same Kernel bridge as GigabitEthernet0/8/0 (and does not run VPP). So that I am able to ping GigabitEthernet0/8/0 easily (from VM2). After creating a Bond interface (in VM1) with LACP mode (and also setting the state up and giving it IP address) and binding GigabitEthernet0/8/0 to the Bond interface I have neither ping of GigabitEthernet0/8/0 nor Bond interface (from VM2). I traced packets and It seems Bond interface is able to receive ARP packets (and learn it), however is not able to respond back to it. So I went ahead and set arps (for VM2) so that it started to send ICMP packets and again Bond interface (in VM1) was able to receive it but could not respond to it. So my question really is: 1) Why don't Bond interface is not able to respond to either ARP or ICMP packets? 2) Is my config incomplete? (or maybe wrong) 3) Is it logical to ping a Bond Interface? Thank you again for your response, -- Anthony
