Troubleshooting Guide

In Full mode, Check connectivity between RE and PFE VMs

Both VMs must be able to reach each other over IP

• RE VM has IP : 169.254.0.2
• PFE VM has IP : 169.254.0.1

From RE VM

vagrant@vqfx-re> ping 169.254.0.1
PING 169.254.0.1 (169.254.0.1): 56 data bytes
64 bytes from 169.254.0.1: icmp_seq=0 ttl=64 time=1.078 ms

From PFE VM

localhost:~$ ping 169.254.0.2
PING 169.254.0.2 (169.254.0.2) 56(84) bytes of data.
64 bytes from 169.254.0.2: icmp_seq=1 ttl=64 time=0.589 ms

RE and PFE VMs are not able to communicate to each other, ping is not working

Check if IPs are properly configured on both side

On RE VM
Interface must be up with IP 169.254.0.2

vagrant@vqfx-re> show interfaces terse | grep em1
em1                     up    up
em1.0                   up    up   inet     169.254.0.2/24

On PFE VM
You need to go in Root and see check if eth1 interface is UP and has IP Root password is no

ocalhost:~$ su - root
Password:
root@localhost:~# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 08:00:27:5c:5c:09
          inet addr:169.254.0.1  Bcast:169.254.0.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe5c:5c09/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:341681 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:74964712 (71.4 MiB)  TX bytes:26401230 (25.1 MiB)

RE and PFE VMs are able to communicate but XE interfaces are not present

This might happen if we are running our of CPU You might want to allocate less CPU resources to PFE VMs
In the Vagrantfile, you can add

            vqfxpfe.vm.provider "virtualbox" do |v|
                v.customize ["modifyvm", :id, "--cpuexecutioncap", "50"]
            end
