We have an ESXi 6.5 server running vm's with the following networking conviguration:
vswitch0 - phyiscal nic vmnic0, port group Management Network with VLAN ID 0
vswitch1 - physical nic vmnic1, port groups (PG-VLAN700 with VLAN ID 700, PG-VLAN200 with VLAN ID 200, and PG-ALL_VLANs-Trunk with VLAN ID 4095)
vswitch2 - physical nic vmnic2, port group PG-VLAN300 with VLAN ID 300
The guests are RHEL 6/7
Issue 1: VM has 2 interfaces both on PG-VLAN200. Interface 1 works but interface 2 is never accessable, can't ping the IP on the interface event though it shows as up.
Issue 2, which may be related to issue 1: VM has 4 interfaces, 2 on PG-VLAN200, 2 on PG-VLAN300. I started with just 2 interfaces on PG-VLAN200 and it was working. As soon as I added interfaces 3 & 4 to the VM and assigned them to PG-VLAN300 and rebooted, all 4 interfaces stopped working.
I have tested that PG-VLAN300 works on another VM that just has 1 interface assigned to PG-VLAN300.
I hope that someone can point me in a direction why these are not working correctly.
Thanks
Robert
Do you have 2 default gateways configured? Please show an output of "route ip".
Hello,
Regarding issue 1: first, what about the default gateway of two interfaces ? kindly clarify the needs of two interfaces with same VLAN in a VM.
For issue 2: you said "I started with just 2 interfaces on PG-VLAN200 and it was working" how did you test that were working ? and what is the difference between this case and issue 1 ?
When you add another network for any computer, i recommend to help traffic using some static route. please i prefer to more clarify your test.
Please consider marking this answer "CORRECT" or "Helpful" if you think your question have been answered correctly.
