So I have two Linux devices, connected by a single Ethernet cable. I am trying to understand how VLANs work and experimenting a bit.
On device 1, which has an IP address of 10.210.3.1 and 2 Ethernet ports, there is a VLAN configuration of:
- VLAN ID 200 which is set as the Management VLAN, port membership is
for both Ethernet ports VLAN ID 201, port membership on port 1 (not set as Management VLAN)
VLAN ID 202, port membership on port 1 (not set as Management VLAN)
Device 1 and 2 are connected by an Ethernet cable on port 1.
On device 2, I have added a VLAN 201 with IP address of 10.210.3.2 (the interface is enp0s3.201)
When I try to ping from device 2 to device 1, I can see the 802.1Q information (I have set the pings to come from interface used by the VLAN). Device 1 shows ARP broadcasts being received from device 2 however it does not reply to it.
What am I doing wrong?

It might help if you filled in some of the blanks.  (1) What Linux are you using?  (2) How many interfaces does device 2 have?  (3) What are all the IP addresses?  (The outputs fromipconfig -amight be useful.) Please do not respond in comments; edit your question to make it clearer and more complete. P.S. A possibility: look closely at all your netmask values (I’ve seen that cause trouble in situations somewhat similar to this).
