HSR VLAN Tests
Enable HSR offloads on all 3 boards

Test ping/iperf between a pair of Nodes (A ↔ B, B ↔C, A ↔ C) on both direct and forwarding path by plugging and unplugging appropriate LAN cables

1) Add multiple VLAN interfaces on Node A and Node C

On Node A

# ip link add link hsr0 name hsr0.2 type vlan id 2

# ifconfig hsr0.2 192.168.20.10

# ip link add link hsr0 name hsr0.3 type vlan id 3

# ifconfig hsr0.3 192.168.30.10

# ip link add link hsr0 name hsr0.4 type vlan id 4

# ifconfig hsr0.4 192.168.40.10

# ip link add link hsr0 name hsr0.5 type vlan id 5

# ifconfig hsr0.5 192.168.50.10

On Node C

# ip link add link hsr0 name hsr0.2 type vlan id 2

# ifconfig hsr0.2 192.168.20.50

# ip link add link hsr0 name hsr0.3 type vlan id 3

# ifconfig hsr0.3 192.168.30.50

# ip link add link hsr0 name hsr0.4 type vlan id 4

# ifconfig hsr0.4 192.168.40.50

# ip link add link hsr0 name hsr0.5 type vlan id 5

# ifconfig hsr0.5 192.168.50.50

2) Now ping on the VLAN and non VLAN interfaces on Node A and Node C; 
  

ping 192.168.10.50

or

ping 192.168.20.50

or

ping 192.168.30.50

or

ping 192.168.40.50

or

ping 192.168.50.50

While the ping is executing, disconnect LAN cable between Node A and C; Node B would forward packets even if it is not part of VLAN domains

Repeat the test with Node C as iperf Server and Node A  iperf client for both VLAN and non VLAN interfaces

3) Add few VLAN interfaces on Node B

# ip link add link hsr0 name hsr0.2 type vlan id 2

# ifconfig hsr0.2 192.168.20.30

# ip link add link hsr0 name hsr0.4 type vlan id 4

# ifconfig hsr0.4 192.168.40.30

Ping VLAN (VID = 2 and VID = 4)and non VLAN interfaces between Node A and Node B; Ping on both direct and forward path should be functional

Now ping VLAN (VID = 3, VID = 5) interfaces between Node A and Node C; Ping on both direct and forward path should be functional.

4) Delete VLAN interface on Node B

# ip link delete hsr0.2

Now test VLAN, non VLAN interfaces between Node A and Node B , Node A and Node C;

Note: Once VLAN interfaces are added, inorder to re-run the hsr_setup.sh script, all the added VLAN interfaces must be deleted
