The answer is "Native VLAN mismatch". The exhibit is unclear and some details are NOT accurate. Accurate exhibit and clear explanation are at https://vceguide.com/what-causes-this-behavior/ Untagged frames are encapsulated with the native VLAN. In this case, the native VLANs are different; so although S1 tags it as VLAN 1, it will be received by S2 as VLAN 2.

Continuing with the answer... Thats why Vlan 2 on SW 2 is the Native VLAN. Just to set it clear.

on the output given it should say "NATIVE VLAN" not "NETWORK VLAN" this displays a false output.
