Explanation

The command "switchport dot1q ethertype 0800" is not required in this context and doesn't play a role in joining VLANs between two switches. The "switchport dot1q ethertype" command is used to specify a particular EtherType to be used for tagging VLANs. The default EtherType for 802.1Q tagging is 0x8100, which is used to indicate that the frame carries VLAN information. The value 0800 corresponds to the EtherType for IPv4.
