example:
5496 port a1 connects to 2910 port 1
5496:
vlan 1
untag a1
vlan 2
tag a1
vlan 3
tag a1
vlan 4
tag a1
2910:
vlan 1
untag 1
vlan 2
tag 1
vlan 3
tag 1
vlan 4
tag 1
switch-to-switch ports requiring vlans to pass between the switches, require the ports to be 'tagged' in the vlans.
end-device ports (like computers/printers) would be 'untagged' in the appropriate vlan.
