Les tableaux sont assez chiants à présenter sur un petit écran :
les cellules étant en fait souvent bien trop petits pour en mettre 4 ou 5 côte à côte.
Voici une astuce CSS pour linéariser un tableau à une seule entrée :
table, tbody { display: block; }
tr { display: table; }
td { display: table-row; }

- In most routers you cannot have the same subnet address configured on multiple VLANs. I would be very surprised if your default gateway allows you to do something like that. With your current configuration, it appears that traffic coming back from the router will always be classified as being on only one VLAN, either because you have tagging on and router will put on the tag, or you don't have tagging and the incoming port on the switch always classifies the frame as being on the PVID. The simplest way to fix this would be to have 2 subnets (i.e. different interface addresses) for VLAN A and VLAN B on the router, assuming it does VLANs. If it doesn't do VLANs, then you will need to have 2 separate ports on the router, one in VLAN A and one in VLAN B, each configured with the default gateway address to be used for that VLAN. And you would then need to find a way to prevent routing between those VLANs if you don't want the hosts in VLAN A to communicate with the hosts in LANB even via routing.

- Note: Data frames that are tagged with VID 0 are known as priority-tagged data frames
- PVID and Data Flows: In a VBridge, every data frame received on a port is associated with a unique VLAN to enable further processing and forwarding. In case of tagged data frames, the associated VLAN is determined from the VLAN tag. In the case of untagged data frames, the associated VLAN equals the permanent VLAN identifier (PVID) associated with the received port.
- GMRP Garp Multicast Registration Protocol
- GVRP Garp VLAN Registration Protocol. GVRP enables VLAN bridges to dynamically learn their VLAN memberships.
- GARP Generic Attribute Registration Protocol
- Data frame's associated VID is either based on the tag or based the port's PVID.
- PPV Port and Protocol based VLAN
- PPV classification can only be applied to untagged data frames or to priority tagged frames after the removal of the priority tag.
- VPLS Virtual Private Lan Services
- GARP messages are sent to special multicast MAC addresses: GMRP 01:80:c2:00:00:20 and GVRP 01:80:c2:00:00:21
