Chapter 2 Network configuration
212859-A
In
Figure 12
, untagged incoming packets are assigned directly to VLAN 2
(PVID = 2). Port 5 is configured as a tagged member of VLAN 2, and port 7
is configured as an untagged member of VLAN 2.
Figure 12 Port-based VLAN assignment
As shown in
Figure 13
, the untagged packet is marked (tagged) as it leaves the
switch through port 5, which is configured as a tagged member of VLAN 2. The
untagged packet remains unchanged as it leaves the switch through port 7, which
is configured as an untagged member of VLAN 2.
