VLAN Trunking
and E automatically allow frames with VLAN group tags 1 and 2 (groups that
are unknown to those switches) to pass through their VLAN trunking ports.
◆
VLAN trunking is mutually exclusive with the "access" switchport mode (see
"Adding Static Members to VLANs" on page
on an interface, then that interface cannot be set to access mode, and vice
versa.
◆
To prevent loops from forming in the spanning tree, all unknown VLANs will be
bound to a single instance (either STP/RSTP or an MSTP instance, depending on
the selected STA mode).
◆
If both VLAN trunking and ingress filtering are disabled on an interface, packets
with unknown VLAN tags will still be allowed to enter this interface and will be
flooded to all other ports where VLAN trunking is enabled. (In other words,
VLAN trunking will still be effectively enabled for the unknown VLAN).
