trunk port are forwarded on the native VLAN. Packets received on another

interface belonging to the native VLAN are transmitted untagged on a

General — General ports can act like access or trunk ports or a hybrid of

VLAN membership rules that apply to a port are based on the switchport

mode configured for the port. Table 21-2 shows the behavior of the three

switchport modes.

Table 21-2. Switchport Mode Behavior

VLAN Membership

All VLANs that exist in

the system (default)

As many as desired

When a port is in General mode, all VLAN features are configurable. When

ingress filtering is on, the frame is dropped if the port is not a member of the

VLAN identified by the VLAN ID in the tag. If ingress filtering is off, all

tagged frames are forwarded. The port decides whether to forward or drop the

frame when the port receives the frame.

VLAN Tagging

Dell Networking series switches support IEEE 802.1Q tagging. Ethernet

frames on a tagged VLAN have a 4-byte VLAN tag in the header. VLAN

tagging is required when a VLAN spans multiple switches, which is why trunk

ports transmit and receive only tagged frames.

A stack of switches behaves as a single switch, so VLAN tagging is not

required for packets traversing different stack members.
