Default Vlan Behavior - Dell PowerEdge M420 Configuration Manual

Default VLAN Behavior

One VLAN exists on the PowerConnect M6220, M6348, M8024, and
M8024-k switches by default. The VLAN ID is 1, and all ports are included in
the VLAN as access ports, which are untagged. This means when a device
connects to any port on the switch, the port forwards the packets without
inserting a VLAN tag. If a device sends a tagged frame to a port, the frame is
dropped. Since all ports are members of this VLAN, all ports are in the same
broadcast domain and receive all broadcast and multicast traffic received on
any port.
When you add a new VLAN to the VLAN database, no ports are members.
The configurable VLAN range is 2–4093. VLAN 4094 and 4095 are reserved.
VLAN 4095 is designated as the
to 4095 will effectively shut the port down because frames are not forwarded
in either direction.
Ports in trunk and access mode have the default behavior shown in Table 21-2
and cannot be configured with different tagging or ingress filtering values.
When you add a VLAN to a port in general mode, the VLAN has the behavior
shown in Table 21-3.
