Configuring VLANs
661
Default VLAN Behavior
One VLAN is configured on the Dell Networking series 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 with a VLAN ID other than 1, 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 create a new VLAN, all trunk ports are members of the VLAN by
default. The configurable VLAN range is 2–4093. VLANs 4094 and 4095 are
reserved for internal system use.
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 21-6.
