Configuration Task List For Vlans - Dell Force10 S4810P Configuration Manual

• The VLAN protocol identifier identifies the frame as tagged according to the IEEE 802.1Q
specifications (2 bytes).
• Tag Control Information (TCI) includes the VLAN ID (2 bytes total). The VLAN ID can have 4,096
values, but 2 are reserved.
Note: The insertion of the tag header into the Ethernet frame increases the size of the frame to more than
the 1518 bytes specified in the IEEE 802.3 standard. Some devices that are not compliant with IEEE 802.3
may not support the larger frame size.
Information contained in the tag header allows the system to prioritize traf f ic and to forward information to
ports associated with a specific VLAN ID. Tagged interfaces can belong to multiple VLANs, while
untagged interfaces can belong only to one VLAN.

Configuration Task List for VLANs

This section contains the following VLAN configuration tasks:
• Create a port-based VLAN
• Assign interfaces to a VLAN
• Assign an IP address to a VLAN
• Enable Null VLAN as the Default VLAN
Create a port-based VLAN
The Default VLAN as VLAN 1 is part of the system startup configuration and does not require
configuration. To configure a port-based VLAN, you must create the VLAN and then add physical
interfaces or port channel (LAG) interfaces to the VLAN.
To create a port-based VLAN, use the following command in the CONFIGURATION mode:
Command Syntax
interface vlan
vlan-id
1056
| Virtual LANs (VLAN)
(mandatory)
(optional)
(optional)
Command Mode Purpose
CONFIGURATION Configure a port-based VLAN (if the vlan-id is different
from the Default VLAN ID) and enter INTERFACE
VLAN mode.
After you create a VLAN, you must assign interfaces in
Layer 2 mode to the VLAN to activate the VLAN.
