What is encapsulation dot1q?

IEEE802.1Q, often referred to as DOT1Q or 1Q, is the networking standard that supports virtual LANs (VLANs) on an IEEE 802.3 Ethernet network. It is the most widely used encapsulation method for VLAN tagging. It is also referred to as the Ethernet standard.

Which is the default mode in switch ports?

The default switchport mode for newer Cisco switch Ethernet interfaces is dynamic auto. Note that if two Cisco switches are left to the common default setting of auto, a trunk will never form. switchport mode dynamic desirable: Makes the interface actively attempt to convert the link to a trunk link.

What happens to switch ports after the VLAN to which they are assigned is deleted?

What happens to switch ports after the VLAN to which they are assigned is deleted? The ports are disabled. The ports are placed in trunk mode. The ports are assigned to VLAN1, the default VLAN.

What is 802.1Q used for?

802.1Q tunneling enables service providers to use a single VLAN to support customers who have multiple VLANs, while preserving customer VLAN IDs and keeping traffic in different customer VLANs segregated. A port configured to support 802.1Q tunneling is called a tunnel port.

What is the purpose of 802.1Q tagging?

The 802.1Q tagging protocol allows the Ethernet frame size to increase by four bytes to a range of 68 to 1522 bytes. This size increase is due to the insertion of a four-byte VLAN tag into the frame. The tags, which include a VLAN Identifier (VID), are attached to each Ethernet frame by MAC address.

What is 802.1Q trunking protocol?

VLAN Trunking (802.1Q) allows physical network interfaces in a computing environment to be shared, or multi-homed. Network devices on the network then only interact with packets that have the correct tags. This allows multiple different logical networks to run on the same cable and switch infrastructure.

What are the 3 types of VLANs?

Types of VLAN

  • Management VLAN.
  • Data VLAN.
  • Voice VLAN.
  • Default VLAN.
  • Native VLAN.

What is the highest VLAN number?

Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).

What is standard VLAN?

IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual LANs (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.

What are three primary benefits of using VLANs?

VLANs provide a number of advantages, such as ease of administration, confinement of broadcast domains, reduced broadcast traffic, and enforcement of security policies.

How do I turn on trunking switch port?

To enable trunk links, configure the ports on either end of the physical link with parallel sets of commands. To configure a switch port on one end of a trunk link, use the switchport mode trunk command. With this command, the interface changes to permanent trunking mode.

What type of VLAN is used to separate?

It is common practice to separate voice and management traffic from data traffic. A data VLAN, is sometimes referred to as a user VLAN. Data VLANs are used to separate the network into groups of users or devices.
