What is a port based VLAN?
A port-based VLAN configuration lets you assign ports on the switch to a VLAN. The number of VLANs is limited to the number of ports on the switch. In a basic port-based VLAN configuration, ports with the same VLAN ID are placed into the same VLAN. One port can be a member of multiple VLANs.
Which is the 802 specification for VLANs?
IEEE 802.1Q
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 two types of ports for VLANs?
Common Switch Port Types on Network Switches When the data switch resides in a VLAN, there may be three common switch port types: access port, trunk port and hybrid port. An Ethernet interface can function as a trunk port, an access port or a hybrid port.
What is protocol based VLAN?
A protocol-based VLAN processes traffic based on protocol. You can use a protocol-based VLAN to define filtering criteria for untagged packets. Each group has a one-to-one relationship with a VLAN ID, can include one to three protocol definitions, and can include multiple ports.
What is the difference between an access port vs a trunk port?
What is the difference between an access port and a trunk port? An access port is a connection on a switch that transmits data to and from a specific VLAN. A trunk port allows you to send all those signals for each switch or router across a single trunk link.
What does QinQ stand for?

What is the purpose of the native VLAN in 802 Q trunking?
VLANs keep traffic from different networks separated when traversing shared links and devices within a topology. This process, also known as VLAN tagging, is invaluable to limiting broadcast network traffic and securing network segments.
What is the difference between ISL and 802.1 Q?
802.1q encapsulation inserts a 4 byte tag into original frame and FCS (Frame Check Sequence) is re-calculated. ISL uses more processor cycles than 802.1q because of the modification of the header and recalculation of FCS.
What are the types of VLAN ports?
Types of Virtual LAN (VLAN)
- Default VLAN – When the switch initially starts up, all switch ports become a member of the default VLAN (generally all switches have default VLAN named as VLAN 1), which makes them all part of the same broadcast domain.
- Data VLAN –
- Voice VLAN –
- Management VLAN –
- Native VLAN –
What are three ports on a computer?

- PS/02.
- Serial Port.
- Parallel Port.
- Ethernet.
