What is a 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 protocol is used in VLAN trunk?
VTP
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks (VLAN) on the whole local area network. To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks.
What is a VLAN used for?
VLANs allow network administrators to automatically limit access to a specified group of users by dividing workstations into different isolated LAN segments. When users move their workstations, administrators don’t need to reconfigure the network or change VLAN groups.
What are two types of ports for VLANs?
Different Types of Switch Ports
- Access Ports. An access port belongs to and carries the traffic of only one VLAN.
- Trunk Ports. A trunk port carries the traffic of multiple VLANs and by default is a member of all VLANs in the VLAN database.
- Tunnel Ports.
What is a dynamic VLAN?
Dynamic VLANs are MAC address-based. You can define a VLAN by specifying the MAC address of the members you want to include. Dynamic VLANs provide flexibility and do not require mapping to the physical ports where the device is physically connected to the switch.
How many VLANs are there?
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).
When would you use a VLAN trunk?
With VLAN trunking, it’s possible to extend a VLAN across the network. When you implement multiple VLANs across a network, trunk links are necessary to ensure that VLAN signals remain properly segregated for each to reach their intended destination.
What is VLAN in simple words?
Stands for “Virtual Local Area Network,” or “Virtual LAN.” A VLAN is a custom network created from one or more existing LANs. It enables groups of devices from multiple networks (both wired and wireless) to be combined into a single logical network.
What are the types of VLAN ports?
There are 5 main types of VLANs depending on the type of the network they carry:
- Default VLAN –
- Data VLAN –
- Voice VLAN –
- Management VLAN –
- Native VLAN –
