Virtual Switch Features

Adding Layer 2 Tunnel Connection as a Virtual Port Member

The term “Adding Layer 2 Tunnel Connection as a Virtual Port Member” refers to a configuration action in network virtualization and tunneling protocols, typically involving Layer 2 (Data Link Layer) tunneling. This process associates the Layer 2 tunnel connection with a specific virtual port.

IPsec Encryption for Layer 2 Tunnels

IPsec encryption for Layer 2 tunnels is a method used to securely transmit Layer 2 data traffic over physical networks. This is typically applied when Ethernet frames need to be encrypted using the IPsec (Internet Protocol Security) protocol to establish a secure connection. It is used in multi-layer networks, remote connections, and data center connections. IPsec encryption enhances tunnel security and provides robust protection against external threats.

Adding Physical Port as a Member

Adding a physical port as a member refers to the process of associating physical network ports with a specific logical network structure (e.g., VLAN, virtual network, etc.) in network configurations, particularly in virtualization and network management systems. This allows network administrators to link physical ports with virtual networks, providing more flexible and controlled traffic management.

IEEE 802.1Q VLAN Untagged Port Assignment for Both Virtual and Physical Ports

An untagged port is a port that carries traffic that is not associated with any VLAN, i.e., traffic without a VLAN tag. It is typically assigned to a single VLAN and does not accept tagged traffic. This port is usually used as an access port and communicates with devices that belong to only one VLAN.

IEEE 802.1Q VLAN Tagged Port Assignment for Both Virtual and Physical Ports

A tagged port carries traffic that includes VLAN tags (802.1Q tags). It can accept data from multiple VLANs, allowing it to transport traffic from more than one VLAN. Tagged ports are typically used as trunk ports, transporting data from multiple VLANs.

IEEE 802.1Q VLAN Hybrid Port Assignment for Both Virtual and Physical Ports

A hybrid port can carry both tagged and untagged traffic simultaneously. It can handle traffic from virtual networks (tagged) as well as from physical devices (untagged). This port typically combines the features of both trunk and access ports, making it compatible with both virtual and physical devices.

VLAN-Supported MAC Table

The VLAN-supported MAC table is a table where a network device (typically a switch) stores the MAC addresses associated with VLANs and makes routing decisions based on this information. The table allows for the correct routing of MAC addresses to the appropriate network segments by associating them with the corresponding VLANs using the IEEE 802.1Q VLAN tagging protocol.

IEEE 802.3ad Link Aggregation Control Protocol (LACP)

IEEE 802.3ad Link Aggregation Control Protocol (LACP) combines multiple physical connections into a single logical connection to improve network performance. This protocol is used for bandwidth expansion, load balancing, and redundancy. LACP automatically aggregates and directs connections to enhance network efficiency and provides administrators with the ability to create reliable and flexible network structures.

Spanning Tree Protocol

Spanning Tree Protocol (STP) is a protocol used to prevent loops in a network. STP ensures that only one path is active when there are multiple paths, preventing data packets from being misrouted. It eliminates redundant paths and offers backup routes in case of connection failures.

Rapid Spanning Tree Protocol

Rapid Spanning Tree Protocol (RSTP) is a faster version of Spanning Tree Protocol (STP). RSTP responds more quickly to changes in network topology, reducing connection downtime and transition times. This protocol prevents loops and quickly activates backup paths, providing a more efficient and faster network management solution compared to STP.

Link Layer Discovery Protocol (LLDP)

Link Layer Discovery Protocol (LLDP) is a protocol used to share connectivity information between devices on the network. LLDP allows devices to exchange information such as port, device name, and software version. This protocol helps in discovering network topology and facilitates monitoring of device connections.

NetFlow Export Service

NetFlow Export Service collects and sends NetFlow data from one device to another. This data is used to monitor network performance, conduct analysis, and detect security threats.

MAC Learning

MAC Learning is the process through which a network device (typically a switch) learns the MAC addresses of devices on the network. The switch analyzes incoming data frames and stores the MAC addresses in a MAC address table. This allows the device to know which device is located on which port, improving the network’s efficiency and accelerating data transmission.
