Devices that can filter network frames include routers, switches, and firewalls. Routers filter frames based on IP addresses and routing protocols, while switches can filter frames at the data link layer using MAC addresses. Firewalls provide a more comprehensive filtering capability by examining both frame and packet data to enforce security policies. Additionally, intrusion detection systems (IDS) and intrusion prevention systems (IPS) can also filter frames for security purposes.

How does CDP gather the neighbor devices network address information?
CDP is a Cisco proprietary protocol; it only works between Cisco devices. If CDP is enabled on a Cisco network device, it will regularly send frames with information about itself out its interfaces.CDP is a Cisco proprietary protocol; it only works between Cisco devices.

By default access points send beacon frames every how many ms?
By default, access points typically send beacon frames every 100 milliseconds (ms). This interval can vary depending on the specific configuration of the wireless network and the settings of the access point. Beacon frames are essential for maintaining the network, allowing devices to discover and connect to the wireless network.

What is a possible cause of runt Ethernet frames when a switch is being used?
A possible cause of runt Ethernet frames when a switch is being used is a mismatch in network configurations, such as different duplex settings between devices. This can lead to collisions and truncated frames. Additionally, hardware issues like faulty network interface cards (NICs) or cabling problems can also contribute to the generation of runt frames, as they can disrupt the normal transmission of data packets.
Are frames in the network layer?
No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.
What is the function of routing in the network OSI layer3?
The whole point of the network layer, and layer 3 devices, is to move packets between separate networks. Layer 2 devices on the other hand (switches), only move frames using only the data link layer between hosts in that same network. Without layer 3 devices (routers or gateways), there could be no communication between separate interconnected groups of computers.
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
What is bridge connection?
A bridge connection refers to a network architecture that links multiple devices within a local area network (LAN), allowing them to communicate and share resources. It operates at the data link layer (Layer 2) of the OSI model, using MAC addresses to forward data frames between segments. This connection helps reduce network traffic and improve efficiency by dividing larger networks into smaller, manageable segments. Bridges can also filter and manage traffic to enhance overall network performance.
What is frame discuss its classification?
In the context of computer networking, a frame is a data unit transmitted over a computer network. Frames are classified based on the protocol layer they belong to, such as data link layer frames (e.g., Ethernet frames), network layer frames (e.g., IP packets), and transport layer frames (e.g., TCP segments). Each type of frame serves a specific purpose in transmitting and delivering data across the network.
Explain each type of network devices with its function?
Computer network devices also known as communication devices and they constitute a data communication network. These devices are routers, switches, hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals and transceivers. In an Ethernet or WAN network, the data communication cannot be performed without these devices. Being an IT professional or a network administrator, you must have the good understanding of these devices.
What is the purpose of native vlan?
The purpose of a native VLAN is to handle untagged traffic on a trunk port in a network switch. When a switch receives frames that are not tagged with a VLAN identifier, it associates those frames with the native VLAN, typically the default VLAN (VLAN 1). This allows for proper segregation and management of traffic in a VLAN environment, ensuring that untagged frames are processed appropriately within the network. Additionally, the native VLAN helps maintain compatibility with devices that do not support VLAN tagging.
