UNDERSTANDING ACCESS POINTS ROUTERS AND SWITCHES

Too many access layer switches

Too many access layer switches

Having too many switches in a network can contribute to switch overload, but it is not the sole cause. Switch overload is typically caused by a combination of factors, including the amount of data being transmitted, the capacity of the switch, and the network design. In this article, we'll walk through: The goal is not to declare "Layer 2 bad, Layer 3 good," but to give you a practical mental model: When should I stop stretching VLANs and start routing closer to the edge? 1. How We Ended Up with VLAN Trunks Everywhere For years, the default access design has. In a 2 or 3 layer model, if you have more than 4 aggregation/distribution layer switches but only 4 uplink ports on access layer switches, how do you go about connecting the two layers? Everything is fine if you only have 4 or less aggregation/distribution switches but any more and you can no. For the followings topologies, they explain that : A limitation of those solutions is that it is optimal for networks where each access layer VLAN can be constrained to a single access switch.

Preventing Unauthorized Access to Fiber Optic Routers

Preventing Unauthorized Access to Fiber Optic Routers

Pro Tips for Fortifying Your Fiber Network Enable WPA3 Encryption: Newer routers support this unhackable standard (skip WPA2!). Fiber optic cables offer superior protection against electromagnetic eavesdropping compared to copper, making passive monitoring significantly more challenging. Attackers with specialized tools can: Physically access unsecured junctions or cabinets. Network access control plays a significant role in maintaining the security of fiber optic networks, with measures. Top Picks: Ubiquiti UniFi Dream Machine Pro: Combines firewall, IDS/IPS, and VPN in one. Threat actors use botnets to conduct Distributed Denial of Service (DDoS) attacks, which will overwhelm your server with internet traffic and disrupt your ability to provide essential business operations and services.

Layer 2 ACL Application of Access Layer Switches

Layer 2 ACL Application of Access Layer Switches

ACLs can be configured to match packets based on Layer 2 MAC, Layer 3 IP or Layer 4 TCP/UDP parameters. We have 3850 switches in our environment which are acting as a layer 2 only with a trunk port configured to the core (6500). Access Control Lists (ACLs) are crucial for enhancing network security, especially on Layer 2 switches configured with extended access lists using source and destination criteria.

Industrial switches can be fixed

Industrial switches can be fixed

In most cases, a limit switch is replaced rather than repaired, especially in industrial environments where reliability and downtime are critical. While some high-end modular switches allow for actuator or contact block replacement, many are sealed or riveted and not designed for. When problems arise, it's crucial to have a systematic approach to quickly diagnose and resolve issues. As the linchpin of connectivity, they support a myriad of devices and systems that are integral to the day-to-day functioning of industrial processes.
