Configuring OSPF? First, interfaces need IP addresses. This example shows how to configure IP addresses on G0/1 and G0/2 interfaces. Remember subnetting! #OSPF #Networking
VLANs need trunk ports to carry tagged traffic. Trunking the port and matching the encapsulation type (dot1Q) allows inter-VLAN communication. A forgotten trunk can block ping! #Networking #VLAN #CCNA
Cat 5E is outdated; run Cat 6 for better performance. VLANs are crucial for managing bandwidth and preventing network congestion, especially during imaging processes. Ignoring this can cripple network speeds. #NetworkTips #VLANs
Starting a business? Business cards + warehouse visits get the ball rolling. For small networks, a 16-port switch is usually plenty, but always use CAT6 cabling. Mixed CAT5/6 environments are a recipe for disaster. #NetworkSetup #ITBusiness
Don't mix Cat5e with Cat6 cabling. Cat6 provides better performance with less crosstalk. VLANs segment networks to reduce broadcast traffic and improve bandwidth. Ignoring this leads to network bottlenecks. #Networking #Cat6
Cybersecurity shouldn't be about security, but deterrence. For every security measure, there's a workaround. Passwords need to be long—at least 21 characters—and complex. Deterrence is key. #Cybersecurity #CyberDeterrence
Running anything less than CAT6 today is a mistake. CAT5e might seem okay, but it loses gigabit speed after 200 feet. CAT6 is the standard for a reason—invest in the right cable. #CAT6 #Networking
Think someone's throwing a LAN party on your network? Port security can help! It dynamically learns MAC addresses and sticks them to the table, preventing unauthorized devices from connecting. #CyberSecurity #NetworkSecurity
Someone's gonna plug a rogue switch into the wrong port. Spanning Tree Protocol (STP) is enabled to prevent the nightmare. Implement BPDU Guard on your ports to prevent Shadow IT attacks. #Networking #Cybersecurity
Dictionary words are terrible passwords. NIST now favors shorter, less complex passwords due to user habits. Smart cards & key fobs? The IT dept should manage them, and track sign-in/out! #CyberSecurity #PasswordTips
