The point was that you can do a type of traffic and security engineering by limiting where certain VLANs are allowed to go. If you didn't want VLANs 2 and 20 to pass through SW2, it is possible. However, it is not necessarily a best practice design. Like in this case, it is not...
Therefore, I am a bit rusty concerning Rapid-PVST+ and Cisco best practices with regard to vlan 1 and how it should be treated. If I recall, a security-related best practice is to change the native vlan on a dot1Q trunk that is running rapid-PVST+ from vlan 1 to an otherwise unus...
Because VLANs are a common security target, designing VLANs with security in mind is being proactive. Here are some best practices to use before you create the first VLAN on a switch. VLAN Design Guidelines (3.3.2.1) Cisco switches have a factory configuration in which default VLANs are pre...
This chapter describes the security implications of a Private VLAN (PVLAN) and of a native VLAN. When hosts are segregated into VLANs, they are also placed into separate IP subnets. Service providers often find this arrangement to be problematic, especially when there is need for additional secu...
(choose two) A、 Change the native VLAN to an unused VLAN ID B、 Assign all access ports to VLANS other than the native VLAN C、 Configure an ACL to prevent traffic from changing VLANS. D、 Configure dynamic ARP inspection E、 Configure port security...
VLANs also bring security benefits to larger networks by allowing greater control over which devices have local access to each other. Wi-Fi guest networks are often implemented usingwireless access pointsthat support VLANs. PM Images/Getty Images ...
The third article provides a highly valuable insight into industry best practices for enhancing VLANsecurity.

Best practices suggest that the native and management VLANs be moved to another distinct VLAN and that unused switch ports be moved to a “black hole” VLAN for increased security. The switchport access vlan command is used to create a VLAN on a switch. After creating a VLAN, the next ...
simulated environment as if they exist in a single LAN and are sharing a single broadcast and multicast domain. VLAN are implemented to achieve scalability, security and ease of network management and can quickly adapt to changes in network requirements and relocation of workstations and server ...
This update reflects our commitment to staying current with industry trends and best practices to deliver a seamless and future-proof SD-WAN experience. Talking about security, this is also an opportunity to mention that flexiWAN was lately examined by one of the largest and well known security ...
