In the Layer 2 multicast scenario, if the corresponding VLANIF interface is created and the Layer 3 multicast function is configured on the VLANIF interface, the switch forwards multicast data based on Layer 3 multicast forwarding entries in the same way as when both Layer 2 and...

All forwarding operations on Catalyst 9000 series switch are performed using S-VLAN and not C-VLAN information because the VLAN ID is mapped to the S-VLAN on ingress. Note When you configure features on a port for VLAN mapping, you always use th...
1.Specify 1.1.1.1/24 and 1.1.2.1/24 as the gateway IP address for Host A and Host B, respectively. 2.On the device, create VLAN-interface 2 and configure the IP address as 1.1.1.1/24, which is the same as the gateway ...
1. Layer 3 Switch: A VLAN is designed to segment broadcast domains at layer 2, meaning a switch will only allow traffic within the same VLAN (it won't pass traffic from one VLAN to another VLAN). However, there are options available to route traffic from one VLAN to another VLAN. A ...
Figure 1.Example of a Service Provider with Layer 2 VPN Service All forwarding operations on Catalyst 9000 series switch are performed using S-VLAN and not C-VLAN information because the VLAN ID is mapped to the S-VLAN on ingress.
1. Layer 3 Switch: A VLAN is designed to segment broadcast domains at layer 2, meaning a switch will only allow traffic within the same VLAN (it won't pass traffic from one VLAN to another VLAN). However, there are options available to route traffic from one VLAN to another VLAN. A ...
VLAN and Trunking Fundamentals | VLAN和Trunk的原理 Automatic negotiation to determine whether a port will be an access port or a trunk port is risky because an attacker could potentially negotiate a trunk with a switch; then the attacker could directly access any available VLANs simply by illegal...
Layer 3 switches are generally more expensive due to the added routing functionality, but they offer better scalability and control over larger networks. Use Case For simple LANs with no need for inter-VLAN communication, a Layer 2 switch is sufficient and cost-effective. ...
Check whether there is Layer 3 multicast configuration in the corresponding VLANIF interface view. In the Layer 2 multicast scenario, if the corresponding VLANIF interface is created and the Layer 3 multicast function is configured on the VLANIF interface, the switch forwards ...
