You need to provide them with Layer 3 routing with the fabric. Additionally, if ACI is not built on greenfield, you need tools to interconnect the fabric with legacy networking equipment, stretch Layer 2 segments, and progressively migrate all the physical devices, usually followed by L3 default...
Layer 2 is a physical layer, which is concerned with the physical aspects of a network. It deals with how data travels over a network cable or wireless signal, such as speed and flow control. Layer 3 is a network layer, which is concerned with the logical aspects of a network. It ...
The majority of networks use a mix of Layer 2 and Layer 3 switches to support their operations. Layer 3 switches are more intelligent than Layer 2 switches. Layer 3 switches also feature all the functionality of Layer 2 switches. Therefore, Layer 2 switches are used to provide cheap and...
It is removed from VLAN 1 only when Layer 3 protocols are Up. You can configure Layer 2 and Layer 3 modes of an Ethernet interface in the Ethernet interface view or system view. If the configurations in the two views differ, the latest configuration takes effect....
