  • The access layer switches are configured the same

    The access layer switches are configured the same

    The access layer consists of layer 3 switches, which take routed and switched data packets from the distribution switches and then route them to the access devices in subnets. The access devices in subnets can be modems, video display units, receiver audio phones . Access layer switches are primarily deployed in Layer 2 mode in the data center. In a properly designed network, LAN switches are responsible for directing and control-ling the data flow at the access layer to networked resources. This is largely due to how port-level settings interact with physical capabilities and peer devices. Key factors. Is it wrong to configure access layer switches as layer 3 instead of layer2 as all the latest 9200 9309 series essential switches are layer 3 by default ie ip routing is enabled hence i define interface vlan ip for all vlans being spanned through network and ip route to core for routing instead of. The access layer is where endpoints (such as phones, laptops, video-conferencing sets, printers, IoT sensors, IP cameras, and servers) are primarily connecting to the network.
