Before touching anything in Windows, it is essential that the switch is configured to support VLANs and, if applicable, aggregation (static or LACP), correctly assigning the ports that go to the server. Otherwise, the NIC equipment may be up, but the traffic will not flow. This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, VLANs, VLAN aggregation, MUX VLAN, VLAN termination, Voice VLAN, VLAN mapping, QinQ, GVRP, VCMP, STP/RSTP/MSTP, VBST, SEP, RRPP, ERPS, LBDT, and Layer 2 protocol transparent. Most Nexus-based data center designs today use the concept of Cisco® virtual device context (VDC), which allows the creation of separate control-plane domains in a single switch. From a forwarding perspective, vPC is deployed in the context of a VDC. In other words, vPC as a feature and the. Link aggregation is the process of combining multiple links so that the links function as a single link with higher bandwidth. The sub-VLANs are addressed from the same IP subnet and share a default gateway address, thereby reducing the. Switches and servers must match in aggregation modes, allowed VLANs, and trunk configuration. VTP and EtherChannel facilitate centralized management and link aggregation in medium and large networks. If you work with physical servers and managed switches or virtualization environments, sooner or. As devices are added to a small network, more switch ports are needed to connect those devices to the network.
