Do fiber optic cables for switches have a correct orientation
The connection should be between adapter plate rows with the connector key sharing the same orientation. Because fiber duplex links rely on matched transmit-receive alignment, polarity determines how cables, connectors. Polarity in fiber optic networks refers to the alignment of transmit (Tx) and receive (Rx) signals between interconnected devices. For this signal alignment to work. Key orientation: MTP®/MPO connectors have an extrusion, called a "key", commonly described as key up or key down, that determines the insertion orientation into the adapter. This orientation directly affects the actual positional relationship of the fibers after mating. If the fibers are not crossed in the permanent cable plant, one duplex patch cord in the link needs to be crossed or simplex patch cords can be used and the proper connections made manually.

How many switches are needed for the aggregation layer
An aggregation layer usually comprises a few blocks of two switches in MCLAG. An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. By design, it therefore provides resiliency because it will always be deployed in pairs of switches and comes with a recommendation to deploy only dual hot swappable power supplies and redundant fans in each switch to. This design employs a pair of redundant Cisco Nexus 7010 switches on the aggregation and core layers. Virtual device contexts (VDCs) of the Nexus 7000 switches are utilized in the design to create a pair of aggregation VDC switches and a pair of core VDC switches from two Nexus 7010 switches. Each aggregation switch is physically connected to all edge switches and participates in. Switch aggregation, also known as link aggregation or trunking, is a method used in computer networking to combine (aggregate) multiple network connections in parallel.
