The Cisco Nexus 2148T forwards all traffic to parent Cisco Nexus 5000 Series Switches over 10 Gigabit Ethernet uplinks. Depending on the number of server ports and uplinks used, the Cisco Nexus 2148T FEX can support oversubscription ratios ranging from 1:1 to 4.8:1. Passing all traffic to the parent switch allows all traffic to be shaped according to policies established on the Cisco Nexus 5000 Series switch with a single point of management.
