Network requirements
As shown in Figure 61:
•Server A, Server B, and Server C are connected to GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3 of the switch, respectively. The rates of the network adapters of these servers are all 1000 Mbps.
•The switch connects to the external network through GigabitEthernet 1/0/4 whose speed is 1000 Mbps.
To avoid congestion at the egress port GigabitEthernet 1/0/4, configure the autonegotiation speed range on GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3 as 100 Mbps.
