Figure 1-1 An application diagram of auto-negotiation transmission rate 

 

 

As shown in 

 the network card transmission rate of the server group (Server 1, Server 2, and 

Server 3) is 1000 Mbps, and the transmission rate of GigabitEthernet 2/0/4, which provides access to 

the external network for the server group, is 1000 Mbps too. If you do not specify an auto-negotiation 

range, the transmission rate on GigabitEthernet 2/0/1, GigabitEthernet 2/0/2 and GigabitEthernet 2/0/3 

through negotiation with the servers is 1000 Mbps, which may cause congestion on the egress port 

GigabitEthernet 2/0/4. To solve the problem, you can specify the auto-negotiation transmission rate on 

GigabitEthernet 2/0/1, GigabitEthernet 2/0/2, and GigabitEthernet 2/0/3 to 100 Mbps. 

Follow these steps to configure an auto-negotiation transmission rate:

If you repeatedly use the speed and the speed auto commands to configure the transmission rate 

on a port, only the latest configuration takes effect. 

 

You can use the storm suppression function to limit the size of a particular type of traffic (currently 

broadcast, multicast and unknown unicast traffic) on a per-port basis in Ethernet port view or port group 

view.  

In port or port group view, you set the maximum broadcast, multicast or unknown unicast traffic allowed 

to pass through a port or each port in a port group. When the broadcast, multicast, or unknown unicast
