If you use the group-member interface-type
interface-start-number to interface-type
interface-end-number command to add multiple
ports in batch to the specified port group, make
sure all these ports are of the same type and on the
same interface card, and the interface-end-number
argument must be greater than the
interface-start-number argument.
Setting speed options for auto negotiation on an Ethernet
interface
Speed auto negotiation enables an Ethernet interface to negotiate with its peer for the highest speed that
both ends support by default. You can narrow down the speed option list for negotiation.
Figure 1 Speed auto negotiation application scenario
As shown in Figure 1, all ports on the device are operating in speed auto negotiation mode, with the
highest speed of 1000 Mbps. If the transmission rate of each server in the server cluster is 1000 Mbps,
their total transmission rate exceeds the capability of port GigabitEthernet 1/0/4, the port providing
access to the Internet for the servers.
To avoid congestion on GigabitEthernet 1/0/4, set 100 Mbps as the only option available for speed
negotiation on port GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3. As a
result, the transmission rate on each port connected to a server is limited to 100 Mbps.
