3.8 Configuration Examples

This section provides examples for configuring auto-negotiation and port isolation.

3.8.1 Example for Configuring the Auto-Negotiation Rate Range

This configuration example applies to the auto-negotiation mode. When data has multiple
inbound interfaces but only one outbound interface, you can set the auto-negotiation rate range
for the inbound interfaces to prevent congestion on the outbound interface.
Networking Requirements
As shown in
Ethernet0/0/2 of RouterA and access the Internet by using an uplink.
PC1, PC2, and PC3 work at a rate of 100 Mbit/s, and Ethernet0/0/3 connecting RouterA and the
Internet also works at a rate of 100 Mbit/s. If the auto-negotiation rate range is not specified, the
rate negotiated between the interfaces (Ethernet0/0/0, Ethernet0/0/1, and Ethernet0/0/2) and the
PCs (PC1, PC2, and PC3) is 100 Mbit/s. This may cause congestion on outbound interface
Ethernet0/0/3.
