Traffic Limit and Line Rate

In this example, the intranet is connected through 100M ports between departments, and the wage server is connected through the port GigabitEthernet7/0/1 (subnet address 129.110.1.2). For the wage server, the inbound traffic is limited to 20M and the outbound traffic to 20M, on average. Those packets exceeding the threshold are labeled with priority level 4.

Only the 20-Port 10/100/1000BASE-T and 20-Port 1000BASE-X-SFP I/O modules support further processing for excessive traffic.

Only the 20-Port 10/100/1000BASE-T and 20-Port 1000BASE-X-SFP I/O modules support line rate setting.

For the 20-Port 10/100/1000BASE-T and 20-Port 1000BASE-X-SFP I/O modules, the adjustment step for both traffic limit and line rate is 1 Mbps, but for other interface units, the adjustment step for traffic limit is 64 Kbps.
