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.
