4 Port Speed Limitation

4.1 Overview of the port speed limitation function

The ESML6-P3 series supports port transmitting rate limitation, services limitation and
broadcast limitation. These all belong to the traffic limitation function which allows:

A maximum of 26 ports’ speed limitation at one time.

A specific limit or user typing

A speed limitation range

A minimum limitation value: 64Kbps

A max limitation value: 100*100Kbps (100M port)

A speed limitation accuracy

For different accuracy in the different speed limitation ranges, see below:

Example

Input value: 65K

64K to 1.792M

64K

-32K to 32K

Actual value:64K

Input value: 127K

Actual value:128K

Input value: 2.3M

2M to 100M

1M

-0.5M to 0.5M

Actual value:2M

Input value: 2.8M

Actual value:3M

The Control Interface supports the speed limitation control using the Console port, Telnet
and the WEB interface.

Limitation mode:

Speed limitation is divided into two groups: Group 1 and Group 2. The message first
accesses Group 1 which is specialized in the limitation of service messages and is fixed
for all ports. Group 2 is used to set limitations to other messages and it is also fixed to all
ports.

Default configuration:

Service messages: unicast, multicast

Broadcast messages: broadcast, reserved multicast, unknown unicast, unknown
multicast.

Support separated limitation of service messages and broadcast messages

Support overall speed limitation for transmitting messages.
