CONFIGURATION

1.1 Commands for Ethernet Port Configuration

1.1.1 bandwidth

 Command: bandwidth control <bandwidth> {transmit | receive | both}

 no bandwidth control

 Function: Enable the bandwidth limit function on the port; the no command disables

this function.

 Parameter: <bandwidth> is the bandwidth limit, which is shown in kbps ranging

between 1-1000000K; both refers to the bandwidth limit when the port receives and

sends data, receive refers to the bandwidth limit will only performed when the switch

receives data from out side, while transmit refers to the function will be perform on

sending only.

 Command Mode: Port Mode.

 Default: Bandwidth limit disabled by default.

 Usage Guide: When the bandwidth limit is enabled with a size set, the max bandwidth

of the port is determined by this size other than by 10/100/1000M. If [both | receive |

transmit] keyword is not specified, the default is both.

 Note: The bandwidth limit can not exceed the physic maximum speed on the port. For

example, an 10/100M Ethernet port can not be set to a bandwidth limit at 101000K (or

higher), but applicable on a 10/100/1000 port working at a speed of 100M. If the actual

bandwidth is not a integral multiple of chip bandwidth granularity, it will be modified

automatically. For example, a chip bandwidth granularity is 64K, but the input

bandwidth is 50, the bandwidth will be modified as 64K.

 Example: Set the bandwidth limit of 1/0/1-8 port is 40000K.

 Switch(config)#interface ethernet 1/0/1-8

 Switch(Config-If-Port-Range)#bandwidth control 40000 both

1.1.2 clear counters interface

 Command: clear counters [interface {ethernet <interface-list> | vlan <vlan-id> | port-

channel <port-channel-number> | <interface-name>}]

 Function: Clears the statistics of the specified port.

 Parameters: <interface-list> stands for the Ethernet port number; <vlan-id> stands for

the VLAN interface number; <port-channel-number> for trunk interface number;

<interface-name> for interface name, such as port-channel 1.

 Command mode: Admin Mode.

 Default: Port statistics are not cleared by default.

 Usage Guide: If no port is specified, then statistics of all ports will be cleared.
