Chapter 1. Commands for Network Port Configuration 11

www.qtech.ru

 Command: port-scan-mode {interrupt | poll}

 no port-scan-mode

 Function: Configure the scan mode of the port as “interrupt” or “poll”, the no

command restores the default scan mode.

 Parameter: interrupt: the interrupt mode; poll: the poll mode.

 Command Mode: Global Mode.

 Default: Poll mode.

 Usage Guide: There are two modes that can respond up/down event of the port. The

interrupt mode means that interrupt hardware to announce the up/down change, the

poll mode means that software poll can obtain the port event, the first mode is rapid. If

using poll mode, the convergence time of MRPP is several hundred milliseconds, if

using interrupt mode, the convergence time is less than 50 milliseconds.

 Notice: The scan mode of the port usually configured as poll mode, the interrupt mode

is only used to the environment of the good performance, but the security of the poll

mode is better.

 Example: Configure the scan mode of the port as interrupt mode.

 Switch(config)#port-scan-mode interrupt

1.1.11 port-status query interval

 This command is not supported by the switch.

1.1.12 rate-violation

 Command: rate-violation <200-2000000> [recovery <0-86400>]

 no rate-violation

 Function: Set the max packet reception rate of a port. If the rate of the received packet

violates the packet reception rate, shut down this port and configure the recovery time,

the default is 300s. The no command will disable the rate-violation function of a port.

 The rate-violation means the port received all packets rate (the number of the received

packets per second), do not distinguish the packet type.

 Parameters: <200-2000000> the max packet reception rate of a port, the unit is

packets/s.

 <0-86400>: The interval of recovery after shutdown, the unit is s.

 recovery: After a period of time the port can recover shutdown to up again. <0-86400>

is the timeout of recovery. For example, if the shutdown of a port happens after the

packet reception rate exceeding the limit, the port will be up again when the user-

defined timeout expires. The default timeout is 300s, while 0 means the recovery will

never happen.

 Command Mode: Interface Mode

 Default: There is no control operation for rate-violation.

 Usage Guide: This command is mainly used to detect the abnormal port flow. For

example, when there are a large number of broadcast messages caused by a loopback,
