Usage Guidelines

Usage Scenario

The display interface null command displays the status of a null interface. The interface status information includes: the physical status, link layer protocol status, description, MTU, current system time, last time statistics about the null interface are cleared, incoming and outgoing packet rates in bit/s and pps, total numbers of packets and bytes received and sent by the null interface, and percentages of the rates for receiving and sending packets to the total bandwidth.

Precautions

There is only one null interface, namely, NULL 0.

Example

# Display the status of Null 0 interface.

<Huawei> display interface null 0
NULL0 current state : UP

Item

Description

NULL0 current state

Physical status of the null interface.

The physical status of the null interface is always Up.

Line protocol current state

Link layer protocol status of the interface. The protocol status of the null interface is always Up.

Description

Description of the interface, which can be set by using the description command.

Route Port,The Maximum Transmit Unit is 1500

The MTU is 1500 bytes.

Internet protocol processing

Whether Internet protocol processing is enabled.
  • enabled: The Internet protocol processing is enabled.
  • disabled: The Internet protocol processing is disabled.

Physical is NULL DEV

The interface is null.

Current system time

Current system time.

Last 300 seconds input rate

Last 300 seconds output rate
