display interface brief main non-unicast

Function

The display interface brief main non-unicast command displays brief information about all interfaces on a device, including the physical status and protocol status of the interfaces, latest inbound and outbound bandwidth usage, and the number of sent and received error packets.

Usage Guidelines

Usage Scenario

Before you monitor interface status or locate an interface fault, run the display interface brief main non-unicast command to view the status of and statistics on the interface. The command output helps you diagnose faults.

Compared with the display interface command, the display interface brief main non-unicast command provides briefer interface information, focusing on the most important information.

Perform any of following operations based on the interface status and statistics:

If the interface is Down, check whether the link connection is correct or whether interface negotiation succeeds.
Interface statistics reflect traffic received and sent. If the interface has a lot of error statistics, check whether the interface is attacked or whether the link quality is stable.

Follow-up Procedure

Run the reset counters interface command to delete interface statistics displayed using the display interface brief command.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display information about broadcast and multicast packets on all main interface on a device.

**Table 1** Description of the **display interface brief main non-unicast** command output
Item	Description
Interface	Name and number of an interface. If logical interfaces have member interfaces, these member interfaces are displayed in alphabetical order. The first character of each line in the output is indented by two spaces. Interface types are the same as those displayed in the display interface brief command output.
PHY	Physical status of the interface.
Protocol	Link layer protocol status of the interface.
InBroad	Number of broadcast packets received by an interface.
OutBroad	Number of broadcast packets sent by an interface.
InMulti	Number of multicast packets received by an interface.
OutMulti	Number of multicast packets sent by an interface.
InUti	Average inbound bandwidth usage of this interface in the last 300 seconds. Average inbound bandwidth usage in the last 300 seconds = Average inbound rate in the last 300 seconds/Interface bandwidth. When the average inbound bandwidth usage is lower than 0.01% and this interface is receiving traffic, value 0.01% is displayed. When the interface bandwidth becomes lower, bandwidth usage may become 100% because adjusting the traffic volume is delayed. Hyphens (--) indicates that this type of interface does not support the display of bandwidth usage. You can run the set flow-stat interval command to change the interval at which traffic statistics are collected.
OutUti	Average outbound bandwidth usage in the last 300 seconds. Average outbound bandwidth usage in the last 300 seconds = Average outbound rate in the last 300 seconds/Interface bandwidth. When the average outbound bandwidth usage is lower than 0.01% and this interface is sending traffic, value 0.01% is displayed. When the interface bandwidth becomes lower, bandwidth usage may become 100% because adjusting the traffic volume is delayed. Hyphens (--) indicates that this type of interface does not support the display of bandwidth usage. You can run the set flow-stat interval command to change the interval at which traffic statistics are collected.
