display car statistics interface

Function

The display car statistics interface command displays the committed access rate (CAR) statistics on an interface.

Format

display car statistics interface { interface-type interface-number | interface-name } [ vlan vlan-id | vid vid | ce-vid ce-vid | vid vid ce-vid ce-vid | pe-vid pe-vid ce-vid ce-vid ] { inbound | outbound }

display car statistics interface { interface-type interface-number | interface-name } { dscp dscpvalue | 8021p 8021pvalue } inbound

Parameters

Parameter	Description	Value
vlan vlan-id	Specifies a VLAN ID. You must specify a VLAN ID to view CAR statistics on a Layer 2 interface.	The value is an integer in the range 1 to 4094.
vid vid	Indicates the external VLAN ID of CAR statistic packets which pass through a special interface.	The value is an integer in the range 1 to 4094.
ce-vid ce-vid	Indicates the CE VLAN ID (internal tag value) of CAR statistic packets which pass through a special interface.	The value is an integer in the range 1 to 4094.
pe-vid pe-vid	Indicates the PE VLAN ID (external tag value) of CAR statistic packets which pass through a special interface.	The value is an integer in the range 1 to 4094.
inbound	Displays CAR statistics on an interface in the inbound direction.	-
outbound	Displays CAR statistics on an interface in the outbound direction.	-
interface interface-name	Specifies the interface name.	-
interface interface-type interface-number	Specifies the interface type and interface number.	-
dscp dscpvalue	Specifies the DSCP value.	The value is an integer that ranges from 0 to 63 .
8021p 8021pvalue	Specifies the 8021p value.	The value is an integer that ranges from 0 to 7 .

Usage Guidelines

Usage Scenario

To check whether CAR takes effect, run the display car statistics interface command to check the CAR statistics on an interface.

Statistics on a Layer 3 interface include statistics on its sub-interfaces.

Precautions

You must specify a VLAN ID to query CAR statistics on a Layer 2 interface.

This command displays only the statistics about CAR configured using the car, multicast-suppression, broadcast-suppression, and unknown-unicast-suppression commands.

Example

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

# Display the CAR statistics in the inbound direction with specified dscp.

Committed Access Rate	Indicates the CAR.
Conform Action	Indicates the conformed actions.
Yellow Action	Indicates the action taken for yellow packets.
Exceed Action	Indicates the action taken for packets whose transmission rate exceeds the CAR.
Last 30 seconds passed rate	Indicates the rate of the packets passing in the last 30 seconds.
Last 30 seconds dropped rate	Indicates the rate of the packets dropped in the last 30 seconds.
Passed	Total number of passed packets from the time when the first packet is passed to the time when the command is executed, in packets and bytes, respectively.
Dropped	Total number of discarded packets from the time when the first packet is discarded to the time when this command is executed, in the unit of packets and bytes.
