Parameters

inbound: Specifies packets received by mirroring sources.

outbound: Specifies packets sent by mirroring sources.

cir committed-information-rate: Specifies the committed information rate in the range of 1000000 to 100000000 kbps.

cbs committed-burst-size: Specifies the committed burst size in the range of 1000 to 2000000 bytes.

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot.

Usage guidelines

In the port mirroring scenario, the monitor port might monitor the traffic of multiple mirroring sources at the same time. If the speed of packets received or sent by the mirroring sources are too high, the monitor port might be congested and drop packets. In this case, you can configure this feature on the device where the mirroring sources reside. This feature rate-limits mirrored packets and avoid congestion on the port mirroring network.

Examples

# Configure CAR for the packets received by mirroring sources of port mirroring in the specified slot as follows: set the CIR to 1000000 kbps and set the CBS to 16385 bytes.

<Sysname> system

[Sysname] mirroring-group car inbound cir 1000000 cbs 16385 slot 3

Parameters

group-id: Specifies a mirroring group by its number. The specified mirroring group must already exist. The value range for this argument is 1 to 64.  

pop-label: Pops out all MPLS labels of packets mirrored to an interface. If you do not specify this keyword, the MPLS labels of mirrored packets are not popped out. Support for this keyword depends on the device model.

Usage guidelines

You can configure monitor ports only for local mirroring groups and remote destination groups.

Follow these guidelines when you configure the MPLS label removal feature by using the pop-label keyword:

·     You can specify the pop-label keyword only when specifying a monitor port for a local mirroring group.

·     You can also enable a flow mirroring destination interface to remove MPLS labels for mirrored packets by specifying the pop-label keyword in the mirror-to interface command. However, the flow mirroring destination interface removes MPLS labels for mirrored packets whether or not the pop-label keyword is specified if the following conditions are met:

¡     The QoS policy that uses the traffic behavior where the flow mirroring destination interface is specified is applied to the outbound direction of a port.

¡     The outbound traffic of the port is also a mirroring source of a local mirroring group.

¡     The pop-label keyword is specified for the monitor port of the local mirroring group.

·     MPLS labels are removed for mirrored packets sent to destinations specified in a QoS policy for NetStream flow mirroring if the following conditions are met:

¡     The QoS policy is applied to the outbound direction of a port.

¡     The outbound traffic of the port is also a mirroring source of a local mirroring group.

¡     The pop-label keyword is specified for the monitor port of the local mirroring group.

·     To change the status of the MPLS label removal feature for a monitor port, first remove the monitor port configuration, and then reconfigure the monitor port.

Do not enable the spanning tree feature on the monitor port of a mirroring group.

For a Layer 2 or Layer 3 aggregate interface configured as the monitor port of a mirroring group, do not configure its member ports as source ports of the mirroring group.

Use a monitor port only for port mirroring, so the data monitoring device receives and analyzes only the mirrored traffic.

The member port of an existing mirroring group cannot be configured as a monitor port.

The source port of an existing mirroring group cannot be configured as a monitor port.

The member port of an aggregate interface cannot be configured as a monitor port.

CAUTION: ·     The port to be configured as a reflector port must be a port not in use. Do not connect a network cable to a reflector port. ·     When a port is configured as a reflector port, the port restores to the factory default settings. You cannot configure other features on a reflector port. ·     If an IRF port is bound to only one physical interface, do not configure the physical interface as a reflector port. Otherwise, the IRF might split.

 

You can configure reflector ports only for remote source groups.

You can configure a port as a reflector port only when the port is operating with the default setting of the following parameters:

·     Duplex mode.

·     Speed.

·     MDI settings.

Parameters

group-id: Specifies a mirroring group by its number. The specified mirroring group must already exist. The value range for this argument is 1 to 64.

vlan-id: Specifies a VLAN by its ID.

Usage guidelines

To implement Layer 2 remote port mirroring with the configurable reflector port method, make sure the remote probe VLAN ID is different from any subinterface IDs configured for the following interfaces:

·     Physical interfaces on the card where the reflector port resides.

·     Layer 3 aggregate interfaces that contain physical interfaces on the card where the reflector port resides.

You can configure remote probe VLANs only for remote source groups and remote destination groups.

When a VLAN is configured as a remote probe VLAN, use the VLAN for port mirroring exclusively.

The remote mirroring groups on the source device and destination device must use the same remote probe VLAN.

Only a static VLAN that already exists can be configured as a remote probe VLAN. A VLAN can be configured as the remote probe VLAN for only one mirroring group.

To delete a VLAN that is configured as a remote probe VLAN, remove the remote probe VLAN configuration first.

Examples

# Create remote source group 1 and configure VLAN 10 as its remote probe VLAN.

<Sysname> system-view

[Sysname] mirroring-group 1 remote-source

[Sysname] mirroring-group 1 remote-probe vlan 10

# Create remote destination group 2 and configure VLAN 20 as its remote probe VLAN.

Parameters

interface-type interface-number: Mirrors traffic to an interface specified by its type and number.

sampler sampler-name: Specifies a sampler by its name. The sampler-name argument is a case-insensitive string of 1 to 31 characters.

pop-label: Pops out all MPLS labels of packets mirrored to an interface. If you do not specify this keyword, the MPLS labels of mirrored packets are not popped out. Support for this keyword depends on the device model.

Usage guidelines

You can execute this command multiple times for a traffic behavior to mirror traffic to different interfaces.

A sampler selects a packet from sequential packets. Flow mirroring uses a sampler to limit the volume of traffic to be mirrored. It supports using a sampler that has not been created. If you configure multiple samplers for a mirroring action, the most recent configuration takes effect. For more information about samplers, see Network Management and Monitoring Configuration Guide.

Follow these guidelines when you configure MPLS label removal in a traffic behavior to be used by a QoS policy for flow mirroring:

·     A flow mirroring destination interface removes MPLS labels for mirrored packets whether or not the pop-label keyword is specified in the mirror-to interface command if the following conditions are met:

¡     The QoS policy that uses the traffic behavior where the flow mirroring destination interface is specified is applied to the outbound direction of a port.

¡     The outbound traffic of the port is also a mirroring source of a local mirroring group.

¡     The pop-label keyword is specified for the monitor port of the local mirroring group.

·     MPLS labels are removed for mirrored packets sent to destinations specified in a QoS policy for NetStream flow mirroring if the following conditions are met:

¡     The QoS policy is applied to the outbound direction of a port.

¡     The outbound traffic of the port is also a mirroring source of a local mirroring group.

¡     The pop-label keyword is specified for the monitor port of the local mirroring group.

Usage guidelines

If you execute this command for a traffic behavior multiple times, the most recent configuration takes effect.

A sampler selects a packet from sequential packets. Flow mirroring uses a sampler to limit the volume of traffic to be mirrored. It supports using a sampler that has not been created. If you configure multiple samplers for a mirroring action, the most recent configuration takes effect. For more information about samplers, see Network Management and Monitoring Configuration Guide.

Examples

# Create traffic behavior 1 and configure the action of mirroring traffic to the specified slot by using sampler samp.
