Mirroring group 1:

    Type: Local

    Status: Active

    Mirroring port:

        FortyGigE1/0/1  Inbound

    Monitor port: FortyGigE1/0/2

Table 1 Command output

Field

Description

Mirroring group

Number of the mirroring group.

Type

Type of the mirroring group:

·     Local.

·     Remote source.

·     Remote destination.

Status

Status of the mirroring group:

·     Active—The mirroring group has taken effect.

·     Incomplete—The mirroring group configuration is not complete and does not take effect.

Sampler

Sampler name.

·     If the mirroring group failed to use the sampler, this field displays sampler-name (failed).

·     If no sampler is configured, this field is not displayed.

Mirroring port

Source port.

Mirroring CPU

Source CPU.

Monitor port

Destination port.

 

mirroring-group

Use mirroring-group to create a mirroring group.

Use undo mirroring-group to delete mirroring groups.

Syntax

mirroring-group group-id { local [ sampler sampler-name ] | remote-destination | remote-source }

undo mirroring-group { group-id | all | local | remote-destination | remote-source }

Default

Parameters

group-id: Specifies a mirroring group ID. The value range for this argument is 1 to 15.

local: Specifies local mirroring groups.

remote-destination: Specifies remote destination groups.

remote-source: Specifies remote source groups.

all: Specifies all mirroring groups.

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

Usage guidelines

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

Examples

# Create local mirroring group 1.

<Sysname> system-view

[Sysname] mirroring-group 1 local

mirroring-group mirroring-cpu

Use mirroring-group mirroring-cpu to configure source CPUs for a mirroring group.

Use undo mirroring-group mirroring-cpu to remove source CPUs from a mirroring group.

Syntax

In standalone mode:

mirroring-group group-id mirroring-cpu slot slot-number-list { both | inbound | outbound }

undo mirroring-group group-id mirroring-cpu slot slot-number-list

In IRF mode:

mirroring-group group-id mirroring-cpu chassis chassis-number slot slot-number-list { both | inbound | outbound }

Parameters

group-id: Specifies a mirroring group by its ID. The value range for this argument is 1 to 15.

Usage guidelines

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

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

An aggregation member port cannot be configured as a monitor port.

On an IRF fabric, the following rules apply:

·     For local port mirroring to take effect on F series cards of an IRF fabric, the mirroring source ports and the monitor ports must reside on the same IRF member device.

·     When Layer 3 remote port mirroring is configured on H series cards of an IRF fabric, the mirrored packets are rate-limited when the following conditions exist:

¡     The mirroring source ports and monitor ports are not on the same IRF member device.

¡     The monitor ports are unreachable or the destination of the original packets is the local IRF fabric.

Usage guidelines

CAUTION

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 default settings of the port are automatically restored. You cannot configure other features on the 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 cannot change the duplex mode, MDI settings, or speed for a reflector port.

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

For mirroring to take effect on F series cards of an IRF fabric, the following ports must reside on the same IRF member device:

·     For local port mirroring with multiple monitoring devices implemented through a remote probe VLAN, the mirroring source ports and the reflector port.

·     For Layer 2 remote port mirroring in reflector port mode, the mirroring source ports and the reflector port on the source device.

Examples

# Create remote source group 1. Configure FortyGigE 1/0/1 as its reflector port in system view.

<Sysname> system-view

[Sysname] mirroring-group 1 remote-source

[Sysname] mirroring-group 1 reflector-port fortygige 1/0/1

Parameters

group-id: Specifies a mirroring group by its ID. The value range for this argument is 1 to 15.

vlan-id: Specifies a VLAN by its ID.

Usage guidelines

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

Usage guidelines

Use the ports in a monitoring group only for flow mirroring, so the data monitoring device receives and analyzes only the mirrored traffic.

Examples

# Create monitoring group 1 and assign Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 to it.

<Sysname> system-view

[Sysname] monitoring-group 1
