Usage guidelines

RPR logical interfaces support only local port mirroring and can only be configured as source ports for local mirroring groups. For more information about RPR logical interfaces, see High Availability Configuration Guide.

Parameters

group-id: Specifies a mirroring group by its number in the range of 1 to 4. The specified mirroring group must already exist.

interface-type interface-number: Specifies a port by its type and number.

Usage guidelines

You can configure reflector ports only for remote source groups.

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.

You can configure a port as a reflector port only when the port is operating with the default duplex mode, speed, and MDI settings. You cannot change these settings for a reflector port.

In an IRF 3 system, PEXs do not support reflector ports for Layer 2 remote port mirroring. For more information about IRF 3 and PEXs, see Virtual Technologies Configuration Guide.

Examples

# Create remote source group 1. Configure GigabitEthernet 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 gigabitethernet 1/0/1

This operation may delete all settings made on the interface. Continue? [Y/N]: y

# Create remote source group 2. Configure GigabitEthernet 1/0/2 as its reflector port in interface view.

mirroring-group remote-probe vlan

Use mirroring-group remote-probe vlan to specify a VLAN as the remote probe VLAN for a mirroring group.

Use undo mirroring-group remote-probe vlan to remove a remote probe VLAN from a mirroring group.

Syntax

mirroring-group group-id remote-probe vlan vlan-id

undo mirroring-group group-id remote-probe vlan vlan-id

Default

No remote probe VLAN is configured for a mirroring group.

Parameters

group-id: Specifies a mirroring group by its number in the range of 1 to 4. The specified mirroring group must already exist.

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

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

Flow mirroring commands

The flow mirroring commands are available on both Layer 2 and Layer 3 Ethernet interfaces. The term "interface" in this chapter collectively refers to these two types of interfaces. You can use the port link-mode command to configure an Ethernet port as a Layer 2 or Layer 3 interface (see Layer 2—LAN Switching Configuration Guide).

mirror-to

Use mirror-to to configure a mirroring action for a traffic behavior.

Use undo mirror-to to delete a mirroring action.

Syntax

mirror-to { cpu | interface interface-type interface-number }

undo mirror-to { cpu | interface interface-type interface-number }

Default

No mirroring action is configured for a traffic behavior.
