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.
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.

Parameters
group-id: Specifies a mirroring group by its ID. The value range for this argument is 1 to 16.
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

Parameters
sampler sampler-name: Specifies a sampler by its name. The sampler-name argument is a case-insensitive string of 1 to 31 characters. If you do not specify this option, packets are not sampled, and all matching packets are mirrored.
vxlan: Performs VXLAN encapsulation before performing INT encapsulation for packets to be mirrored to the INT processor. For more information about VXLAN, see VXLAN Configuration Guide or EVPN Configuration Guide.
Usage guidelines
A sampler selects a packet from sequential packets. Flow mirroring uses the sampler to limit the volume of traffic to be mirrored. Flow mirroring 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.
To enable INT in a VXLAN or EVPN network, you must configure the VTEP as an INT entry node and specify the vxlan keyword when configuring the action of mirroring traffic to the INT processor.

# Create traffic behavior 1 and configure the action of mirroring traffic to the INT processor. Specify sampler samp for the mirroring action.

vlan vlan-id: Specifies a VLAN by its VLAN ID in the range of 1 to 4094 for the mirrored packets.
vrf-instance vrf-instance-name: Specifies a VPN instance by its name, a case-sensitive string of 1 to 31 characters. The mirrored packets will be forwarded based on the routing table of the specified VPN instance.
destination-mac mac-address: Specifies the destination MAC address for mirrored packets sent to the interface. The mac-address argument is in the format of H-H-H. If you do not specify this option, the device uses the destination IP address to dynamically get the destination MAC address for the mirrored packets.
reflector-port interface-type interface-number: Specifies a reflector port by its type and number.
strip-vlan vlan-id: Specifies a VLAN where mirrored packets are broadcast by its ID in the range of 1 to 4094.
Usage guidelines
You can execute the mirror-to interface interface-type interface-number command multiple times for a traffic behavior to mirror traffic to different interfaces.
To mirror traffic to the specified interface, use the mirror-to interface interface-type interface-number command.
To mirror traffic to interfaces based on routes matching the specified destination IP address, use the mirror-to interface destination-ip destination-ip-address source-ip source-ip-address command. When receiving packets that meet the flow mirroring criteria, the device performs the following tasks:
1. Encapsulates the packets based on the configured encapsulation parameters, including the source and destination IP addresses.
2. Searches the routing table for routes matching the configured destination IP address.
If ECMP load-balancing is configured, multiple matching ECMP routes might be found for the specified destination IP address.
3. Sends the mirrored packets out of the output interfaces in the matching routes to the final destination.
If a selected output interface goes down, the device will send the mirrored packets out of another interface based on the routing metric recalculations.
If you do not specify a VLAN for the mirrored packets destined to a VLAN interface, the device encapsulates the packets as follows:
¡ The device determines whether to encapsulate a VLAN ID for the packets based on the VLAN settings for the Layer 2 Ethernet interface associated with the VLAN interface.
¡ To encapsulate a VLAN ID, the device uses the VLAN ID of the VLAN interface to encapsulate the packets.
When you use syntax 3 to mirror traffic to an interface, the device copies packets received on the mirroring sources to the destination interface. Then, the destination interface sends the mirrored packets to the specified reflector port, and the reflector port broadcasts the mirrored packets within the specified VLAN. This syntax is applicable only when the mirrored packets are VLAN-tagged and these packets must be sent out of the device untagged.
When you use syntax 3, the specified mirroring destination interface and reflector port must be assigned to a mirroring-type service loopback group. For more information about service loopback groups, see service loopback group configuration in Layer 2—LAN Switching Configuration Guide.
When you specify the vxlan parameter, you must also set the destination-port destination-port-value parameter to the default value 4789 for the VXLAN encapsulation to take effect. This rule applies only on the SH interface modules.
When the outgoing interface corresponding to the destination IP encapsulated for mirrored packets is a Layer 3 Ethernet subinterface, the VLAN to which the Layer 3 Ethernet subinterface belongs must be the same as the VLAN of mirrored packets.
