port-observing dest-mac

Function

The port-observing dest-mac command configures the destination MAC address for mirrored packets on the observing port.

The undo port-observing dest-mac command cancels the destination MAC address for mirrored packets on the observing port.

By default, no destination MAC address is configured for mirrored packets on the observing port.

Format

port-observing dest-mac dest-mac-address

undo port-observing dest-mac dest-mac-address

Parameters

Parameter	Description	Value
dest-mac-address	Specifies a destination MAC address.	The value is in the format of H-H-H. Each H is a 4-digit hexadecimal number, such as 00e0. If an H contains less than 4 bits, 0s are padded ahead. For example, if an H is e0, it is displayed as 00e0 in the MAC address.

Usage Guidelines

Usage Scenario

The command can also be used in SIG mirroring scenarios. When the port mirroring function is configured, the SIG imports traffic to the mirrored port and copies the traffic into multiple flows using the port mirroring function. After mirrored packets are sent to the observing port, the observing port removes Layer 2 headers of the original packets and encapsulates the specified destination MAC address into the packets for subsequent forwarding.

This command is used to configure the destination MAC address for mirrored packets on the observing port.

If this command is required on the observing port, the port-mirroring without-linklayer-header command must be configured on the corresponding mirrored port to configure the mirrored port to remove Layer 2 headers from packets.

Prerequisites

An interface has been configured as the observing port.

Precautions

The port-observing dest-mac and port-observing pop-label commands are mutually exclusive.

Example

# Configure the destination MAC address 00e0-fc12-3456 for mirrored packets on GE 0/1/8.
