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.

Parameters
cpu
: Mirrors the packets matching the criteria defined in the traffic class to the CPU of the IRF
member device.
interface
interface-type
interface-number
: Mirrors the packets matching the criteria defined in the
traffic class to an interface.
loopback
: Enables loopback for matching packets received on the specified interface. With this
keyword specified, the interface sends the matching packets through the GRE tunnel interface to the
tunnel interface on the destination device. The destination device receives the mirrored packets from
the physical interface of the tunnel interface, and then forwards copies of the packets to the data
monitoring device.
destination-ip
destination-ip-address
: Specifies the destination IP address for the mirrored packets
sent out of the mirroring destination interface.
source-ip
source-ip-address
: Specifies the source IP address for the mirrored packets sent out of
the mirroring destination interface.
dscp
dscp-value
: Specifies the DSCP value for the mirrored packets sent out of the mirroring
destination interface. The value range for the
dscp-value
argument is 0 to 63.
vrf-instance vrf-instance-name
: Specifies the VRF instance by its name for the mirrored packets
sent out of the mirroring destination interface.
vlan
vlan-id
: Specifies the VLAN by its ID for the mirrored packets sent out of the mirroring
destination interface. The value range for the
vlan-id
argument is 1 to 4094.
Usage guidelines
You can configure multiple actions of mirroring traffic to interfaces for a traffic behavior.
