instance with a specific Forwarding Engine Board (FEB). You cannot associate a
port-mirroring instance with an FEB configured as a backup FEB. On the M320 router,
you can associate each instance with a specific Flexible PIC Concentrator (FPC).
Associating a port-mirroring instance with an FPC or an FEB enables you to mirror packets
to different destinations. Multiple port-mirroring instances are also supported on MX
Series routers. For information about configuring multiple port-mirroring instances on
MX Series routers, see the Junos Layer 2 Configuration Guide.
To configure a port-mirroring instance, include the instance port-mirroring-instance
statement at the [edit forwarding-options port-mirroring] hierarchy level:
[edit forwarding-options port-mirroring]
instance port-mirroring-instance-name {
family (inet | inet6 | vpls | ccc) {
output {
interface interface-name {
next-hop address;
}
no-filter-check;
}
}
input {
maximum-packet-length bytes;
rate number;
run-length number;
}
}
Configuring Port-Mirroring Instances
You can configure multiple port-mirroring instances. Specify a unique
port-mirroring-instance-name for each instance you configure.
Associating a Port-Mirroring Instance on M320 Routers
You can associate a port-mirroring instance with a specific FPC on an M320 router or
with a specific FEB on an M120 router. You can associate only one port-mirroring instance
with each FPC on an M320 router or with each FEB on an M120 router. On an M120 router,
you cannot associate a port-mirroring instance with a FEB configured as a backup FEB.
To associate a port-mirroring instance with an FPC on an M320 router, include the
port-mirror-instance port-mirroring-instance-name statement at the [edit chassis fpc
slot-number] hierarchy level:
[edit chassis]
fpc slot-number {
port-mirror-instance port-mirroring-instance-name;
}
For slot-number, specify the slot number of the FPC you want to associate with the
port-mirroring instance. For port-mirroring-instance-name, specify the name of a
port-mirroring instance you configured at the [edit forwarding-options port-mirroring]
hierarchy level. For more information about configuring an FPC on an M320 router, see
the Junos System Basics Configuration Guide.
