[edit forwarding-options]
user@switch# set next-hop-group nhg group-type layer-2
Specify the logical interfaces of the next-hop group:
3.
[edit forwarding-options next-hop-group next-hop-group-name]
user@switch# set interface logical-interface-name-1
user@switch# set interface logical-interface-name-2
For example, to specify ge-0/0/10.0 and ge-0/0/11.0 as the logical interfaces of the
next-hop group :

Juniper Networks devices allow you to configure port mirroring to send copies of packets
to either a local interface for local monitoring or to a VLAN or bridge domain for remote
monitoring. You can use mirroring to copy these packets:
Packets entering or exiting a port
Packets entering or exiting a VLAN or bridge domain
You can then analyze the mirrored traffic locally or remotely using a protocol analyzer
application. You can install analyzers on a system connected to the local destination
interface, or running on a remote monitoring station if you are sending mirrored traffic to
an analyzer VLAN or bridge domain.
This topic describes how to configure local mirroring on a switching device. The examples
in this topic describe how to configure a switching device to mirror traffic entering
