Local and Remote Port Mirroring
The following constraints and limitations apply to local and remote port mirroring with
the QFX Series:
• You can create a total of four port-mirroring configurations on a QFX Series standalone
switch.
• You can create a total of four port-mirroring configurations on each Node group in a
QFabric system, subject to the following constraints:
• As many as four of the configurations can be for local port mirroring.
• As many as three of the configurations can be for remote port mirroring.
• Regardless of whether you are configuring a standalone switch or a Node group, the
following limits apply:
• There can be no more than two configurations that mirror ingress traffic. (If you
configure a firewall filter to send traffic to a port mirror—that is, you use the analyzer
action modifier in a filter term—this counts as an ingress mirroring configuration for
switch or Node group on which the filter is applied.)
• There can be no more than two configurations that mirror egress traffic.
