Note: This function is not supported on N-Series Gold, X-Series, stackable or standalone fixed
switch devices.
Note: When creating a static LAG for port mirroring, you must assign a unique admin key to
aggregating ports. If ports other than the desired underlying physical ports share the same admin
key value, aggregation will fail or undesired aggregations will form.
Procedure 1 Configuring a Static LAG for an IDS Mirror
Step Task Command(s)
1. Create a static LAG aggregating ports ge.1.1
through ge.1.5 into LAG port 21 and assign a
unique admin key to that LAG port.
set lacp static lag.0.21 key 4000
ge.1.1-5
2. Create a port mirror between source port
ge.1.10 and the static LAG.
set port mirror create fe.1.10
lag.0.21 both
