Quick Steps for Configuring Port Mirroring
1 Create a port mirroring session. Be sure to specify the port mirroring session ID, source (mirrored) and
destination (mirroring) slot/ports, and unblocked VLAN ID (optional—protects the mirroring session
from changes in Spanning Tree if the mirroring port monitors mirrored traffic on an RMON probe
belonging to a different VLAN). For example:
-> port-mirroring 6 source 2/3-9 destination 2/10 unblocked-vlan 7
