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 will monitor mirrored traffic on an RMON probe
belonging to a different VLAN). For example:
-> port mirroring 6 source 2/3 destination 2/4 unblocked 7
2 Enable the port mirroring session.
-> port mirroring 6 enable
Note. Optional. To verify the port mirroring configuration, enter show port mirroring status followed by
the port mirroring session ID number. The display is similar to the one shown below:
Session Mirrored Mirroring Mirror Mirroring Mirroring
slot/port slot/port Direction Vlan Status
----------+----------+----------+--------------+----------+----------
6. 2/3 6/4 bidirectional 7 ON
