Port Mirroring
The SecureStack B3 device allows you to mirror (or redirect) the traffic being switched on a port
for the purposes of network traffic analysis and connection assurance. When port mirroring is
enabled, one port becomes a monitor port for another port within the device.
Mirroring Features
The SecureStack B3 device supports the following mirroring features:
•
Mirroring can be configured in a many‐to‐one configuration so that one target (destination)
port can monitor traffic on up to 8 source ports. Only one mirror destination port can be
configured per stack, if applicable.
•
Both transmit and receive traffic will be mirrored.
•
A mirroring session which is configured to be active (enabled) will be operationally active
only if both a destination port and at least one source port have been configured.
•
A destination port will only act as a mirroring port when the session is operationally active. If
the mirroring session is not operationally active, then the destination port will act as a normal
port and participate in all normal operation with respect to transmitting traffic and
participating in protocols.
Select the ports for which to clear broadcast suppression thresholds. For a
detailed description of possible port‐string values, refer to "Port String
Syntax Used in the CLI" on page 5‐1.
Caution: Port mirroring configuration should be performed only by personnel who are
knowledgeable about the effects of port mirroring and its impact on network operation.
