Configuring Local Port Mirroring
– 137 –
Configuring Local Port Mirroring
Use the Interface > Port > Mirror page to mirror traffic from any source port to a
target port for real-time analysis. You can then attach a logic analyzer or RMON
probe to the target port and study the traffic crossing the source port in a
completely unobtrusive manner.
Figure 59: Configuring Local Port Mirroring
Command Usage
◆ Traffic can be mirrored from one or more source ports to a destination port on
the same switch (local port mirroring as described in this section), or from one
or more source ports on remote switches to a destination port on this switch
(remote port mirroring as described in “Configuring Remote Port Mirroring” on
page 139).
◆ Monitor port speed should match or exceed source port speed, otherwise
traffic may be dropped from the monitor port.
◆ When traffic matches the rules for both port mirroring, and for mirroring of
VLAN traffic or packets based on a MAC address, the matching packets will be
sent to one of them based on configuration order.
◆ The destination port cannot be a trunk or trunk member port.
◆ Note that Spanning Tree BPDU packets are not mirrored to the target port.
Parameters
These parameters are displayed:
◆ Source Port – The port whose traffic will be monitored.
◆ Target Port – The port that will mirror the traffic on the source port.
◆ Type – Allows you to select which traffic to mirror to the target port, Rx
(receive), Tx (transmit), or Both. (Default: Both)
Web Interface
