Port Mirroring Commands - D-Link xStack DGS-3612G series Cli Manual

xStack
The port mirroring commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
The primary purpose of the mirror function is to copy frames transmitted and received on a port and redirect the copies to another port.
The application attaches a monitoring device to the mirrored port, such as a sniffer or an RMON probe, to view details about the
packets passing through the first port. This is useful for network monitoring and troubleshooting purposes.

DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual
Note: When the device with the source port has been removed from a
stack, the configuration will be disabled temporarily until another device
has been installed in its place. If configurations are saved to NVR RAM
during this period the configuration will be removed forever.
Parameters
<port> {[add |delete] source ports <portlist> [rx|tx|both]}
Used to configure a mirror port − source port pair on the Switch.
Traffic from any source port to a target port can be mirrored for real-
time analysis. A logic analyzer or an RMON probe can then be
attached to study the traffic crossing the source port in a completely
obtrusive manner.
config mirror port <port> {[add |delete] source ports <portlist>
[rx|tx|both]}
This command allows a range of ports to have all of their traffic also
sent to a designated port, where a network sniffer or other device
can monitor the network traffic. In addition, users can specify that
only traffic received by or sent by one or both is mirrored to the
Target port.
<port> − This specifies the Target port (the port where mirrored
packets will be received). The target port must be operating at the
same speed as the source port. If the target port is operating at a
lower speed, the source port will be forced to drop its operating
speed to match that of the target port.
[add | delete] – Specify to add or delete ports to be mirrored that are
specified in the source ports parameter.
source ports – The port or ports being mirrored. This cannot include
the Target port.
• <portlist> − This specifies a port or range of ports that will
be mirrored. That is, the range of ports in which all traffic
will be copied and sent to the Target port. The beginning
and end of the port list range are separated by a dash.
