Commands for Configuring Slots and Ports on a Switch
configure mirroring add
configure mirroring add [vlan <name> {port <port>}| port <port> {vlan
<name>}]
Description
Adds a particular mirroring filter definition on the switch.
Syntax Description
Default
N/A.
Usage Guidelines
On a modular switch,
<port>
will be a slot and port in the form
<slot>:<port>
. For a detailed
explanation of port specification, see “Modular Switch Numerical Ranges” in Chapter 1.
You must enable port-mirroring using the
enable mirroring to port
command before you can
configure the mirroring filter definitions.
Up to 16 mirroring definitions can be added. You can mirror traffic from a VLAN, a physical port, or a
specific VLAN/port combination.
Port-mirroring configures the switch to copy all traffic associated with one or more ports to a monitor
port on the switch. The monitor port can be connected to a network analyzer or RMON probe for
packet analysis.The switch uses a traffic filter that copies a group of traffic to the monitor port. The
traffic filter can be defined based on one of the following criteria:
• Physical port —All data that traverses the port, regardless of VLAN configuration, is copied to the
monitor port.
• VLAN —All data to and from all members of a particular VLAN, regardless of the physical port
configuration, is copied to the monitor port. In the case of broadcast packets, this means that there
are multiple copies, one for each member port.
• Virtual port —All data specific to a VLAN on a specific port is copied to the monitor port.
Up to 16 mirroring filters and one monitor port can be configured on the switch. After a port has been
specified as a monitor port, it cannot be used for any other function. Frames that contain errors are not
mirrored.
