C ONFIGURING P ORTS
When using load sharing, you should always reference the master logical port of
the load-sharing group (port 9 in the previous example) when configuring or
viewing VLANs. VLANs configured to use other ports in the load-sharing group
will have those ports deleted from the VLAN when load sharing becomes enabled.
V ERIFYING THE L OAD S HARING C ONFIGURATION
The screen output resulting from the show port config command indicates the ports
are involved in load sharing and the master logical port identity.

IRRORING
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:
• MAC source address/destination address — All data sent to or received from a
particular source or destination MAC address is copied to the monitor port.
• Physical port — All data that traverses the port, regardless of VLAN configuration,
is copied to the monitor port.
• VLAN — All data to and from a particular VLAN, regardless of the physical port
configuration, is copied to the monitor port.
• Virtual port — All data specific to a VLAN on a specific port is copied to the
monitor port.
Up to 8 mirroring filters and one monitor port can be configured on the switch. Once a
port is specified as a monitor port, it cannot be used for any other function.
Frames that contain errors are not mirrored.
