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.

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.
