To define a load-sharing group, you assign a group of ports to a single, logical port
number. To enable or disable a load-sharing group, use the following commands:
enable sharing <port> grouping <portlist> {port-based | address-based |
round-robin}
disable sharing <port>

XAMPLE
The following example defines a load-sharing group that contains ports 9 through 12,
and uses the first port in the group as the master logical port 9:
enable sharing 9 grouping 9-12
In this example, logical port 9 represents physical ports 9 through 12.
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.
Do not disable a port that is part of a load-sharing group. Disabling the port
prevents it from forwarding traffic, but still allows the link to initialize. As a result,
a partner switch does not receive a valid indication that the port is not in a
forwarding state, and the partner switch will continue to forward packets.

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.
