The following is an example of the display you see when you display load sharing, or link aggregation,
on the Aspen 8810 switch:
Load Sharing Monitor

Link Status: (A) Active, (D) Disabled, (R) Ready
Load Sharing Algorithm: (L2) Layer 2 address based, (L3) Layer 3 address based

Number of load sharing trunks: 1
Refer to “Displaying Port Configuration Information” for information on displaying summary load-
sharing information.
Switch Port Mirroring
Port mirroring configures the switch to copy all traffic associated with one or more ports. The monitor
port can then be connected to a network analyzer or RMON probe for packet analysis. The system uses
a traffic filter that copies a group of traffic to the monitor port. You can have only one monitor port on
the switch.
Up to 16 mirroring filters and 1 monitor port can be configured. After a port has been specified as a
monitor port, it cannot be used for
any other function.
Switch port mirroring is disabled by default.
NOTE
Frames that contain errors are not mirrored.
Switch Port Mirroring on the Aspen 8810 Switch Only
The traffic filter for port mirroring on the Aspen 8810 switch is defined based on the physical port.
Additionally, you configure whether to mirror only ingressing traffic, only egressing traffic, or both. The
default setting is to mirror all forwarded traffic. (You do not need to explicitly configure the monitor
port as tagged or untagged on the Aspen 8810 switch.)
You cannot include the monitor port in a load-sharing group.
