Description
Port to mirror on
Port to mirror is also known as the mirror port. Frames from ports that
have either source (rx) or destination (tx) mirroring enabled are
mirrored on this port.
Disabled
disables mirroring.
Port
The logical port for the settings contained in the same row,
*
indicates that all ports are selected.
Mode
Select mirror mode.
Note:
For a given port, a frame is only transmitted once. It is therefore not possible to
mirror Tx frames on the mirror port. Because of this, the mode for the selected mirror
port is limited to
Disabled
or
Rx only
.

Link aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a
single Link Aggregated Group (LAG). Port aggregation multiplies the bandwidth
between the devices, increases port flexibility, and provides link redundancy.
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports
in a LAG can be of different media types (UTP/Fiber, or different fiber types), provided
they operate at the same speed.
Aggregated links can be assigned manually (Port Trunk) or automatically by enabling
Link Aggregation Control Protocol (LACP) on the relevant links.
Aggregated links are treated by the system as a single logical port. Specifically, the
aggregated link has similar port attributes to a non-aggregated port, including auto-
negotiation, speed, duplex setting, etc.
The industrial managed switch supports the following aggregation links :
• Static LAGs (Port Trunk)
–
Force aggregated selected ports to be a trunk group.
• Link Aggregation Control Protocol (LACP) LAGs – LACP LAGs negotiate
aggregated port links with other LACP ports located on a different device. If the
other device ports are also LACP ports, the devices establish a LAG between them.
