The page includes the following fields:
Object Description
Port List Select a port number from this drop-down menu.
Port Type Displays protected port types.
Protected : A single stand-alone VLAN that contains one
promiscuous port and one or more isolated (or host) ports. This VLAN
conveys traffic between the isolated ports and a lone promiscuous
port.
Unprotected : A promiscuous port can communicate with all the
interfaces within a private VLAN. This is the default setting.

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.
