effect on ports that have Packet Type set to "Tagged Only." (Default PVID: 1) It is
not possible to remove a port from VLAN 1 unless its PVID has been changed to
something other than 1. Outgoing packets are tagged unless the packet's VLAN ID
is the same as the PVID. When the PVID is set to "None," all outgoing packets are
tagged.
※Note: If you select "Tagged Only" mode for a port, we recommend setting the
PVID to "None" as the standard configuration.
Aggregation
Port trunk allows multiple links to be bundled together and act as a single physical
link for increased throughput. It provides load balancing, and redundancy of links in a
switched inter-network. Actually, the link does not have an inherent total bandwidth
equal to the sum of its component physical links. Traffic in a trunk is distributed
across an individual link within the trunk in a deterministic method that called a hash
algorithm. The hash algorithm automatically applies load balancing to the ports in
the trunk. A port failure within the trunk group causes the network traffic to be
directed to the remaining ports. Load balancing is maintained whenever a link in a
trunk is lost or returned to service.
Aggregation / Trunking Configuration
To assign a port to a trunk, click the required trunk number, and then click Apply.
LACP
IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by
automatically aggregating several physical links together as a logical trunk and
providing load balancing and fault tolerance for uplink connections.
