36.2 Protected Port
36.2.1 Overview
Under certain application contexts, it is required that some ports on the same device should
not communicate mutually. In such cases, communication, including unicast frames,
broadcast frames and multicast frames, among these ports is not forwarded between the
protected ports. To achieve this purpose, you can set some ports as protected ports.
After these ports are set as the protected ports, they cannot communicate with each other;
but protected ports can still communicate with unprotected ports.
Protected ports provide two modes: denying layer 2 forwarding between protected ports but
allowing layer 3 routing between protected ports; denying layer 2 forwarding and layer 3
routing between protected ports. If both modes are supported, the first one is
defaulted.When you set two protected ports as a SPAN port pair, the frames transmitted or
received by the source port of SPAN are sent to the destination port of SPAN according to
the SPAN setting. Therefore, it is not recommended to set the destination port of SPAN as
the protected port (and you can also save system resources).
The device supports the Aggregated Port as the protection port. When you set an
Aggregated Port as the protection port, all the member ports of the Aggregated Port will be
set as the protection port.
