Flow Control
With flow control enabled on both the switch and its link partner and
full duplex mode enabled on the port, when congestion occurs the
port will send flow control frames to notify the link partner of such.
Upon receiving such frames, the link partner will temporarily stop
sending packets to the switch, thus avoiding packets drop and
ensuring a reliable network. Meanwhile, if a certain port receives
Pause frame it will also stop sending packets out.
By default, the flow control feature is disabled.
Note:

This switch does not support half-duplex flow control

Enabling full duplex mode can avoid data loss. However, this
will affect communication between source ports and other
devices. Thus, it is not advisable to use this feature on ports
which have Internet access.
Enable/Disable
Enable/Disable selected port(s). Once a certain port is disabled, the
port won
’t forward packets.
Isolation
Enable/Disable port isolation.
Only in 802.1Q VLAN mode, can this item be configured. By adding
ports into isolation groups, data isolation among ports in isolation
groups will be implemented.
Port isolation not only ensures better security, but provides users
with flexible networking solutions. By default, all ports are not
isolated.
Note:

Only when ports in the same isolation group cannot
intercommunicate, will intercommunication between ports
within an isolation group and ports outside this group not be
affected.

When a port in an aggregation group joins or leaves an
isolation group, other ports in this aggregation group will join or
leave the same isolation group automatically.

When a port in an aggregation group leaves an isolation group,
other ports in this aggregation group will remain in the same
isolation group, namely, isolation properties for ports in an
aggregation will not be affected.

When a non-isolated port joins an isolated aggregation group,
