The following table describes the labels in this screen.
Table 12 Port Isolation
LABEL DESCRIPTION
Port Select a port number to configure its port isolation settings.
Select All Ports to configure the port isolation settings for all ports on the
Switch.
Egress Port An egress port is an outgoing port, that is, a port through which a data
packet leaves.
Selecting a port as an outgoing port means it will communicate with the
port currently being configured. If you wish to allow two subscriber ports to
talk to each other, you must define the egress port for both ports.
CPU refers to the Switch management port. By default it forms a VLAN
with all Ethernet ports. If it does not form a VLAN with a particular port
then the Switch cannot be managed from that port.
Select All/
Deselect All Click Select All to mark all ports as egress ports and permit traffic.
Click Deselect All to unmark all ports and isolate them.
Deselecting all ports means the port being configured cannot communicate
with any other port. This will also deselect the CPU outgoing port which will
disable Switch management for that port. This option is the most limiting
but also the most secure.
Apply Click this to save any changes to the Switch.
Refresh Click this to reload the screen and reset any changes that were just made.
