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/

Click Select All to mark all ports as egress ports and permit traffic.

Deselect All

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.
