DESCRIPTION

Timeout

The text box displays how long (in seconds) an SNMP request times out. You may

(seconds)

change the timeout by typing a new number in the text box and then clicking the

 

Apply button.

 

 

Setting Wizard

Choose from All connected or Port isolation.

 

All connected means all ports can communicate with each other, that is, there are no

 

virtual LANs. All incoming and outgoing ports are selected. This option is the most

 

flexible but also the least secure.

 

Port isolation means that each port can only communicate with the CPU

 

management port and cannot communicate with each other. All incoming ports are

 

selected while only the CPU outgoing port is selected. This option is the most limiting

 

but also the most secure.

 

After you make your selection, click Apply to display the screens as mentioned

 

above. You can still customize these settings by adding/deleting incoming or outgoing

 

ports, but you must also click Apply at the bottom of the screen.

 

 

Incoming

These are the ingress ports; an ingress port is an incoming port, that is, a port through

 

which a data packet enters. If you wish to allow two subscriber ports to talk to each

 

other, you must define the ingress port for both ports. The numbers in the top row

 

denote the incoming port for the corresponding port listed on the left (its outgoing

 

port). 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.

 

 

Outgoing

These are the egress ports; an egress port is an outgoing port, that is, a port through

 

which a data packet leaves. 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.
