DESCRIPTION
The text box displays how long (in seconds) an SNMP request times out. You may
change the timeout by typing a new number in the text box and then clicking the Apply
button.
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.
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.
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.
