Packet Filter Type

Choose Any or IP or PPPoE from the drop-down list. Choose Any to allow all kinds of

 

 

 

packets, IP to allow IP packets only or PPPoE to allow PPPoE packets only.

Click Apply to save your changes back to the IES-1000's volatile memory. The IES-1000

 

 

 

loses these changes if it is turned off or loses power, so use the Config Save link on the

 

 

 

navigation panel to the left to save your changes to the non-volatile memory when you

 

 

 

are done configuring.

10.5Port Filter (Port-based VLAN)

The IES-1000 port filter (or port-based VLAN) mechanism can be used to limit the broadcast domain to the members of a port filter group only. In this way, the port filter increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast frames go to each and every individual port.

The stations on a logical network belong to one group; however, a station can belong to more than one group. Subscribers of one group are not allowed to access the resources of other groups and a higher level of security is achieved. This isolates the subscribers from one another and prevents a subscriber from discovering the resources, for example, shared drives or printers, of another subscriber.

In the IES-1000 port filter, the allowable outgoing port(s) of each incoming port must be defined. Ethernet frames are forwarded according to these rules. Therefore, if you wish to allow two subscriber ports to talk to each other, for example, between conference rooms in a hotel, you must define the egress port (outgoing port) for both ports. An egress port is an outgoing port, that is, a port through which a data frame leaves. Port filters are specific only to the switch on which they were created.

The factory default settings for the port-based filter of the IES-1000 are:

-Bridge port 1 (Ethernet port) allowed to all bridge ports

-Bridge port 2 (DSL port 1) allowed to bridge port 1 (Ethernet port) only

-Bridge port 3 (DSL port 2) allowed to bridge port 1 (Ethernet port) only

-Bridge port 4 (DSL port 3) allowed to bridge port 1 (Ethernet port) only

-Bridge port 5 (DSL port 4) allowed to bridge port 1 (Ethernet port) only

-Bridge port 6 (DSL port 5) allowed to bridge port 1 (Ethernet port) only

-Bridge port 7 (DSL port 6) allowed to bridge port 1 (Ethernet port) only

-Bridge port 8 (DSL port 7) allowed to bridge port 1 (Ethernet port) only

-Bridge port 9 (DSL port 8) allowed to bridge port 1 (Ethernet port) only

The default port filter settings allow each DSL port to communicate back and forth with only the Ethernet port, and not with other DSL ports. The following figure illustrates this.
