Example 5, Filtering Traffic According To A Classification; Example 5, Filtering Traffic According To A Layer 4 Classification Rule - Enterasys SmartSwitch 2200 Management Supplement

Any AppleTalk frame received on ports 2 through 8 will be broadcast to all other ports on Switch
5 associated with the AppleTalk protocol. For example, if Port 2 received a frame with the
AppleTalk protocol, Switch 5 would only transmit the frame to Ports 2, 3, 4, 6, 7, and 8.
6. Use the VLAN Forwarding Configuration screen to assign Port 1 to the Yellow VLAN and set
the frame type to tagged. With this configuration, the frames transmitted on Port 1 are tagged as
being from the Yellow VLAN.
If a frame associated with any protocol other than AppleTalk (for example, for the mail server)
is received on any of the Ports 2 through 8, the frame would be part of the Yellow VLAN and
transmitted out Port 1 as a tagged frame to Switch 3. The frame would be handled in the same
manner as described in the previous examples to route the frame to the Mail Server on the first
floor.
Any unicast frames received via Port 1 that are destined for a device in the Yellow VLAN are
transmitted to the correct device. Any broadcast frames received via Port 1 are transmitted to all
the devices in the Yellow VLAN and handled in a similar manner as previously described in
Example 2.
3.2 EXAMPLE 5, FILTERING TRAFFIC ACCORDING TO A LAYER 4
CLASSIFICATION RULE
This example illustrates how to filter out broadcast transmissions at Layer 4 from other parts of a
network.
In this example, illustrated in
operating. However, it was discovered that the Routing Information Protocol (RIP) broadcast
frames from routers R1 and R2 were flooding the subnetwork of Switches S1 and S2.
