VLAN Port Configuration
Each column in the VLAN Port Configuration section of Figure 72 corresponds to a port.
Checkboxes in each column control which ports can transmit traffic that arrives on the
(column) port. For example, in the first column if only Port 2 is checked, then Port 1
(column 1) will only be allowed to send data out on Port 2 (checked box). Port 2 (second
column) is able to send data out on all other ports. All other ports, meanwhile, are only
allowed to send data out on Port 2. This configuration is also known as an Uplink
configuration for Port 2.
Each direction (for example, port 1 to port 2 versus port 2 to port 1) must be configured
separately. It is possible to configure a port to send data to a second port, but not allow
the second port to send data back to the first port (for example, check Port 8 in the Port 2
column, but do not check Port 2 in the Port 8 column). These settings should be changed
with caution, and with two-way communication in mind.
In all cases, even when not checked, all ports will still be able to communicate with the
CMMmicro management controller.
Setting (checking) any Uplink Port checkboxes (see Figure 72) will override VLAN Port
Configuration settings. If you desire complete control on a port-by-port basis using VLAN
Port Configuration, all Uplink Port boxes must be unchecked in the Uplink Port section.
