Chapter 7: Configuring VLANs on the SSR
• When removing ports from a VLAN, you can remove all of a module’s ports at one
time rather than removing them individually.To do so, click rather than double-clock
the module in the Selected Port List box of the dialog box you use to add ports. Then
click the Remove button.
Defining Access Ports and Trunk Ports
You can define ports as either access or trunk ports.
All ports are configured as access ports by default. Therefore, you need to define a port as
an access port only if you previously defined it as a trunk port and now want to use it as
an access port, instead. Access ports can be added to only one VLAN.
Define a port as a trunk port if you want to include that port in multiple VLANs. Trunk
ports are useful for connecting SSRs together and for sending traffic of multiple VLANs
on a single network segment connecting the routers. Suppose you have two
VLANs/subnetworks of IP users on separate SSRs and those VLANs need to belong to
the same layer broadcast domain. You could trunk two SSRs together as shown in the
following figure:
To define access ports and trunk ports:
1. Start Configuration Expert if you have not already done so.
Note: If you start Configuration Expert from the Schematic view choosing the
Configure VLAN command, Configuration Expert automatically expands
the Active Configuration file’s tree to the VLAN Configuration object. If you
are adding a VLAN to the Active Configuration file, go to
step 3 .
2. Open the configuration file you want to modify and then double-click that file’s
Bridging Configuration object.
3. Click the Port Bridging Mode object.
A Bridging VLAN Mode dialog box similar to the following appears:
SSR1 SSR2
VLAN1 VLAN1
VLAN2 VLAN2
Trunk
