Appendix C: Port Based VLAN Setup
VLAN support on the E7 is divided into two types:
•
On the Ethernet interfaces G1, G2 and G3, VLANs are created by configuring them normally
in cOS Core. It is cOS Core that then takes on the task of adding and recognizing VLAN tags in
packets. It is not a hardware function.
Setting this up is discussed in the separate
cOS Core Administration Guide
.
•
For the GESW interfaces only (numbered 1 to 8), VLANs are configured in cOS Core in a way
that is unique to the E7.
All 8 GESW interfaces are connected together by a common hardware switch fabric and this
fabric also takes care of managing the packet tagging for any VLANs configured on the
interfaces. This is referred to as
Port Based VLANs
.
This section describes VLAN configuration for the GESW interfaces.
The arrangement of VLANs on the GESW interfaces can be done in a number of ways:
•
Each of the 8 GESW interfaces has the possibility of being a separate VLAN or part of a VLAN
group.
The GESW interfaces that are not part of a VLAN will continue to operate as a single interface
with the logical name GESW in cOS Core since they are connected via a common switch
fabric.
•
For example, the 8 GESW interfaces could be divided so that the first 2 GESW interfaces
could be on one VLAN, the next 3 interfaces could be on a second VLAN and the last 3 could
be left in normal operation.
There is no need to make the final 3 interfaces part of a VLAN since there are already joined as
the interface GESW through the switch fabric.
Configuring VLANs
How to configure port based VLANs will be illustrated with an example. Assume that the
requirement is to divide the GESW interfaces as follows:
•
The first interface will continue to operate normally through the switch fabric. This will
therefore be the logical cOS Core interface GESW.
•
The GESW interfaces 2, 3 and 4 will become three separate VLANs with the logical names
gesw_port2, gesw_port3 and gesw_port4.
•
The four GESW interfaces 5, 6, 7 and 8 will become a single VLAN with the logical name
gesw_port5-8.
To configure these VLANs, perform the following steps in the Web Interface:
1. Define the VLAN objects
In the Web Interface, go to Network > Interfaces and VPN > VLAN > Add and add four new
VLAN
objects. Each should have an arbitary value assigned for the
VLAN ID
,
IP Address
and
Network
properties. The
VLAN ID
need only be unique for the GESW interface. The IP addresses
should not be public IPv4 addresses.
