ILC205 Function Module Installation and Operations Manual 7
Configuring the Module with InfinityLink Manager
Configuring the Module with InfinityLink Manager
You configure the ILC205 module operation using the InfinityLink Manager element management system and
the module’s configuration page.
Guidelines
You can configure the ILC205 Ethernet module to act as either a simple 802.3 switch or as a 802.3ac
VLAN-aware switch. This configuration setting applies to all ports. With VLAN support enabled, you can
enable double tagging (referred to as QinQ ) on a single trunking interface. Double tagging inserts a
second tag, known as the provider tag , that is formed from the Ether Type configured and the PVID
associated with the frames ingress port. This feature is intended to be used in conjunction with third-
party provider backbones that isolate each customer’s traffic based on unique tags. The inner tag is
copied from the original tagged frame and is called the Customer tag . Untagged traffic can not be
transported over a configured QinQ link, but can still pass between other ports on the module if needed.
Another key component of VLANs is the ability to prioritize traffic. This can be accomplished by attached
devices that send 802.1Q tagged frames with a tag and priority defined or by configuring the module to
add a default VLAN ID and priority on a port-by-port basis. The modules include four queues that are
mapped to the 802.1Q priorities (see Table 4 ). The module uses a strict priority scheduling algorithm that
forwards frames only when no higher priority frames are in the queue. Keeping the MGMT VLAN priority
at the highest priority (7) will help maintain your management connectivity over congested links.
Caution
Do not modify the VLAN configuration in such a way as to block your management traffic path.
Prerequisites
To configure the ILC205 module, you must access the InfinityLink Manager that manages the module. For
details about accessing and setting up InfinityLink Manager, see the
InfinityLink Manager Setup and Operations Manual .
