• You cannot configure LPS on link aggregate ports.
Learned MAC Address Notification
The LPS feature enables the OmniSwitch to generate an SNMP trap when a new bridged MAC address
is learned on an LPS port. A configurable trap threshold number is provided to determine how many
MAC addresses are learned before such traps are generated for each MAC address learned thereafter.
Trap contents includes identifying information about the MAC, such as the address itself, the
corresponding IP address, switch identification, and the slot and port number on which the MAC was
learned.
Link Aggregation (static & 802.3ad)
Alcatel-Lucent’s link aggregation software allows you to combine several physical links into one large
virtual link known as a link aggregation group. Using link aggregation can provide the following
benefits:
• Scalability (OS6400/6850/6855). You can configure up to 32 link aggregation groups that can
consist of 2, 4, or 8 Ethernetports.
• Scalability (OS9000/OS9000E). You can configure up to 128 link aggregation groups that
can consist of 2, 4, or 8 Ethernetports.
• Reliability. If one of the physical links in a link aggregate group goes down, the link
aggregate group can still operate.
• Ease of Migration. Link aggregation can ease the transition from a Gigabit Ethernet backbone
to a 10 Gigabit Ethernet backbone.
• Interoperability with Legacy Switches. Static link aggregation can interoperate with
OmniChannel on legacy switches.
Alcatel-Lucent’s link aggregation software allows you to configure the following two different types of
link aggregation groups:
• Static link aggregate groups
• Dynamic (802.3ad) link aggregate groups

Multiple Virtual Routing and Forwarding (Multiple-VRF)
The Multiple Virtual Routing and Forwarding (VRF) feature provides the ability to configure
separate routing instances on the same switch. Similar to using VLANs to segment Layer 2 traffic,
VRF instances are used to segment Layer 3 traffic.
Some of the benefits of using the Multiple VRF feature include the following:
