a VLAN to operate in a MAC-based fashion. This means that each individual untagged supplicant,
identified by its MAC address, can be in different VLANs.

CLEAR-Flow
CLEAR-Flow is a broad framework for implementing security, monitoring, and anomaly detection in
ExtremeWare XOS software. Instead of simply looking at the source and destination of traffic, CLEAR-
Flow allows you to specify certain types of traffic that require more attention. Once certain criteria for
this traffic are met, the switch can either take an immediate, predetermined action; or it can send a copy
of the traffic to another device for analysis.
IPv6
With version 11.2, ExtremeWare XOS software supports IPv6. IPv6 is a more robust IP addressing
scheme and allows for next-generation routing.
NOTE
IP refers to IPv4; IPv6 is always referred to as IPv6.
For more information on IPv6, see Chapter 24 .
LLDP
ExtremeWare XOS version 11.2 introduces support for the Link Layer Discovery Protocol (LLDP). LLDP
is a Layer 2 protocol (IEEE standard 802.1ab) that is used to determine the capabilities of devices such
as repeaters, bridges, access points, routers, and wireless stations. ExtremeWare XOS version 11.2 LLDP
support enables devices to advertise their capabilities and media-specific configuration information and
to learn the same information from the devices connected to it.
LLDP provides a standard method of discovering and representing the physical network connections of
a given network management domain. LLDP works together with Extreme Discovery Protocol (EDP).
The LLDP neighbor discovery protocol allows you to discover and maintain accurate network
topologies in a multivendor environment.
For complete information on LLDP, see Chapter 6 .
LACP
Beginning with ExtremeWare XOS version 11.3, you can run the Link Aggregation Control Protocol
(LACP) on Extreme Networks devices. LACP enables dynamic load sharing and hot standby for link
aggregation links, in accordance with the IEEE 802.3ad standard. All third-party devices supporting
LACP run with Extreme Networks devices.
The addition of LACP provides the following enhancements to static load sharing, or link aggregation:
●
Automatic configuration
