ExtremeXOS 12.5.4 Release Notes
12
● Extreme Network Virtualization (XNV)—The Extreme Network Virtualization (XNV) feature, which
is also known as Virtual Machine (VM) tracking, supports VM port movement, port configuration
for VMs, and VM inventory on network switches. The XNV feature enables a switch to configure
switch ports in response to VM detection and port movement and report VM activity to network
management software.
● FDB Entry Statistics—The show fdb stats command has been updated to display information that
is dynamically updated. A
no-refresh option is provided for those who prefer the static display.
● Identity Management, Phase 2—The identity management feature has been extended to support
identity authentication through a RADIUS server or local database. As part of the authentication,
identities can be associated with hierarchical roles, to which policies or dynamic ACL rules are
attached. These policies and rules can be used to configure port settings for the discovered identity.
● IP ARP Entry Statistics—The show iparp stats command has been added to display IP ARP
statistics in a display that is dynamically updated. Statistics can be displayed for VRs, ports, or
VLANs.
● IPFIX Protocol Support—The IP Flow Information Export (IPFIX) protocol captures information
about traffic flows passing through network elements in a data network and sends the information
to an external collector.
● IP Multicast Scaling Enhancement—To support more IP multicast (IPMC) FDB entries,
BlackDiamond 8900 series modules with external tables can now be configured to support additional
IPMC FDB entries. This feature is configured with the
configure forwarding external-tables
command.
● LAG Port Selection—This feature allows you to apply an ACL that causes matching packets to
egress a specific port in a link aggregation (or load-sharing) group.
● Login Banner Enhancements—A user configurable banner can now be displayed after a successful
login. Enhancements for banners used with network login have also been added.
● MIB Support for Extreme Target Address MIB—Support for the VR option has been added to the
Extreme target-addr MIB.
● Mirroring Scaling—On all ExtremeXOS platforms, the maximum number of mirroring filters has
been increased from 16 to 128. The maximum number of VLAN or virtual ports filters remains at 16.
If there are no configured VLAN or virtual port filters, 128 ports can be mirrored. If you have the
maximum of 16 VLAN or virtual ports filters configured, 112 ports (128-16) can be configured.
● MLAG Switch Support—The multi-switch link aggregation group (MLAG) feature allows you to
combine ports on two switches to form a single logical connection to another network device. The
other network device can be either a server or a switch and is separately configured with a regular
LAG (or appropriate server port teaming) to form the port aggregation. The basic operation of this
feature requires two ExtremeXOS switches interconnected by an inter-switch connection (ISC).
● MPLS Support on BlackDiamond 8800 Series Switches—Multiprotocol Label Switching (MPLS) is
now supported on BlackDiamond 8800 series switches that contain only certain BlackDiamond 8900
series modules: 8900-10G8X-xl, 8900-G48T-xl, 8900-G48X-xl with MSM 8900-MSM128. Be sure to read
the ExtremeXOS Concepts Guide, as this feature is only supported when the proper hardware,
software, and feature pack is installed.
● MPLS Support on Summit X460 and X480 Switches—MPLS is now also supported on Summit X460
and X480 switches. Be sure to read the ExtremeXOS Concepts Guide, as this feature is only supported
when the proper hardware, software, and feature pack is installed.
● Packet Buffer Configuration—This feature provides more efficient buffer usage and more control of
buffer usage on select BlackDiamond 8000 series modules and Summit family switches. Control is
implemented through the
configure port shared-packet-buffer command.
● Power over Ethernet plus (PoE+)—PoE+ (IEEE 802.3at) has been implemented and supports up to
30W at the power sourcing equipment.
