Overview
ExtremeXOS 12.5.4 Release Notes
13
● Priority Flow Control—This feature provides the functionality to allow traffic associated with certain
priorities to be paused while traffic associated with other priorities on the same port continues to
flow.
● Round Robin LAG—The round robin algorithm is used to select a member from a LAG to route a
packet rather than using a hash algorithm that is based on the L2/l3 address fields of the packet.
● “show tech” Command Enhancements—The commands show management and ls internal-
memory
have been added to the output of the show tech command.
● SummitStack-V—This feature uses 10 Gb or faster switch ports as stacking ports, which allows
greater cable distances between stacking nodes and allows a stack to span between racks, building
floors, or buildings.
● SyncE—Synchronous Ethernet (SyncE) allows the hardware to synchronize the clock time that is
used for data transmission to a reference clock. The primary reference clock comes from a base
station controller.
● Tunable DWDM—Tunable Dense Wavelength Division Multiplexing (DWDM) allows you to
configure a DWDM channel to a DWDM capable XFP module on a port, providing the capability to
multiplex 40x10G traffic over a single fiber. Supported on Summit X480 series switches,
BlackDiamond 20800 series switches, and BlackDiamond 8800 series switches.
● Virtual Router Scaling—The software now supports Virtual Router and Forwarding instances
(VRFs), which are an extension of the VR feature. VRFs function as children of VRs and support
many more VR instances than previously provided by the VR feature.
● VLAN Statistics Support for BlackDiamond 8800 Series Switches and Summit Family Switches—
Support for VLAN statistics is based on the current implementation of VLAN statistics on the
BlackDiamond 12800 series switch. Statistics gathering is initiated through the configure ports
[<port_list>| all] monitor vlan <vlan_name> CLI command. Packet and byte counters are displayed on
a per-port per-VLAN basis using the show ports {<port_list>} vlan statistics {no-refresh} CLI command
or through SNMP Gets.
● VPLS MIB Enhancement for EPICenter—ExtremeXOS 12.5.1 introduces new VPLS MIBs for
EPICenter.
● Virtual Router Support for OSPFv3 and RIPng—IPv6 unicast routing protocols (OSPFv3 and
RIPng) are now supported in user created virtual routers (VRs).
● Wide Key ACL—This feature allows the use of a 362-bit double wide match key instead of a
standard 181-bit single wide key to be used with match conditions. It allows you to add more match
conditions to an ACL and also allows matching on a full destination-source IPv6 address.
