● Revised QoS Meters Description—For ExtremeXOS 12.5.2 and later, the description of QoS meters is
changed as follows:
On BlackDiamond
®
8800 series switches, SummitStack™, and Summit
®
family switches that are
supported by this software release, meters are a per-VLAN resource. For example, if you assign a 50
Mbps meter to a VLAN, the total throughput for all ports in that VLAN is limited to 50 Mbps.
(PD4-1727668151)
● Secure Shell (SSH) Serialized Licensing and Distribution—Extreme Networks has enhanced its processes
regarding SSH licensing. SSH contains strong encryption algorithms, which heightens the export
controls required in the United States and other countries. SSH is now delivered and licensed on a
serialized basis, with a separate license key required to activate SSH on each Extreme Networks
switch. See the ExtremeXOS Concepts Guide, Software Version 12.5.2, for more detailed information.
For frequently asked questions (FAQs) pertaining to the SSH License Process Change, see Product
Change Notice No. 2011002, “ExtremeXOS SSH Process Change” on eSupport.
