New Features and Functionality in ExtremeXOS 12.5.1
This section lists the new features and functionality supported in ExtremeXOS 12.5.1 software:
● ACL Match Condition—Based on IEEE 802.1p, this feature provides the ability to create an access
list (ACL) based on VLAN tag priority information.
● Access Profile Logging—This feature provides ACL support for traffic reaching the following
applications: SNMP, Telnet, SSH2, and HTTP/HTTPS. This is in addition to using policy files to add
ACLs.
● Auto Provisioning for Edge Switches—This feature allows for the configuration of certain
parameters on a switch automatically using DHCP and TFTP servers. This process can make an
Extreme Networks switch ready to do the initial provisioning without any manual intervention.
● “check firmware version” CLI Command for the BlackDiamond 20800 Series Switch—Use the
new
check firmware version command to check whether any upgrade is to be done to any of the
uC or FPGAs. If an upgrade is required, the output shows the running and expected versions for the
boards. If there is no upgrade required, the same is printed. Refer to the ExtremeXOS Command
Reference Guide for more details.
● CLEAR-Flow Support—CLEAR-Flow is now supported on BlackDiamond 20800 series switches.
● Direct Attach—The direct attach feature is a port configuration feature that supports VM-to-VM
communication on a directly connected server that uses the Virtual Ethernet Port Aggregator (VEPA)
feature on that server. Without VEPA and direct attach, a VM server must use a virtual Ethernet
bridge or switch on the VM server to enable Ethernet communications between VMs. With VEPA
and direct attach, the VM server can rely on a directly connected switch to receive and reflect VM-to-
VM messages between VMs on the same server.
● Distributed IP ARP Mode for BlackDiamond 8800 Series Switches—This feature increases the IPv4
ARP limit from 16,000 up to a maximum of 260,000 on a BlackDiamond 8800 series switch. The
actual limit depends on the number and types of modules present on a BlackDiamond 8810 or
BlackDiamond 8806 switch.
● DDMI Optics—Digital Diagnostic Monitoring Interface (DDMI) optics provide critical information
about the installed Gigabit and 10 Gigabit optical transceiver modules.
● EAPS and PBB Redundant Access—EAPS now recognizes an SVLAN or CVLAN to BVLAN
mapping and makes the BVLAN facing port the Active-Open port, which keeps the link to the core
forwarding when the shared-port goes down.
● EAPS Priority Domains—EAPS now supports high and normal priority domains, allowing you to
give priority response to the most important protected VLANs if a ring fault occurs.
● EAPS Secondary Control Port—The EAPS hello packet period now supports more values
(
configure eaps hellotime), and the software supports transmission of hello PDUs out of the
secondary port (
configure eaps hello-pdu-egress). Secondary port hello PDU transmission is
provided for special circumstances; Extreme Networks recommends the default configuration,
primary port hello PDU transmission.
● Enable and Disable DHCP/BOOTP Relay per VLAN—Currently you can enable and disable
BOOTP relay only on a virtual router (VR), which means the DHCP is enabled or disabled on all
VLANs on that VR. With ExtremeXOS 12.5.1, you can enable or disable BOOTP relay a VR or on
individual VLANs.
● Enable and Disable SNMP per Virtual Router—To provide SNMP support based on a virtual
router, the existing enable/disable SNMP access CLI commands have been modified. These
commands now include a VR option. SNMP access is enabled by default on all VRs. If SNMP access
is disabled on a VR, the incoming SNMP request is dropped and an EMS log message is displayed.
