The following sections describe what is new in this release:
DHCP Server simplifies your deployment, saving you time and money by removing the need to deploy an external DHCP server. With this feature, the switch hosts the DHCP server. DHCP Server is supported for IPv4 networks only. With IPv6, you must deploy an external DHCP server.
For more information, see VOSS User Guide.
This release removes the consistency check on isolated and promiscuous ports for both regular and MLT Flex-UNI ports on Endpoint Tracking interfaces. To support E-Tree Private VLAN with Endpoint Tracking, you must create a Private VLAN with I-SID and configure access ports as PVLAN isolated or promiscuous.
For more information, see VOSS User Guide.
This release supports Fabric Attach interfaces that connect to ISW-Series Managed Industrial Ethernet Switches (ISW) with a ring topology.
You can enable Fabric Attach (FA) Ring Topology Change Notification (TCN) processing on an FA interface that connects to an ISW-Series switch either manually or dynamically through Auto-sense.
For more information, see VOSS User Guide.
The following table identifies the ISW-Series Managed Industrial Ethernet Switches that initially support this feature, and the minimum software version required.
|
Model |
Minimum version |
|---|---|
|
ISW 168xx |
v01.01.05.0001 |
|
ISW-4W-4WS-4X |
v00.00.01.0003 |
For ISW-Series Managed Industrial Ethernet Switches documentation, see https://supportdocs.extremenetworks.com/support/documentation/industrial-switches/.
The boot config flags factorydefaults zero-touch-config-only command boots the switch with a default configuration that does not reset secure files, keeps the security mode, enables Auto-sense, and performs ZTP+.

This release introduces the following enhancements:
Additional resource information—The show io l2-tables command output includes multicast information. The show io l3-tables command supports a multipath parameter to see multipath egress objects, like how many ECMP resources are in use.
IPv4 static routes—You can use Classless Inter-Domain Routing (CIDR) notation with the ip route command to configure a static route in the GRT or a VRF. Example: ip route 192.1.1.0/24.
Password updates—You can now use passwords of up to 80 characters in length for all CLI passwords. The password cannot contain the username in either forward or reverse order.
Reboot timer—The reset -in WORD<1-7> command restarts the switch after the configured timer expires. With the delayed reset functionality, you can make running configuration changes on the switch without affecting the saved configuration. If those changes cause a configuration issue, the automatic restart reverts the switch to the saved configuration. You can also use this option to upgrade the software but delay the switch restart until a planned maintenance window.
User account management—The no username <name> enable command has been extended to support l1, l2, l3 access level users. In previous releases, you were required to use the password access-level command to disable the l1, l2, l3 access level users.
Web server management—You can use the no web-server ssl-renegotiation command to disable SSL renegotiation in the web server.

This release extends the Extreme-Dynamic-Client-Assignments Vendor
Specific Attribute (VSA) to include the mvni=ISID option to configure IP Multicast config-lite for Fabric Connect through RADIUS. In an earlier release,
you could configure IP Multicast config-lite for Fabric Connect using CLI and EDM only.
