The following sections detail what is new in this document.
7520 Series adds support for a new model, 7520-48YE-8CE. 7520-48YE-8CE provides the following ports:
In addition to the fixed ports, the switch provides one RJ-45 interface port, one Type A USB port, dual redundant hot-swappable power supplies, and six hot-swappable fan units.
Software feature support on the new model matches feature support of 7520-48Y-8C and also includes MACsec.
Feature content is updated to include this new model. For high-level feature support information, see Fabric Engine and VOSS Feature Support Matrix.
This document includes a new flowchart to illustrate the logic of Auto-sense FA Proxy Ring. For more information, see Auto-sense FA Ring Proxy Switch.
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 DHCP Server.
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 Configure Endpoint Tracking Interfaces
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 the following sections:
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+.
For more information, see the following sections:
Configure Boot Flags (EDM)
This release introduces the following enhancements:
5320 Series licensing—5320 Series switches no longer require a license to operate SFP+ ports at full 10 Gbps.
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.
For more information, see Fabric Engine CLI Commands Reference.
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.
For more information, see System Access.
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.
For more information, see Reset the Platform.
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.
For more information, see Disable a CLI User.
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.
For more information, see Extreme-Dynamic-Client-Assignments.
You can now configure Open Shortest Path First Version 3 (OSPFv3) instances to use circuitless IP (CLIP) interfaces. Support includes either the Global Router or for specific Virtual Router Forwarding (VRF) instances.
For more information, see OSPFv3 Support for CLIP Interfaces.
Use this feature to source Fabric Extend tunnels from a second FE tunnel source IP and second underlay VRF. You can create parallel Fabric Extend IP tunnels between two nodes for redundancy.
For more information, see Parallel Tunnel Support for Fabric Extend.
In this release, the following enhancements are made for SD-WAN:
For more information, see Auto-sense Port States.
This release introduces the following ZTP + configuration enhancements for ExtremeCloud IQ ‑ Site Engine:
Management I-SID on-boarding
CLIP configuration
For more information, see ZTP+ Phases of Operation.
The following commands are deprecated in this release, and related content is removed:
Use the trace level and show trace level commands instead.
For more information, see Use Trace to Examine IS-IS Control Packets.
The CLI procedure Enabling routing on an IP interface is removed from the document because it referenced an obsolete command. The command routing enable in GigabitEthernet Interface Configuration and VLAN Interface Configuration mode is obsolete in all syntax variations, including no and default.
