The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality.

Tenant Routed Multicast over BGP EVPN VXLANv6 |
Tenant Routed Multicast over BGP EVPN VXLANv6 enables the delivery of IPv4 and IPv6 multicast host traffic in BGP EVPN overlay multi-tenant fabric in an efficient and resilient manner. The new software capability enables IPv4 and IPv6 multicast in overlay with underlay network infrastructure natively running single-stack IPv6. The Tenant Routed Multicast over BGP EVPN VXLANv6 is supported over IPv6 Default MDT group. For more information, see Configuring Tenant Routed Multicast over BGP EVPN VXLANv6.

BGP EVPN VXLAN
|
The following BGP EVPN VXLAN features are introduced in this release:
|
Cisco StackWise Virtual |
Cisco StackWise Virtual is a network system virtualization technology that pairs two switches into one virtual switch to simplify operational efficiency with a single control and management plane. Starting with this release, the feature is supported on the C9500X-60L4D model of Cisco Catalyst 9500X Series Switches.
|
Custom EtherTypes |
Introduces support for configuring 0x9100 and 0x88a8 custom ethertypes. Use switchport dot1q ether type command in the interface configuration mode to configure this feature. This feature is supported only on Cisco Catalyst 9500X Series Switches.
|
Default Limits for redistributed routes and LSA in OSPF |
Default values have been assigned to the number of redistributed routes and LSAs in OSPF to prevent the device being flooded with routes. The default values for redistributed routes is 10240 routes. The default value for LSAs is 50,000 LSAs. You can customize the default values.
|
Deprecation of Weak Ciphers |
The minimum RSA key pair size must be 2048 bits. The compliance shield on the device must be disabled using the crypto engine compliance shield disable command to use the weak RSA key.
|
IPv6 support for SGACL |
Introduces support for IPv6 addressing of SGT and SGACL on the C9500X-28C8D. This allows dynamic learning of mappings between IP addresses and SGTs for IPv6 addresses.
|
LAN MACsec over MPLS |
Introduces support for MACsec with MPLS. This feature allows MPLS packets to be encrypted with a MACsec tag. This feature is not supported on Cisco Catalyst 9500X Series Switches.
|
MPLS VPN Inter-AS Option A |
Introduces support for MPLS VPN Inter-AS Option A on the C9500X-28C8D. Inter-AS Option A is the simplest to configure, and it provides back to back virtual routing and forwarding (VRF) connectivity.
|
NETCONF support for PTPv2 |
Introduces support for configuring PTPv2 with NETCONF. NETCONF provides a mechanism to install, manipulate, and delete the configuration of network devices.
|
Policy- Based Routing (PBR) |
Introduces support for policy-based routing on Cisco Catalyst 9500X Series Switches. You can use PBR to configure a defined policy for traffic flows.
|
Programmability
|
The following programmability features are introduced in this release:
|
Pseudowire Redundancy |
Introduces support for L2VPN pseudowire redundancy Cisco Catalyst 9500X Series Switches. This feature allows you to configure your network to detect a failure in the network and reroute the Layer 2 service to another endpoint that can continue to provide service.
|
show aaa dead-criteria radius enhancement command |
The show aaa dead-criteria radius enhancement command allows you to use the configured radius server name as the input to identify the unique server in the server group and print the server dead criteria configuration.
|
show access-session command |
The info keyword was introduced for the show access-session command.
|
Silent Host Handling |
The silent-host-detection keyword was introduced for the following commands:
|
Support for RFC8781 - PREF64 in IPv6 RA |
Introduces the ipv6 nd ra nat64-prefix command to configure NAT64 prefix information in an IPv6 router advertisement (RA) on an interface. This feature can be enabled only if NAT64 is already configured on the device. |
TCN Flood |
The no ip igmp snooping tcn flood command was introduced to disable the flooding of multicast traffic during a spanning-tree Topology Change Notification (TCN) event.
|
New on the WebUI |
|
There are no new WebUI features in this release. |
Behavior Change |
Description |
---|---|
Deprecation of snmp-server enable traps license global configuration command |
The command was deprecated. The associated MIB, CISCO-LICENSE-MGMT-MIB, is also no longer supported. In place of the deprecated command and unsupported MIB, use CISCO-SMART-LIC-MIB. On devices where In-Service Software Upgrade (ISSU) is supported, before you perform an ISSU upgrade, you must manually remove the snmp-server enable traps license global configuration command if it is present in startup configuration. If the command is present in the configuration during an ISSU upgrade, it causes an ISSU configuration synchronization failure. Enter the no form of the command to remove it from the configuration and save changes by entering the copy running-config startup-config command in privileged EXEC mode. |
New flag for the IPv6 SGACL monitor mode |
A new flag has been introduced for the IPv6 SGACL monitor mode. This was introduced to address hardware limitation of a single counter shared for IPv4 and IPv6 traffic. The HW_Monitor counter gets incremented irrespective of the type of traffic, which in turn updates the monitor mode flag. With a separate flag for IPv6 and IPv4 SGACL monitor mode, only the corresponding protocol flag is updated depending on the type of traffic. |
show power and show power detail command output |
The show power and show power detail command outputs are modified to display the correct power information of the standby switch. |
