Hola @JonathanRodrigoGomezHuerta5994
Te comparto lo que pude encontrar.
En esta guía se indica que se puede actualizar la licencia:
Este link te dirige a la lista de licencias:
He buscado la de 3 años y en varios sitios cuesta unos 7000 dólares.
Te sugiero contactar con un partner de Cisco de tu localidad para averiguar los precios que manejan ellos.
Espero que eso te sea de utilidad.
Saludos
Hola
Adjunto los requerimientos de stackwise, en algunos modelos se requiere que la version del IOS sea de los mas recientes, como menciona Luis, si haces el upgrade de licencia DNA debes contactar aun Cisco partner quien te puede ayudar con el proceso, y brindarte el precio.
Basado en la documentacion, si es requerido DNA Advantage para completar el stackwise: https://community.cisco.com/t5/switching/cat-9500-40x-stackwise-virtual-only-on-network-advantage/td-p/3368943
StackWise Virtual is an advanced stacking technology that supports both core and distribution deployments through multiple topologies. It provides higher scale for system virtualization at the network layer. The Cisco Catalyst 9500 Series with Network Advantage License supports StackWise Virtual with a 2-node topology.
All the switches in a Cisco StackWise Virtual solution must be of the same switch model.
All the switches in a Cisco StackWise Virtual solution must be running the same license level.
All the switches in a Cisco StackWise Virtual solution must be running the same software version.
 Note |
When you enable Cisco StackWise Virtual on the device:
|
The Federal Information Processing Standards (FIPS) is not supported on Cisco StackWise Virtual links.
Cisco StackWise Virtual is supported only on the following models:
C9500-24Q
C9500-12Q
C9500-40X
C9500-16X
When configuring StackWiseVirtual links (SVLs) on 9500-40X and C9500-16X models of the Cisco Catalyst 9500 Series Switches, note that you cannot create SVLs on any of the network modules.
4x10G breakout cables are not supported with SVLs.
When deploying Cisco StackWise Virtual, ensure that VLAN ID 4094 is not used anywhere on the network. All inter-chassis system control communication between stack members is carried over the reserved VLAN ID 4094 from the global range.
The dual active and StackWise Virtual link configuration must be performed manually and the device should be rebooted for the configuration changes to take effect.
Only Cisco Transceiver Modules are supported.
The interface VLAN MAC address that is assigned by default, can be overridden using the mac-address command. If this command is configured on a single SVI or router port that requires Layer 3 injected packets, all other SVIs or routed ports on the device also must be configured with the same first four most significant bits (4MSB) of the MAC address. For example, if you set the MAC address of any SVI to xxxx.yyyy.zzzz, set the MAC address of all other SVIs to start with xxxx.yyyy. If Layer 3 injected packets are not used, this restriction does not apply.
