Si tenemos un stack de 2960s, se nos rompe un switch y tenemos que cambiarlo por un 2960x tenemos que seguir el siguiente proceso
1.- Mismo IOS, tenemos que actualizar los 2960s a una versión igual a la que tengan o la que queramos que tegan los 2960x, lo cual requiere un reboot
2.- Misma plantilla, se comprueba que plantilla están corriendo con show sdm prefer. Si hay que cambiarla
2960s#show sdm preferThe current template is "desktop default" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.
number of unicast mac addresses: 6K
number of IPv4 IGMP groups + multicast routes: 1K
number of IPv4 unicast routes: 8K
number of directly-connected IPv4 hosts: 6K
number of indirect IPv4 routes: 2K
number of IPv4 policy based routing aces: 0
number of IPv4/MAC qos aces: 0.5K
number of IPv4/MAC security aces: 1K
2960s(config)#sdm prefer ?
access Access bias
default Default bias
dual-ipv4-and-ipv6 Support both IPv4 and IPv6
routing Unicast bias
vlan VLAN bias
access Access bias
default Default bias
dual-ipv4-and-ipv6 Support both IPv4 and IPv6
routing Unicast bias
vlan VLAN bias
por ejemplo la dejamos con default
2960s(config)#sdm prefer default
requiere un reinicio
3.-
Puerto de stack forzado a 10Gb/s en el 2960x (switch stack port-speed 10),
require tercer reboot
2960x(config)#switch stack port-speed 10
ya los podemos unir

By “low thermal resistance,” we mean the supplies are prone to melting if you expose them to high temperatures. CNC Toddler Mittens plasma cutting machines also supply a high degree of cutting accuracy and extensive range|a variety} of fabric compatibility, like laser cutters. They solely differ from laser cutters by performing cutting operations using a plasma torch. CNC routers are very similar to|similar to} CNC millsㅡthey use a multi-blade cutting tool that rotates towards the workpiece to create desired elements. However, while CNC mills are commonly used for hard metals and industrial-grade supplies, CNC routers are higher fitted to cutting softer and delicate supplies like plastics, wooden, and foam.
