Tengo dos conmutadores de capa 3 idénticos, que ejecutan versiones idénticas de Cisco IOS. Uno de los interruptores, puedo configurarlo con ipv6. Sin embargo, el otro modificador me dice "Comando no reconocido" cuando pruebo cualquier comando ipv6. Esto incluye comandos dentro de una interfaz Vlan, y no solo la configuración general de ipv6.
Buen cambio:
ns-sw03#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ns-sw03(config)#ipv6 ?
access-list Configure access lists
cef Cisco Express Forwarding for IPv6
dhcp Configure IPv6 DHCP
general-prefix Configure a general IPv6 prefix
hop-limit Configure hop count limit
host Configure static hostnames
icmp Configure ICMP parameters
local Specify local options
mld Global MLD Snooping enable for Catalyst Vlans
nd Configure IPv6 ND
neighbor Neighbor
ospf OSPF
prefix-list Build a prefix list
route Configure static routes
router Enable an IPV6 routing process
source-route Process packets with source routing header options
traffic Configure traffic parameters
unicast-routing Enable unicast routing
Interruptor malo
ns-sw04#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ns-sw04(config)#ipv6 ?
% Unrecognized command
La respuesta obvia a la pregunta es "Su conmutador no es compatible con el conjunto de características IPv6", pero esto no tiene ningún sentido porque el firmware y el IOS son idénticos en ambos conmutadores.
Buen cambio:
