Eu tenho dois switches idênticos da Camada 3, executando versões idênticas do Cisco IOS. Um dos switches, eu posso configurar com o ipv6. O outro switch no entanto, diz-me "Comando não reconhecido" quando eu tento qualquer comando ipv6. Isso inclui comandos dentro de uma interface Vlan, e não apenas configurações gerais do ipv6.
Bom interruptor:
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 incorreto:
ns-sw04#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ns-sw04(config)#ipv6 ?
% Unrecognized command
A resposta óbvia para a pergunta é "Seu switch não suporta o Conjunto de recursos IPv6", mas isso não faz sentido porque o firmware e o IOS são idênticos em ambos os switches.
Bom interruptor:
