2960交换机使用ipv6

请问2960交换机开启ipv6有什么要求吗,是否要哪个高版本ios? 

ipv6是否仅支持3层交换机开启路由模式?二层交换机的管理vlan的ip地址能设置为ipv6吗?

12.2(50)应该是支持配置IPv6的,不过默认情况下ipv6并未启用,需要手动开启一下

全局模式下配置"sdm prefer dual-ipv4-and-ipv6 default",然后重启交换机,即可使用ipv6,

2960作为基础的二层交换机,支持ipv6的功能也是有限的,接口SVI配置v6地址,配置单播的默认路由还是可以的,其他的就有点鸡肋了。更多的Feature可以参考一下文档:

2960的产品大部分已经EOS了,如果还有在使用的设备,建议将相关的文档下载一些进行留存。
