我們可以在SRX設(shè)備上先使用如下命令，你應(yīng)該可以看到以下輸出的這些信息：
root@srx> show security flow status
Flow forwarding mode:
Inet forwarding mode: flow based
Inet6 forwarding mode: drop
MPLS forwarding mode: drop
ISO forwarding mode: drop
Flow trace status
Flow tracing status: off
Flow session distribution
Distribution mode: RR-based
從上面輸出的信息，我們可以知道Inet6默認(rèn)是drop的，如果要啟用inet6的，我們可以使用這個命令：
#set security forwarding-options family inet6 mode flow-based
執(zhí)行完上面的命令后，對配置進(jìn)行commit一下，設(shè)備會要求你“重啟”，重啟后，再使用這條命令查看，就可以看到Inet6已經(jīng)啟用了，是基于流模式。
root@srx> show security flow status
Flow forwarding mode:
Inet forwarding mode: flow based
Inet6 forwarding mode: flow based
MPLS forwarding mode: drop
ISO forwarding mode: drop
Flow trace status
Flow tracing status: off
Flow session distribution
Distribution mode: RR-based
PS：如果你的SRX不是流模式而是數(shù)據(jù)包模式，可以使用如下命令進(jìn)行啟用IPv6
set security forwarding-options family inet6 mode packet-based
