双堆栈订阅者监控和管理
监控活动订阅者会话
目的
查看活动订阅者会话的摘要。
行动
在操作模式下，输入 show subscribers summary 命令。
user@host>show subscribers summary Subscribers by State Active: 2 Total: 2 Subscribers by Client Type DHCP: 1 PPPoE: 1 Total: 2
意义
下方 Subscribers by State 输出显示活动订阅者会话数。
下方 Subscribers by Client Type 的输出按类型显示活动会话数。上面的两个订阅者会话表示 PPPoE 接入网络上的 DHCPv6 订阅者。当 DHCPv6 基于 PPPoE 分层时，会为一个订阅者创建两个独立的订阅者会话。
监控正确路由实例中的 IPv4 和 IPv6 地址
目的
验证订阅者是否同时具有 IPv4 和 IPv6 地址，以及是否放置在正确的路由实例中。
行动
在操作模式下，输入 show subscribers 命令。
user@host>show subscribers Interface IP Address/VLAN ID User Name LS:RI pp0.1073741825 203.0.113.162 ipv4-v6-subscriber default:default pp0.1073741825 2001:DB8::1 default:default
意义
字段 Interface 显示同一接口上运行了两个订阅者会话。该 IP Address 字段显示，一个会话分配了 IPv4 地址，一个会话被分配在 IPv6 地址上。
该 LS:RI 字段显示，订阅者已放置在正确的路由实例中，并且可以发送和接收流量。
监控动态订阅者会话
目的
显示动态 PPPoE 和 DHCPv6 订阅者会话。
行动
在操作模式下，输入 show subscribers detail 命令。
user@host>show subscribers detail Type: PPPoE User Name: SBRSTATICUSER IP Address: 203.0.113.162 IP Netmask: 255.0.0.0 Logical System: default Routing Instance: default Interface: pp0.1073741825 Interface type: Dynamic Dynamic Profile Name: pppoe-subscriber-profile MAC Address: 00:00:5E:00:53:01 State: Active Radius Accounting ID: 2 Session ID: 2 Login Time: 2011-12-08 09:11:41 PST Type: DHCP IPv6 Address: 2001:DB8::1 Logical System: default Routing Instance: default Interface: pp0.1073741825 Interface type: Static MAC Address: 00:00:5E:00:53:01 State: Active Radius Accounting ID: 3 Session ID: 3 Underlying Session ID: 2 Login Time: 2011-12-08 09:12:11 PST DHCP Options: len 42 00 08 00 02 0b b8 00 01 00 0a 00 03 00 01 00 01 02 00 00 01 00 06 00 02 00 03 00 03 00 0c 00 00 00 00 00 00 00 00 00 00 00 00
意义
如果通过 PPPoE 接入网络使用 DHCPv6，则输出显示 DHCPv6 订阅者会话与其底层 PPPoE 订阅者会话的关系。在 PPPoE 会话的输出中 Session ID ，为 2。DHCP 会话的输出显示为 Underlying Session ID 2。
监控用于订阅者的地址池
目的
验证用于 NDRA 的池、用于 DHCPv6 前缀委托的委托地址池以及委托给 CPE 的 IPv6 前缀的长度。
行动
在操作模式下，输入 show subscribers extensive 命令。

意义
在 PPPoE 会话下 IPv6 Delegated Address Pool ，字段显示用于 DHCPv6 前缀授权和 NDRA 前缀的池名称。字段 IPv6 Delegated Network Prefix Length 显示用于为此订阅者会话分配 IPv6 地址的前缀长度。该 IPv6 Interface Address 字段显示从 NDRA 池分配给 CPE 接口的 IPv6 地址。
在 DHCP 会话下 IPv6 Delegated Address Pool ，字段显示用于 DHCPv6 前缀授权的池的名称。字段 IPv6 Delegated Network Prefix Length 显示 DHCPv6 前缀授权中使用的前缀长度。
监控特定订阅者会话
目的
显示有关特定订阅者会话的信息。如果正在运行许多订阅者会话，则可以使用此命令显示特定会话。
行动
