Track项与接口的关系说明

Track项与接口的关系说明

关于防火墙track项与接口之间的关系主要是有下面三条命令进行配合。

1.       track track-entry-number interface interface-type interface-number

2.       track track-entry-number interface interface-type interface-number physical

3.       track track-entry-number interface interface-type interface-number protocol { ipv4 | ipv6 }

可以通过display interface interface-type interface-number的来查看对应接口的链路状态

[H3C]display interface Ten-GigabitEthernet 2/0/6

Ten-GigabitEthernet2/0/6

Current state: UP

Line protocol state: DOWN(LAGG)   （链路聚合的非选中端口）

Description: Ten-GigabitEthernet2/0/6 Interface

Bandwidth: 10000000 kbps

Maximum transmission unit: 1500

Allow jumbo frames to pass

Broadcast max-ratio: 100%

Multicast max-ratio: 100%

Unicast max-ratio: 100%

Internet protocol processing: Disabled

track track-entry-number interface interface-type interface-number

命令用来创建与指定接口链路状态关联的Track项

当对应的接口下Line protocol state为DOWN时，对应的track项则为negative

[H3C]track 111 interface Ten-GigabitEthernet 2/0/6

[H3C]display track 111

Track ID: 111

  State: Negative

  Duration: 0 days 0 hours 0 minutes 56 seconds

  Tracked object type: Interface

  Notification delay: Positive 0, Negative 0 (in seconds)

  Tracked object:

    Interface: Ten-GigabitEthernet2/0/6

Protocol: None

track track-entry-number interface interface-type interface-number physical

命令用来创建与指定接口物理状态关联的Track项

[H3C]track 112 interface Ten-GigabitEthernet 2/0/6 physical

[H3C]display track 112

Track ID: 112

  State: Positive

  Duration: 0 days 0 hours 2 minutes 24 seconds

  Tracked object type: Interface

  Notification delay: Positive 0, Negative 0 (in seconds)

  Tracked object:

    Interface: Ten-GigabitEthernet2/0/6

Protocol: None

track track-entry-number interface interface-type interface-number protocol { ipv4 | ipv6 }

命令用来创建与指定接口网络层协议状态关联的Track项

Track ID: 113

  State: Negative

  Duration: 0 days 0 hours 9 minutes 14 seconds

  Tracked object type: Interface

  Notification delay: Positive 0, Negative 0 (in seconds)

  Tracked object:

    Interface: Ten-GigabitEthernet2/0/6

Protocol: IPv4

如果接口配置了ipv4地址，且Current state和Line protocol state都是UP状态的话，对应的track项将是Positive状态；如果Line protocol state是down的话，无论是否配置了ipv4地址，对应的track项都是Negative状态。
