Instructions

目标

1.
重点 2.配置 LLDP
2。查看 LLDP 配置
4。查看相邻LLDP代理公告的信息

 

要点

  • 从固件版本9.2.0.2开始，默认启用LLDP。以前版本的LLDP默认被禁用。
  • Dell Networking系统的每个接口支持多达八个邻居。
  • 每个Dell Networking系统总共支持最多8000个邻居。如果接口数量乘以八超过此最大值，系统不会配置超过8000。
  • 接口级别配置覆盖所有配置级别配置。

 

配置LLDP
 

命令

目的

FTOS# configure

输入配置模式。

FTOS(config)# protocol LLDP

进入LLDP模式。

FTOS(config-lldp)# no disable

Disable将全局关闭LLDP。No disable将全局开启LLDP。由于协议引入时处于disabled（禁用）状态，该语句的否定形式将开启此协议。

FTOS(conf-if-te-0/10)#protocol lldp

在接口级别找到相同的LLDP模式。所有特定接口级别LLDP模式命令覆盖任何全局配置的LLDP参数。

 

查看LLDP配置

 

Dell(conf)# protocol lldp

Dell(conf-lldp)# show config
!
protocol lldp
advertise dot1-tlv port-protocol-vlan-id port-vlan-id
advertise dot3-tlv max-frame-size
advertise management-tlv system-capabilities system-description hello 10
no disable

Dell(conf-lldp)# exit

Dell(conf)# interface gigabitethernet 1/31

Dell(conf-if-gi-1/31)# show config
!
interface GigabitEthernet 1/31
no ip address
switchport
no shutdown
Dell(conf-if-gi-1/31)# protocol lldp

Dell(conf-if-gi-1/31-lldp)# show config
!
protocol lldp

查看相邻LLDP代理公告的信息
 

显示有关相邻设备的简要信息。

show lldp neighbors

显示邻居正在通告的所有信息。
