目標

1.
要點 2.設定 LLDP
2。檢視 LLDP 組態
4.檢視相鄰 LLDP 代理機構公佈的資訊

 

重點

  • 從韌體版本 9.2.0.2 開始，LLDP 預設為啟用。先前版本 LLDP 預設為停用。
  • Dell Networking 系統的每個介面最多可支援八個鄰近方。
  • Dell Networking 系統支援每個系統最多 8000 個總芳鄰。如果介面數乘以 8 超過最大值，則系統不會設定超過 8000。
  • 介面層級組態會覆寫所有組態層級組態。

 

設定 LLDP
 

命令

用途

FTOS# configure

進入組態模式。

FTOS(config)# protocol LLDP

進入 LLDP 模式。

FTOS(config-lldp)# no disable

停用會全域關閉 LLDP。「未停用」會全域開啟 LLDP。由於該協定是作為“禁用”引入的，因此該語句的否定數打開協定。

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

在介面級別也可以找到相同的 LLDP 模式。所有特定介面層級 LLDP 模式命令都會覆寫任何全域設定的 LLDP 參數。

 

檢視 LLDP 組態

 

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

檢視相鄰 LLDP 代理機構公佈的資訊
 

顯示相鄰裝置的簡短資訊。

show lldp neighbors

顯示鄰居正在播發的所有資訊。

show lldp neighbors detail

 

檢視鄰居宣傳的簡短資訊的範例

Dell(conf-if-te-0/3-lldp)# end

Dell (conf-if-te-0/3)# do show lldp neighbors
