Dell Networking PowerSwitch 第 1 層光學故障診斷

Summary: 本指南旨在針對在乙太網路交換器中使用傳發器時,針對第 1 層連線問題進行故障診斷提供一般指引。

Instructions

這是針對第 1 層連接的,如果鏈路顯示「啟動/啟動」,但預期的流量未通過,則可能存在其他配置問題。
 

物理注意事項

確認傳發器和纜線兩端已正確插入,且右側朝上。

確認零件彼此相容。例如,單模光纖在多模收發器中不起作用。

確認傳發器和纜線處於正常運作狀態。換入已知良好的元件時,是否正常?如果使用連接遠端的不同設備,它是否有效?交換器上的連接埠配置不同?

確認傳發器是否符合使用中的交換器和作業系統版本。Dell 支援或銷售人員可協助確認傳發器是否合格。Dell 不保證第三方或非合格光學器件能可靠運作,或完全不保證。 

組態考量

連接埠速度、交涉和 FEC 設定必須在整個鏈路上相符。例如,如果伺服器節點設為 10G 且自動交涉關閉,則交換器應與此相符。 

如果無法驗證遠端的設置,或者鏈路未出現,請運行介面上的可用設置。

請參閱作業系統版本的使用者指南,以瞭解確切的命令語法,但以下是一些一般準則:
 

SONiC:

soinc # configure terminal
sonic (conf)# interface Eth 1/1
sonic(conifg-if-Eth1/1)#  speed auto (default)
sonic(conifg-if-Eth1/1)#  no speed auto
sonic(conifg-if-Eth1/1)#   speed 10000

OS10:
(請注意 S5200F-ON 和部分 Z 系列交換器,速度會透過連接埠群組設定變更,請參閱 https://www.dell.com/support/manuals/en-us/smartfabric-os10-emp-partner/smartfabric-os-user-guide-10-5-6/port-groups-on-s5200f-on-switches?guid=guid-1a9f6680-ab7e-4cfa-9c94-96cf3b436f8c⟨=en-us)
 

To check the current configuration of a port

OS10# show running-configuration interface ethernet 1/1/1
To change settings:
OS10:#  configure terminal
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# negotiation auto (default)
OS10(conf-if-eth1/1/1)# negotiation off (to disable auto-negotiation)
OS10(conf-if-eth1/1/1)# speed 10000 (to set speed manually)
OS10(conf-if-eth1/1/1)# speed auto (to set speed to auto-negotiate)

OS9:

To check the current configuration of a port:
OS9# show running-config interface tengigabitethernet 1/1
To change settings:
OS9# configure terminal
OS9 (config) # interface tengigabitethernet 1/1
OS9(conf-if-te-1/1) # negotiation auto (default)
OS9 (conf-if-te-1/1)# no negotiation auto (to disable auto-negotiation)
OS9(conf-if-te-1/1)# speed 1000 

OS6:

To check the current configuration on OS6:
OS6 # show running-config interface tengigabitethernet 1/0/1
To change settings:
OS6 # configure terminal
OS6 (config)) interface tengigabitethernet 1/0/1
OS6 (conifg-if-Te1/0/1)# speed 10000

FEC 設定:

有時需要手動設置 FEC 設置,但通常預設的“自動”模式就足夠了。此設置必須在整個連結中匹配。這僅適用於 25G、50G 或 100G 乙太網介面。

SONiC:

sonic(config)# interface Eth1/2
sonic(config-if-Eth1/2)# fec [option]

Available options:

auto — Automatically detects an installed transceiver and configures the correct FEC type on a port.
FC — Enables FEC type FC on supported interfaces. FC stands for fire code.
RS — Enables FEC type RS on supported interfaces. RS stands for Reed-Solomon code.
none — Disables FEC on an interface.

OS10:

OS10(config)# interface ethernet 1/1/41
OS10(conf-if-eth1/1/41)# fec [option]

Available options:

CL74-FC—Supports 25G and 50G
CL91-RS—Supports 100G
CL108-RS—Supports 25G and 50G
CL119-RS—Supports 400G
off—Disables FEC

OS9:

OS9(configure)#  interface hu 1/1

OS9(conf-if-hu-1/1)#fec enable

OS6:

OS6 (conifg-if-Tw1/0/1)# forward-error-correction [option]

Available options:

disable-fec              Disable FEC
enable-fec-cl108         Enable CL108/RS FEC
enable-fec-cl74          Enable CL74/Base-R FEC
enable-fec-cl91          Enable CL91/RS FEC
inherit                  Inherit FEC
