Dell Networking PowerSwitch 第 1 层光纤故障处理

Summary: 本指南旨在提供在以太网交换机中使用收发器时,对第 1 层连接问题进行故障处理的一般指南。

Instructions

这适用于第 1 层连接,如果链路显示“up/up”,但预期流量未传递,则可能存在其他配置问题。
 

物理因素

验证两端的收发器和线缆是否已正确就位且右侧朝上。

验证这些部件是否相互兼容。例如,单模光纤在多模收发器中不起作用。

验证收发器和线缆是否处于良好的工作状态。换用已知良好的组件后是否正常工作?如果使用连接远端的不同设备,它是否正常工作?交换机上配置不同的相同端口?

验证收发器是否适用于正在使用的交换机和作系统版本。戴尔支持或销售人员可以帮助验证收发器是否合格。戴尔不保证第三方或不合格的光纤能够可靠地工作,或根本无法工作。 

配置注意事项

链路上的端口速度、协商和 FEC 设置必须匹配。例如,如果在自动协商关闭的情况下将服务器节点设置为 10G,则交换机应与此匹配。 

如果无法验证远端的设置,或者链路未启动,请浏览界面上的可用设置。

有关确切的命令语法,请参阅作系统版本的用户指南,但下面是一些一般准则:
 

声音的:

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:
(请注意,对于 S5200F-ON 和某些 Z 系列交换机,速度会因端口组设置而发生变化,请参阅 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 设置:

有时需要手动设置 FEC 设置,但通常默认的“自动”模式就足够了。此设置必须在整个链路上匹配。这仅适用于 25G、50G 或 100G 以太网接口。

声音的:

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
