Nexus:hardware type changed to No-Transceiver

如下是相关的案例:

1、N5K & Cat3750

较新版本的NX-OS在N5K上支持1G或10G,但N5K不支持auto-speed sensing

如下是故障信息的体现:3750和N5K之间安装GLC-SX-MM模块并连接,在3750上看了相关状态,出现了这个错误:

Description: Gi1/1/1: This port has been disabled because Non Compliant  Gigabit Interface Converter (GBIC) connector detected.

(此端口已被禁用,因为检测到非兼容千兆位接口转换器(GBIC)连接器。)

Recommendation: Replace connector with cisco compliant Gigabit Interface Converter (GBIC) connector. Refer switch technical documentation to determine cisco compliant connector. Enable the port again.

使用符合cisco标准的千兆位接口转换器(GBIC)连接器替换连接器。 请参阅交换机技术文档以确定符合cisco的连接器。 再次启用端口。

 

操作如下

①两个设备都支持GLC-SX-MM

②尝试shu/no shu接口

③Cat3750上体现的log:

*Apr  16 01:48:41.190: %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/1/1 is not supported
*Apr  16 01:48:41.190: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/1/1, putting Gi1/1/1 in err-disable state

④查看接口(支持GLC-SX-MM,接口下显示信息也OK)

3750_sw1#sh int gig 1/1/1 capa
GigabitEthernet1/1/1
  Model:                 WS-C3750X-48P
  Type:                  1000BaseSX SFP

                         tx-(4q3t) (3t: Two configurable values and one fixed.)

  SPAN:                  source/destination
  PortSecure:            yes

  Dot1x:                 yes
3750_sw1#

⑤但是3750的状态是not connect

3750_sw1#sh int gig 1/1/1 status

Port      Name               Status       Vlan       Duplex  Speed Type
Gi1/1/1                      notconnect   1            auto   auto 1000BaseSX SFP
3750_sw1#

⑥查看N5K上接口状态和信息:

N5K1# sh int e1/5 status

--------------------------------------------------------------------------------
Port          Name               Status    Vlan      Duplex  Speed   Type
--------------------------------------------------------------------------------
Eth1/5        --                 sfpInvali 1         full    10G     SFP-1000BAS
N5K1#
N5K1# sh int e1/5 capa
Ethernet1/5
  Model:                 N5K-C5548UP-SUP
  Type (SFP capable):    10Gbase-(unknown)
  Speed:                 1000,10000
  Duplex:                full
  Trunk encap. type:     802.1Q
  Channel:               yes
  Broadcast suppression: no
  Flowcontrol:           rx-(off/on),tx-(off/on)
  Rate mode:             none
  QOS scheduling:        rx-(6q1t),tx-(1p6q0t)
  CoS rewrite:           no
  ToS rewrite:           no
  SPAN:                  yes
  UDLD:                  yes
  Link Debounce:         yes
  Link Debounce Time:    yes
  MDIX:                  no
  Pvlan Trunk capable:   yes
  TDR capable:           no
  FabricPath capable:    yes
  Port mode:             Switched
  FEX Fabric:            yes

N5K1#

其实这里应该看到N5K和Cat3750之间的speed不匹配。

⑦查看N5K的log

N5K1#sh log | inc 1/5
...
2019 Apr 6 18:10:26 N5K1 %ETHPORT-5-IF_DOWN_NONE: Interface Ethernet1/5 is down (None)
...
2019 Apr 6 19:06:10 N5K1 %ETHPORT-5-IF_HARDWARE: Interface Ethernet1/5, hardware type changed to No-Transceiver

⑧在N5K手动设置速度

N5K1# sh int e1/5 stat

--------------------------------------------------------------------------------
Port          Name               Status    Vlan      Duplex  Speed   Type
--------------------------------------------------------------------------------
Eth1/5        --                 connected 1         full    1000     SFP-1000BAS
N5K1#

可以看到修改后正常了。

Summary: The newer versions of NX-OS support 1G or 10G on the N5K, but the N5K is not auto-speed sensing. If you run into something similar, even error messages on the remote device, check the port speed on the N5K.
