Cisco nexus 3048 SFP验证失败

Question

我有cisco Nexus 3048交换机(48x1G + 4x10G)

Hardware
  cisco Nexus 3048 Chassis ("48x1GE + 4x10G Supervisor")
  Intel(R) Celeron(R) CPU        P4505  @ 1.87GHz with 3665240 kB of memory.
  Processor Board ID FOC17237JKC

我在端口e1/49上看到了这个错误，它是10G端口，我已经连接了10G SFP+收发器。

 Ethernet1/49 is down (SFP validation failed)
     Dedicated Interface
      Hardware: 1000/10000 Ethernet, address: f872.eaae.36b8 (bia f872.eaae.36b8)
      MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec
      reliability 255/255, txload 1/255, rxload 1/255
      Encapsulation ARPA
      Port mode is access
      auto-duplex, 10 Gb/s, media type is 10G

根据文档，他们说您需要设置speed，所以我做了，并得到了这个错误

n3k(config)# int e1/49
n3k(config-if)# speed 10000
ERROR: Ethernet1/49: Configuration does not match the port capability.

这个开关位于远程数据中心，所以在我有可用的资源之前我不能重新启动，还有什么我可以远程做的吗？

Answer 1

解决：

在重新启动开关之后，它修复了我的问题，现在它显示了SFP Type 10Gbase-SR

n3k# show int e1/49 capabilities
Ethernet1/49
  Model:                 N3K-C3048TP-1GE-SUP
  Type (SFP capable):    10Gbase-SR
  Speed:                 10000
  Duplex:                full
  Trunk encap. type:     802.1Q
  Channel:               yes

看起来，在插入SFP之前，需要先设置speed。
