查了一下文档,有几种可能的原因,但是都需要reload module。步骤如下:
Reinitializing a Failed Module Using the CLI
To reinitialize a failed module using the CLI, follow these steps:
1. Save the running configuration to the startup configuration.
switch# copy running-config start-config
2. Reload the module.
switch# reload module 2
3. If the module is not operating, verify the software image on the module.
switch# show module
4. If the software image on the module is not the latest, download the latest image to supervisor bootflash memory.
switch# copy tftp: bootflash:
5. Force-download the software image from the supervisor to the module.
switch# reload module 2 force-dnld
6. If the module is still not operating, verify the power status for the module.
switch# show environment power
7. If the module is not powered on, remove and reseat the module and then power on the module.
switch# config t
switch(config)# no poweroff module 2
switch(config)# exit
switch#
8. If the module is still not operating, reload the entire switch.
switch# reload
这样如果还不能解决问题,个人建议进行硬件维保吧。
