Catalyst 2960 重启?

时间:2024-03-04 15:21:21

在实际的网络环境中,交换机的各种问题层出不穷,这里我遇到一个案例。关于Cisco 2960  S 交换机重启的问题。

故障描述:有那么几台C2960S交换机总是随机的重启。

原因:从show ver来看,可以看到是由于power-on。

实际问题:而实际导致交换机重启的原因并不是power-on,甚至这里没有一个crashinfo的生成。

 

关于这个问题,在思科官网能找到类似的问题,但是是一个bug:

2960S silent reload with "System returned to ROM by power-on"
CSCtr78622
 
Description
Symptom:

A 2960S may reload without generating a crash file and reload reason is
reported as "System returned to ROM by power-on".

Conditions:

This issue is observed in Catalyst 2960S platform running 12.2(53)SE2.

Workaround:

None.

This bug is under investigation.

Further Problem Description:

CSCtg09555 should report more detailed reload information.
 

问题延伸,该问题可能不只是C2960S的问题,其他的型号也有类似的问题,例如如下的Bug:

2960x randomly reloads due to power-on

Description
Symptom:

There is no crashinfo written. Reload reason is "power-on".

Conditions:
Only PoE models are affected.

Workaround:
None.

Further Problem Description:
终结的意思可能是该问题已经通过换硬件解决了,没有通过配置或者软件的升级去解决这个问题。

这应该算是一个严重的错误了。不知该问题后续是否有fixed版本。
