连接到Cisco交换机的数据端口出现CRC错误
适用场景
- FAS 系统
- AFF系统
- Cisco 交换机上的端口
- Active IQ Digital Advisor
问题描述
- 收到Active IQ风险警报:
Risk: This system has a high count of CRC errors accumulated on at least one data network port that should be investigated.
Description: This system has CRC errors on data port e0e.
Impact: High CRC errors counts, or link resets can result in packet loss and are typically caused by physical defects in the port, SFP, or cables
- 此端口已连接到数据交换机
IFSTAT-A
部分AutoSupport或cluster::> ifstat -a
显示CRC错误:

- 两侧都更换了SFP
- 已更换节点和交换机之间的缆线
- 此时将清除节点端口上的统计信息、并返回CRC错误
