问题描述
NE80E 1/0/0GE口配置IPV6地址和NE20-4互连,但是出现1/0/1接口链路层down,能ping通对端问题,如下:

告警信息

处理过程
正确的看配置IPV6地址的接口链路层是否UP的命令如下:
[GDSZH-BC-RT001-CNGI-NE80E]display ipv6  inter gi 1/0/1                         
GigabitEthernet1/0/1 current state : UP ,                                       
Line protocol current state : UP                                                
IPv6 is enabled, link-local address is FE80::2E0:FCFF:FE00:D001                 
  Global unicast address(es):                                                   
    2001:E80:CE00:1::9, subnet is 2001:E80:CE00:1::/122                         
  Joined group address(es):                                                     
    FF02::1:FF00:9                                                              
    FF02::1:FF00:D001                                                           
    FF02::2                                                                     
    FF02::1                                                                     
  MTU is 1500 bytes                                                             
  ND DAD is enabled, number of DAD attempts: 1                                  
  ND reachable time is 30000 milliseconds                                       
  ND retransmit interval is 1000 milliseconds                                   
  Hosts use stateless autoconfig for addresses                                  
[GDSZH-BC-RT001-CNGI-NE80E]                                                     
从上输出该IPV6接口链路层是UP的,因此出现可以ping通对端。
根因
命令使用错误,实际上GE1/0/1接口IPV6的链路层还是UP的。
建议与总结
正确使用命令。
