锐捷交换机18010-X端口假死现象

一次上架锐捷交换机，由于ODF光衰不稳定，导致交换机端口down，排查很多发现以下故障：

重置18010-X端口发现提示一下命令：

Port in violation! Use 'errdisable recovery' command to up the port!

 

 

gz-sprine1#show interfaces tenGigabitEthernet 4/5 status

Interface Status Vlan Duplex Speed Type

---------------------------------------- -------- ---- ------- --------- ------

TenGigabitEthernet 4/5 disabled routed Unknown Unknown fiber

 

修改 err为30s: errdisable recovery interval 30

恢复出错的端口：errdisable recovery cause link-state

 

重新检查交换机的状态，恢复正常。

gz-sprine1#show interfaces tenGigabitEthernet 4/5 st

gz-sprine1#show interfaces tenGigabitEthernet 4/5 status

Interface Status Vlan Duplex Speed Type

---------------------------------------- -------- ---- ------- --------- ------

TenGigabitEthernet 4/5 down routed Unknown Unknown fiber

gz-sprine1#

 

备注：端口处于error状态，端口不会发光，技术上称为假死。
