1、由于2槽位业务板和10槽位网板间互联HG频繁UP/DOWN，业务检测报文会经错HG UP/DOWN的内联口，因此也出现slot 2、slot 3、slot 6单板在报业务检查异常告警。

2、因此需要分析slot 2和slot 10网板单板之间HG DOWN UP原因，从新收集如下信息确定，2槽位业务板侧存在较多不可纠错FEC计数，收集三次，每次读清后还会产生：
[S12608G-probe]dis hardware internal port hg-monitor slot 2
Fec Counter Record:
[uiLlogicport] [Correct] [Uncorrect] [Clock] [Number]
==================================================================================
UpLinkPort_274 21669 391 03:58:32:711797 01/20/2026 1
UpLinkPort_274 1177 101 03:59:15:170891 01/20/2026 2
UpLinkPort_274 61202 1337 04:03:17:873256 01/20/2026 3
UpLinkPort_274 134 11 04:06:45:534417 01/20/2026 4
网板侧正常：
[S12608G-probe]dis hardware internal port hg-monitor slot 10
Fec Counter Record:
[uiLlogicport] [Correct] [Uncorrect] [Clock] [Number]
==================================================================================
UpLinkPort_267 0 0 03:59:19:576707 01/20/2026 1
UpLinkPort_267 0 0 04:03:22:848997 01/20/2026 2
UpLinkPort_267 0 0 04:06:49:787219 01/20/2026 3
根据FEC计数情况来看，分析是2槽位业务板侧的问题。
更换2槽位业务板。
注：类似问题，国芯设备需要收集的命令如下，以本次2槽位和10槽位直接HG/DOWN为例：
1、收集下如下命令，间隔3分钟读取一次，读取3次：
sys
prob
dis clock
dis hardware internal port hg-monitor slot 2
dis hardware internal port hg-monitor slot 10
2、确定内部互联口关系，然后收集内部互联口信息：
====display devm hgport chassis 0 slot 2====
(slot 2, slot 10):
Slot 2 connect Slot 10
Lindex (Lchip, Lport, Gport) | Lindex (Lchip, Lport, Gport)
274 (2 , 30 ,0xe1e ) | 267 (0 , 6 ,0x1e06)
Sys
Prob
sdk slot 2 sdk
sdk slot 2 enter/lchip/2
sdk slot 2 show/port/0xe1e/all
sdk slot 2 port/0xe1e /self-checking
收集完上述槽位后，退出到系统系统，再次进入probe收集：
Sys
Prob
sdk slot 10 sdk
sdk slot 10 enter/lchip/0
sdk slot 10 show/port/0x1e06/all
sdk slot 10 port/0x1e06/self-checking
