H3C-STP -TC
Core Switch Error Reporting:
Instance 0's port Bridge-Aggregation72 was notified a topology change.
Reasons:
一般是二层交换机上的端口一直up/down导致网络中发生了stp拓扑变化，端口向上通报网络拓扑发生变化
resolution：
1.全局开启BPDU保护：stp bpdu-protection
2.不参与STP计算的端口开启边缘端口：stp edged-port
若还有大量BPDU TC，可能是stp模式不一致导致的，尤其是不同厂商间的交换机的默认stp模式不同，不兼容导致的

收到了TC报文，说明网络有拓扑变化，看下接终端的端口是否配置边缘端口，是否有端口频繁UP/DOWN
TC报文日志提醒，说明聚合50 70口对端设备有端口UP DOWN
这是STP TC报文提示的拓扑改变，以下是排查要点，请参考：
1、检查端口是否频繁UP DOWN
2、检查物理链路是否有问题。
3、检查主根是否稳定。
4、登录到对端设备看是否也有上述情况
如果经常出现这类的日志，且很频繁，STP的TC报文过多，可能会出现STP TC震荡从而影响到业务，以下是排查要点，请参考：
1、终端接入的端口可开启STP边缘端口，以下是参考命令：
int gi 1/0/1
stp edge-port enable
quit
2、检查设备之间、设备到终端的物理链路是否有问题。
3、检查STP根桥是否稳定，可在根桥的下行端口开启STP根保护。
4、使用dis stp tc看下哪些端口在TC报文收、发统计在增长，增长频繁的，根据端口去往对端设备上进一步排查。
5、如果对端设备无法管理到或不是管辖的范围，可考虑开启STP TC保护。
在系统视图下开启bpdu保护，如果不开启此功能，边缘端口收到bpdu报文（比如收到bpdu攻击的时候）会转变为非边缘端口，开启bpdu保护后，再收到bpdu报文，stp将关闭该端口，系统视图下：
stp bpdu-protection
交换机开启了stp环路保护协议，当参与stp计算的端口发生up/down时，就会TC报文，通知相邻网桥拓扑发生变化，如果你这个端口连接的是服务器或者是终端，可以再端口下关闭stp或者设置成边缘端口，就不会再有这个提示了
int g1/0/1
undo stp en 端口视图下关闭stp
int g1/0/1
stp edged-port 开启边缘端口

2. 2 配置日志信息保存到日志文件
通过配置日志信息保存到日志文件，用户可以将系统产生的日志信息保存到设备的日志文件中以便随时查看。
日志在保存到日志文件前，先保存在日志文件缓冲区。
系统会按照指定的频率将日志文件缓冲区的内容写入日志文件，频率一般配置为24小时一次，在设备比较空闲的时候（比如清晨）进行保存，用户也可以手工触发保存。成功保存后，保存前的日志文件缓冲区里的内容会被清空。
日志文件有容量限制，当日志文件的大小达到最大值，且日志文件写满保护功能处于关闭状态，系统会自动创建logfile1.log来存储日志。logfile1.log写满后，会被压缩成logfile1.log.gz，再自动创建logfile2.log来存储日志。logfile2.log写满后，会被压缩成logfile2.log.gz，再自动创建logfile3.log来存储日志，以此类推。
当日志文件的个数达到设备支持的最大值时，系统会找出生成时间最早的压缩文件（例如为logfileX.log.gz），并创建一个同名日志文件（logfileX.log）来存储日志，logfileX.log写满后，会被压缩成logfileX.log.gz来替换现有的logfileX.log.gz，以此类推。建议及时备份日志文件和日志压缩文件，以免重要日志被覆盖。
日志文件有容量限制，当日志文件的大小达到最大值，且日志文件写满保护功能处于开启状态，不再覆盖旧日志或旧日志文件，而是停止记录日志。
配置日志信息保存到日志文件
| 操作 | 命令 | 说明 | |
|---|---|---|---|
| 进入系统视图 | system-view | - | |
| 开启信息中心 | info-center enable | 缺省情况下，信息中心处于开启状态 | |
| 开启保存日志文件功能 | info-center logfile enable | 缺省情况下，允许日志信息输出到日志文件 | |
| （可选）开启日志文件写满保护功能 | info-center logfile overwrite-protection [ all-port-powerdown ] | 缺省情况下，日志文件写满保护功能处于关闭状态本命令仅FIPS模式下支持 | |
| （可选）配置单个日志文件最大能占用的存储空间的大小 | info-center logfile size-quota size | 缺省情况下，单个日志文件最大能占用的存储空间为5MB为了保证设备的正常运行，info-center logfile size-quota配置的日志文件的大小最小不能低于1MB，最大不能超过5MB | |
| （可选）配置存储日志文件的目录 | info-center logfile directory dir-name | 缺省情况下，存储日志文件的目录为flash:/logfile配置会在设备重启或主从设备倒换后失效 | |
| 将日志文件缓冲区中的内容保存到日志文件 | 配置自动保存的频率 | info-center logfile frequency freq-sec | 二者选其一缺省情况下，系统自动保存日志文件的频率为86400logfile save命令在任意视图均可执行 |
dis diagnostic-information
收集设备诊断信息，包含配置、路由、接口、硬件、软件、设备日志、运行状态等信息，一般用于设备故障时收集的。
如果要导出诊断信息文件，先使用dir命令查看诊断信息的文件名，通过ftp或TFTP及3CDROM软件进行导出。
路由-->汇聚-->二层-->终端，顺着往下排查，接终端的交换机接口开启边缘端口
STP的TC报文过多，可能会出现STP TC震荡从而影响到业务
1、终端接入的端口可开启STP边缘端口：
int gi 1/0/1
stp edge-port enable
quit
2、检查设备之间、设备到终端的物理链路是否有问题。
3、检查STP根桥是否稳定，可在根桥的下行端口开启STP根保护。
4、使用dis stp tc看下哪些端口在TC报文收、发统计在增长，增长频繁的，根据端口去往对端设备上进一步排查。
5、如果对端设备无法管理到或不是管辖的范围，可考虑开启STP TC保护。
频繁刷新mac地址表，会占用设备资源
会刷新开启了stp设备的mac地址和arp ，会造成2层流量泛洪和转发延迟
建议在交换机末端开启STP功能，及边缘短端口功能，可以减少或防止环路带来的影响。在其端口下：如int g1/0/1后stp edged-port
另外，在系统视图下开启bpdu保护，如果不开启此功能，边缘端口收到bpdu报文（比如收到bpdu攻击的时候）会转变为非边缘端口，开启bpdu保护后，再收到bpdu报文，stp将关闭该端口，系统视图下：
stp bpdu-protection
交换机开启了stp环路保护协议，当参与stp计算的端口发生up/down时，就会TC报文，通知相邻网桥拓扑发生变化，如果你这个端口连接的是服务器或者是终端，可以再端口下关闭stp或者设置成边缘端口，就不会再有这个提示了
int g1/0/1
undo stp en 端口视图下关闭stp
int g1/0/1
stp edged-port 开启边缘端口

收到了TC报文，说明网络有拓扑变化，看下接终端的端口是否配置边缘端口，是否有端口频繁UP/DOWN
TC报文日志提醒，说明聚合50 70口对端设备有端口UP DOWN
这是STP TC报文提示的拓扑改变，以下是排查要点，请参考：
1、检查端口是否频繁UP DOWN
2、检查物理链路是否有问题。
3、检查主根是否稳定。
4、登录到对端设备看是否也有上述情况
