最佳答案
检查下配置和物理接口状态吧
日志看H3C侧异常,M-LAG同步不正常且报物理端口状态在变化
建议检查下M-LAG配置和状态、在检查物理端口、在检查聚合组以及stp相关状态

华三 思科对接STP参考:
H3C支持的STP/RSTP/MSTP均是IEEE标准组织制定的标准协议。Cisco支持的生成树协议中,MSTP为标准协议,Rapid-Pvst为Cisco私有协议。
如表4所示,H3C和Cisco生成树协议的互通性情况如下:
· H3C的MSTP与Cisco的MSTP可以完全互通
为了实现互通,在保证相连的H3C交换机域配置和Cisco交换机域配置完全一致的前提下,还需要在H3C设备上通过stp config-digest-snooping命令,在每一个和Cisco交换机相连的端口上开启摘要侦听功能功能。
另外,H3C设备的Comware V5 MSTP默认BPDU封装格式为legacy,Comware V7 MSTP默认BPDU封装格式为802.1s。在Cisco设备上需要通过spanning-tree mst pre-standard(legacy)或no spanning-tree mst pre-standard(802.1s)命令,将MSTP BPDU封装格式修改为legacy 或802.1s,使得H3C设备和Cisco设备的MSTP BPDU封装格式一致。
· H3C的MSTP与Cisco的Rapid-Pvst可以在一定程度上完成互通
如果H3C设备采用Access端口对接,H3C设备会将Cisco设备当作一个支持IEEE802.1D的设备,正常进行生成树计算。如果H3C设备采用Trunk接口对接,标准的STP设备可以与Rapid-Pvst设备的VLAN 1互通;但在其他VLAN上,标准STP设备无法识别Rapid-Pvst报文,要求物理环路必须在标准STP设备上来阻断,也就是说Blocking端口必须在标准STP设备(H3C)上而不是Rapid-Pvst设备(Cisco)上,否则就可能导致VLAN 1以外的其他VLAN出现广播风暴。
表4 MSTP/PVST互通性分析
H3C | Cisco | 互通结论 |
STP模式 | MSTP模式(Legacy和802.1s封装) | 在实例0中可以互通 |
STP模式 | Rapid-Pvst模式 | 在Cisco设备上不取消VLAN 1的Rapid-Pvst功能的情况下,可以互通 |
RSTP模式 | MSTP模式(Legacy和802.1s封装) | 在实例0中可以互通 |
RSTP模式 | Rapid-Pvst模式 | 在Cisco设备上不取消VLAN 1的Rapid-Pvst功能的情况下,可以互通 |
MSTP模式 | MSTP模式(Legacy和802.1s封装) | 在H3C设备配置stp config-digest-snooping命令的情况下,可以互通 |
MSTP模式 | Rapid-Pvst模式 | 在Cisco设备上不取消VLAN 1的Rapid-Pvst功能的情况下,可以互通 |
如图7所示,H3C设备与Cisco设备通过两条链路相互连接。现要求在H3C设备和Cisco设备上分别配置MSTP,实现MSTP互通。

为保证H3C交换机的路径开销计算标准与第三方交换机一致,需要确认第三方交换机的开销计算标准,然后在H3C交换机上进行相应的修改。
# 当Cisco设备采用缺省路径开销计算标准,H3C交换机需要配置按照IEEE 802.1D-1998标准来计算缺省路径开销。

在Cisco设备上不取消VLAN 1的Rapid-Pvst功能的情况下,可以互通。。。这个可以理解为其他vlan能通是吧,但凡我看接入交换机除vlan1的生成树根还是自己
