PortIndex MSTP的端口索引。 IfIndex 端口索引。 PortName 端口名称。 PwName PW名称。 可能原因 原因1:配置了根保护的指定端口收到了比本桥优先级高的BPDU报文。原因2:网络拓扑有设备优先级发生变化。 处理步骤 原因1:The port enabled with the root protection function received BPDUs of a higher priority th...
PortID 端口ID。 可能原因 原因1:新加入了设备,该设备的桥ID最优。原因2:修改了原有网络中设备的优先级或域配置。 处理步骤 原因1:A new device was added, which had the optimal bridge ID. 1. 请检查新加入的物理链路是否是需要的物理链路。 如果是需要的物理链路,则请执行步骤2。 如果不是需要的物理...

4. If the received Spanning Tree Port Priority value values are the same between the connecting ports to reach the Root Bridge (Root Switch), Non-Root Switch will select the port which receives the lowest physical port number from neighbor Switch as the Root Port. Consider the sit...
When determining the root port for a non-root switch, how does STP decide which interface to select when the sender port id is the same? In this case, SW1 is the root. [SW1]---[Hub]===[SW2] Output on SW2: Port 2 (GigabitEthernet0/1) of VLAN0001 is root forward...
%SPANTREE-2-ROOTGUARDBLOCK: Port 1/1 tried to become non-designated in VLAN 77. Moved to root-inconsistent state 注意,在一个端口上起用了根保护,会作用于该端口所属的所有VLAN。不要再一个起用了UplinkFast特性的端口上启用根保护。游乐UplinkFast,在出现故障时备份端口(处于阻塞状态)会代替根端口。但是...
The method has the steps of: setting a port of the switch to root guard protected status (RG status); selecting by a spanning tree protocol (STP) the port as a designated port; and setting said port into blocked status, in response to said port being both in root guard protected status...
elect a new STP root. Instead, root guard puts the port into the root-inconsistent STP state. You must enable root guard on all ports where the root bridge must not appear. In a way, you can configure a perimeter around the part of the network where the STP root is able to be ...
