Description
Protocol (MSTP), this is an external root path cost, which is the cost of the path from the
Internal Spanning Tree (IST) root (i.e. regional root) bridge to the Common Spanning Tree
(CST) root (i.e. network "global" root) bridge.
For the Common and Internal Spanning Tree (CIST) instance of the Multiple Spanning Tree
Protocol (MSTP), this is the cost of the path to the Internal Spanning Tree (IST) root (i.e.
regional root) bridge
The configured hello time from the Bridge RSTP Parameters menu.
The actual hello time provided by the root bridge as learned in configuration messages. This
time is used in designated bridges.
The configured forward delay time from the Bridge RSTP Parameters menu.
The actual forward delay time provided by the root bridge as learned in configuration
messages. This time is used in designated bridges.
The configured maximum age time from the Bridge RSTP Parameters menu.
The actual maximum age time provided by the root bridge as learned in configuration
messages. This time is used in designated bridges.
A count of topology changes in the network, as detected on this bridge through link failures
or as signaled from other bridges. Excessively high or rapidly increasing counts signal
network problems.
