To collect debug traces and data either to a file or, if no file is specified to the standard output use the 
command "debug dump virtual-chassis type {trace | data | all} chassis-id <chassis-id> slot {<slot-id> | all} 
[output-file <filepath/filename>]". Example:  
The logs provided complete log about the VC states,VFL linkstates, VC Event-traces,etc.
