SCM Primary/Secondary/Tertiary
SCM Primary/Secondary/Tertiary GUIs provide distributed collection and statistics collection
redundancy. SCM redundancy means that the secondary and tertiary SCM collection servers still
continue to collect statistics when the primary SCM collection server is not reachable or completely shut
down. Distributed collection means that you can distribute statistics collection from all switch nodes to
different SCM collection servers. For example, if the connection to the Primary SCM is shut down for
any reason, whether the FTP or TFTP connection has been disrupted, or if the Primary SCM shuts down,
then the Secondary SCM can take over the statistics collection processes. If the Secondary SCM shuts
down for any reason, the Tertiary SCM can take over the statistics collection processes.
P/S/T is always dependant upon the assignment of the collection server. You can use the cnfcollsvr
command to redirect collectors to a CWM host.
