Requirements
Multiple switches in a LAN send log information to the same log host. You can
know the running status of each switch by displaying log information received.
Network Requirements
Analysis
As multiple switches send log information to the same log host, you can set
different values of the facility keyword for each switch to filter information on the
log host, thus avoiding failure in recognizing information source (for example, if
the two hosts have the same name and the facility keywords are set to the default
value local7, you cannot recognize the information source.).
