This object specifies which syslog facility code, local_0 through local_7, the device tags its outgoing log messages with when sending them to the log host. Admins set this to match how their central syslog server sorts or routes messages by facility, since multiple devices sending to the same collector often use different facility values to distinguish sources. The default is local_7, which an admin might change to local_3 to group this switch's logs separately from other devices using local_7.
