Configuring Syslog Services
308659-14.00 Rev 00
G-3
On each slot, Syslog performs the following functions:
• Polls the local events log buffer to retrieve new event messages
• Selects event messages that meet the requirements of entity filters that you
configure on the router
• Maps the messages it retrieves into Syslog message format
• Inserts a priority code into each reformatted message
• Orders messages chronologically, if you first enabled the message sequencing
feature
• Forwards messages to IP on the router, which in turn forwards messages to
remote hosts identified in the Syslog host table
At a remote UNIX management workstation, syslogd:
• Receives Syslog messages from Nortel Networks routers
• Examines the priority code in each message
• Determines the system handling for each message
• Dispatches each message to any or all of the following destinations:
-- Workstation display
-- Local log file
-- Designated printer
-- One or more remote hosts
Entity Filters
Each protocol and system service in the router software has a unique entity name,
which is contained in each event message originated by that entity. For a complete
list of BayRS entity names and their corresponding internal entity numbers, refer
to the BayRS documentation CD or access the event message database at:
