You determine how the severity levels of Bay Networks router event messages
map to error levels on your UNIX workstation, based on requirements of the
network management application software you want to use.
See “Configuring Syslog on the Router” on page C-15
for instructions on how to
map router event messages to UNIX system facility and error level codes.
Time Sequencing Syslog Messages
If you enable the message time-sequencing feature, Syslog on each slot:
• Polls that slot for event messages logged since the previous polling attempt
• Filters all event messages retrieved via polling
• Reformats router event messages into Syslog message format
• Forwards Syslog messages to a sequencer gate, which arranges in timestamp
order any messages it receives
• Forwards sequenced messages from the router to the appropriate remote hosts
Without sequencing, Syslog polls, filters, reformats, and forwards messages from
each slot to IP on the router. IP forwards the messages in retrieved order to the
appropriate remote hosts.
Syslog Message Handling on a Workstation
Syslogd on your management workstation uses the priority code in each locally
received Syslog message to:
• Determine that the message came from an external source (a Bay Networks
router in an IP network accessible to the workstation), rather than from an
internal source (such as the workstation’s email system or line printer
spooling system)
• Determine whether to redispatch the message to a local log file, to the
workstation display, to a printer, or to another remote UNIX host
Syslogd makes these determinations by examining the two parts of the priority
code (facility.error) in each message.
