Log Destinations
Both event logs and accounting logs use a common mechanism for referencing a log 
destination. 7705 SAR routers support the following log destinations:
• Console
• Session
• Memory Logs
• Log Files
• SNMP Trap Group
• Syslog
An event log can be associated with multiple event sources, but it can only have a single log 
destination.
A file destination is the only type of log destination that can be configured for an accounting 
log.
Console
Sending events to a console destination means the message will be sent to the system 
console. The console device can be used as an event log destination.
Session
A session destination is a temporary log destination that directs entries to the active Telnet or 
SSH session for the duration of the session. When the session is terminated, for example, 
when the user logs out, the event log is removed. Event logs configured with a session 
destination are not stored in the configuration file. Event logs can direct log entries to the 
session destination. 
Memory Logs
A memory log is a circular buffer. When the log is full, the oldest entry in the log is replaced 
with the new entry. When a memory log is created, the specific number of entries it can hold 
can be specified; otherwise, it will assume a default size. An event log can send entries to a 
memory log destination.
