Configure logging

The logging facility stores log messages for events with a specified severity in a

log file. You can change the size of the log file, and the kind of messages

recorded. You can configure the router to output log messages in several ways,

including to a remote router with a specified IP address, or as an email to a

particular email address. The router can also receive log messages from

another router. Set the Logging Facility to log and forward the log messages

you need to monitor your network (see the Logging Facility chapter in the

AR400 Series Router Software Reference). Inspect the log file from time to time,

and if difficulties arise.

Configure Firewall

The firewall facility is enabled with a special feature license. To obtain a special feature

license contact an Allied Telesyn authorised distributor or reseller.

Use the Firewall to protect your network from several kinds of unwanted

traffic or deliberate attacks (see the Firewall chapter in the AR400 Series Router

Software Reference. A special feature licence is required but is enabled by default

on the AR410S and AR450S).

FLASH compaction

If the FLASH memory gets filled beyond a certain level, it will automatically

activate FLASH compaction to recover any space that is made available from

deleted files. You can also activate FLASH compaction manually if required.

While FLASH is compacting, do not restart the router or use any commands

that affect the FLASH file subsystem. Do not restart the router, or create, edit,

load, rename or delete any files until a message confirms that FLASH file

compaction is completed. Interrupting flash compaction may result in damage

to files. Damaged files are likely to prevent the router from operating correctly.

Watch for software updates

From time to time patches may be released to improve the function of your

router software, and new software releases make new features available. Watch

for patches and new software releases on the support site at
