Backup switch
If your network has many switches, you may wish to keep a backup switch
ready to replace any switch that malfunctions. When you upgrade the software
release or patch on the other switches in the network, upgrade the backup too.
Store on it one current config script for each switch in your network, so that
when it is needed, you need only set the configuration file with which it boots
to match the switch it replaces.
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 switch to output log messages in several ways,
including to a remote switch with a specified IP address, or as an email to a
particular email address. The switch can also receive log messages from
another switch. Set the Logging Facility to log and forward the log messages
you need to monitor your network (see the Logging Facility chapter in the AT-
8800 Series Switch 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 AT-8800 Series Switch
Software Referen ce. A special feature licence is required.
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 switch or use any commands
that affect the FLASH file subsystem. Do not restart the switch, 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 switch from operating correctly.
Watch for software updates
From time to time patches may be released to improve the function of your
switch software, and new software releases make new features available.
