Allied Telesis AR400 SERIES Software Release 2.7.1 - Manual (Page 12)

Special Feature Licences
You need a special feature licence and password to activate some special
features over and above the standard software release. Typically, these special
features are covered by government security regulations. Special feature
licences and passwords are quite separate and distinct from the standard
software release licences and passwords. The features that are available and
that require special feature licences depend on region and router model. Some
of the software features that require a special feature licence are:
■ Triple DES S/W
■ DES encryption
■ Firewall SW (enabled on the AR410S and AR450S)
■ Firewall SMTP Application Gateway (enabled on the AR410S and AR450S)
■ Firewall HTTP Application Gateway (enabled on the AR410S and AR450S)
■ IPv6
■ Resource Reservation Protocol (RSVP)
■ BGP-4
■ Load balancer
Most software features that require a special feature licence are bundled into
one of the following special feature licence packs:
■ Advanced Layer 3 Feature Licence
■ Security Pack Feature Licence
For more information about purchasing special feature licences, contact your
Allied Telesyn authorised distributor or reseller. For information on how to
enable special feature licences using the CLI, see “Enabling Special Feature
Licences” on page 20.
Warning about FLASH memory
Before you start to configure your router, note that it is possible to enter
commands that can impact severely on your router’s performance.
DO NOT clear the FLASH memory completely. The software release files are
stored in FLASH, and clearing FLASH memory would leave no software to run
the router.
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.
For more information, see “How to Avoid Problems” on page 125 and “What to
Do if You Clear FLASH Memory Completely” on page 127.
