1-34 AR Series Router Reference Manual
Software Release 2.0.1
C613-03018-00 REV A
where
mm
identifies the router model (Table 1-7 on page 1-34) and
rrr
is the
release number (e.g.
761
for Software Release 7.6.1).
There are two methods of providing compressed releases, depending on the
release number of the base EPROMs in the router. For Software Release 7.4 and
later, compressed releases are supported by the base EPROMs and the file
required for a compressed release is:
mm-rrr.REZ
For Software Release 7.2, a special download release is required. The files
required are:
mm-rrrC.REL
mmooDrrr.REL
where
oo
is the release number of the base EPROMs. Releases prior to Software
Release 7.2 do not support compressed releases.
Releases stored in FLASH are subject to licencing. A FLASH release may be
downloaded into the router, but can not be used until the correct licence
information is entered.
Licence information will be supplied by your distributor or reseller with each software
release. For compressed releases on EPROM releases prior to Software Release 7.4, a
separate licence is required for each of the files mm-rrC.REL and mmooDLrr.REL.
The licence is encoded and is specific to a particular router and a particular
release. A licences may be a FULL licence or a 30-day licence. A 30-day licence
will expire after 30 days; a FULL licence does not have an expiry date. To
enable a release licence, use the command:
ENABLE RELEASE
To disable a release licence, use the command:
DISABLE RELEASE
The current status of release licences in the router can be shown with the
command:
SHOW RELEASE
A number of releases can be stored in the router at once. The EPROM release is
always available, and one or more releases may be stored in FLASH. The router
contains INSTALL information that specifies which release (EPROM or one of
the FLASH releases) is to be loaded at boot. This information may be changed
at any time. The INSTALL information can be overridden so that the release
stored in EPROM is loaded.
