New and Enhanced Features in AlliedWare Plus 5.4.4 Major and Minor Versions 25
ISSU (In-Service Software Upgrade)
This version does not support ISSU: You cannot use ISSU to upgrade to this minor
software version.
AMF software version compatibility
We strongly recommend that all switches in an AMF network run the same software
release.
If this is not possible, switches running this minor version are compatible with:
■ x210 Series switches running version 5.4.4-1.2 (but not earlier versions)
■ other AlliedWare Plus switches running version 5.4.3-2.6 and later or any 5.4.4-x.x
version.
Upgrading all switches in an AMF network
This version supports upgrades across AMF networks.There are two methods for
upgrading firmware on an AMF network:
■ Reboot-rolling, which upgrades and reboots each switch in turn
■ Distribute firmware, which upgrades each switch, but does not reboot them. This lets
you reboot the switches at a minimally-disruptive time.
You can use either of these methods to upgrade to this minor software version.
For x210 Series switches, you can use these methods to upgrade to this version from
5.4.4-1.2, but not from earlier versions.
For other switches, you can use these methods to upgrade to this version from 5.4.3-2.6
and later, or from any 5.4.4-x.x version.
In summary, the process for upgrading firmware on an AMF network is:
1. Copy the release .rel files for each switch family to the media location you intend to
upgrade from (Flash memory, SD card, USB stick etc).
2. Decide which AMF upgrade method is most suitable.
3. Initiate the AMF network upgrade using the selected method. To do this:
a. create a working-set of the switches you want to upgrade
b. enter the command atmf reboot-rolling <location> or atmf distribute-
firmware <location> where <location> is the location of the .rel files.
c. Check the console messages to make sure that all switches are “release ready”. If
they are, follow the prompts to perform the upgrade.
