Information about these modes is stored in the configuration file, as follows:
•
Configuration File Header—Contains the System mode and the Queues
mode (even if these are the default values).
•
Configuration File Body—Contains configuration commands.
System Mode Backwards Compatibility
The following modes have been expanded in the current software version of the
device. Care must be taken when using these features in previous software
versions:
•
Queues Mode—This mode can be changed from 4 QoS queues to 8 QoS
queues. There is no issue when upgrading from previous software versions
that did not support 8 queues, since the 4-queue mode is the default
Queues mode in the current software version. However, when changing the
Queues mode to 8 queues, the configuration must be examined and
adjusted to meet the desired QoS objectives with the new Queues mode.
Changing the Queues mode takes effect after rebooting the system. Queue-
related configuration that conflicts with the new Queues mode is rejected.
•
Stacking Mode—The Stacking mode has been expanded to include hybrid
stacking modes. There is no issue in upgrading from previous software
versions, since the device will boot with an existing stacking mode (Native
Stacking mode). If you want to downgrade software from a device that was
configured in a hybrid stacking mode to a software version that does not
support hybrid stacking, configure the device to Native Stacking mode first.
System Mode and Stack Management
To configure the stack:
Click Administration > System Mode and Stack Management.
The operational status of a standalone device or a stack is displayed in the
Operational Status block:
•
Stack Unit Mode—Displays one of the following values for the device:
-
Standalone—Device is not part of a stack.
-
Native Stacking—Device is part of a stack in which all of the units are
either SG500Xs or Sx500Xs.
