Compatibility mode

The following table shows how the v2 zl and zl modules behave in various combinations and situations when Compatibility mode is enabled and when it is disabled.

Compatibility mode enabled/disabled comparisons

Modules

Compatibility mode enabled

Compatibility mode disabled

v2 zl modules only

Can insert zl module and the module will come up. Any v2 zl modules are limited to the zl configuration capacities.

v2 zl modules are at full capacity. zl modules are not allowed to power up.

Mixed v2 zl and zl modules

Can insert zl module and the module will come up. Any v2 zl modules are limited to the zl configuration capacities. If compatibility mode is disabled, the zl modules go down.

ZL modules are not allowed to power up.

zl modules only

Same as exists already. If a v2 zl module is inserted, it operates in the same mode as the zl module, but with performance increases.

The Management Module is the only module that powers up.

In Compatibility Mode, no v2 zl features are allowed, whether the modules are all v2 zl or not.

If Compatibility Mode is disabled and then enabled, the startup config is erased and the chassis reboots.
