Connectivity Reconciling incompatible software features Earlier releases of software may not be supported in new versions of Fabric OS code. This may be due to a software feature changing or new services being supported. If you suspect that you are trying to introduce a switch into a fabric that has an older version of code, check the release notes to verify that any features on that switch are supported in the fabric with the newer code. When the Management Server (MS) Platform services are enabled on a switch running Fabric OS v7.0.0 and later and you try to merge this switch into a fabric that does not have this feature enabled, the switch does not merge and a segmentation occurs. To resolve this, either turn the MS Platform services off or enable them on every switch in the fabric. In Fabric OS v7.0.0 and later, an ESC frame is used to exchange fabric parameters to detect Enhanced TI Zones, interoperability mode, and Virtual Fabric FID conflicts. If at any point during the ESC frame exchange, a link with incompatible parameters is detected, the switch running Fabric OS v7.0.0 and later does not join into the existing fabric. To fix this issue, refer to the Fabric OS Administrator's Guide for more information on that specific software feature. Brocade Fabric OS Troubleshooting and Diagnostics Guide 50 53-1004126-01

Reconciling incompatible software features
Earlier releases of software may not be supported in new versions of Fabric OS code. This may be due to a software feature changing or
new services being supported. If you suspect that you are trying to introduce a switch into a fabric that has an older version of code,
check the release notes to verify that any features on that switch are supported in the fabric with the newer code.
When the Management Server (MS) Platform services are enabled on a switch running Fabric OS v7.0.0 and later and you try to merge
this switch into a fabric that does not have this feature enabled, the switch does not merge and a segmentation occurs. To resolve this,
either turn the MS Platform services off or enable them on every switch in the fabric.
In Fabric OS v7.0.0 and later, an ESC frame is used to exchange fabric parameters to detect Enhanced TI Zones, interoperability mode,
and Virtual Fabric FID conflicts. If at any point during the ESC frame exchange, a link with incompatible parameters is detected, the
switch running Fabric OS v7.0.0 and later does not join into the existing fabric. To fix this issue, refer to the
Fabric OS Administrator's
Guide
for more information on that specific software feature.
