4.5 Fabric Configuration Information
4.5.1 Certificate
Fabric Manager might be unavailable via Extreme Management Center after
upgrading if the certificate is missing in Extreme Management Center Trust
store.
To ensure Fabric Manager is available, enter the Fabric Manager certificate in the
Extreme Management Center Trust store using Generate Certificate option.
4.5.2 Authentication Key
When you provision authentication keys for Fabric Attach, the key cannot be
read back for security reasons. When the key is read from the device, it always
shows "****". For this reason, it might seem that there is a configuration
mismatch when one does not exist.
4.5.3 Service Configuration Change
If you change a configured service via the Configure Device window that
references one of the following, and then enforce those changes to the device,
the configuration on the device might change unexpectedly:
l MLT
l SMLT
l Port-specific settings to a port belonging to an MLT or SMLT
To prevent this merge, change rows in the Enforce Preview window where MLT
or SMLT are in use from Current to Desired.
To correct the issue after enforcement, modify the service on the device via the
CLI.
4.5.4 CLIP Addresses
Using the CLIP Addresses table in the Configure Device window, you can enter
addresses in both IPv4 and IPv6 formats. However, Extreme Management
Center version 8.4.3 only supports applying a single address (either IPv4 or
IPv6) to a Loopback Interface.
