Database Merge Guidelines
Database Merge Guidelines
A database merge refers to a union of the configuration database and static (unlearned) entries in the
active database. See the
CFS Merge Support, page 6-8 for detaileds concepts.
When merging the database between two fabrics, follow these guidelines:
•
Verify that the activation status and the auto-learning status is the same in both fabrics.
•
Verify that the combined number of configurations for each VSAN in both databases does not
exceed 2K.
Caution
If you do not follow these two conditions, the merge will fail. The next distribution will forcefully
synchronize the databases and the activation states in the fabric.
Database Interaction
Table 37-4 lists the differences and interaction between the active and configuration databases.
A and B exist in the
configuration
database,
activation is not
done and devices
C,D are logged in.
1.
You activate the port
security database and
enable auto-learning. configuration database = {A,B}
active database = {A,B, C*, D*}
configuration database = {A,B}
active database = {null}
pending database = {A,B + activation to
be enabled}
2.
You disable learning. configuration database = {A,B}
active database = {A,B, C, D}
configuration database = {A,B}
active database = {null}
pending database = {A,B + activation to
be e
learning to be disabled}
3.
You issue a commit. Not applicable configuration database = {A,B}
active database = {A,B} and devices C
and D are logged out. This is equal to an
activation with auto-learning disabled.
pending database = empty
1. The * (asterisk) indicates learned entries.

Saving the configuration only saves the activated
entries. Learned entries are not saved. Saving the configuration saves all the entries in
the configuration database.
