Starting a topology discovery

You can start a topology discovery on any switch in a fabric. The topology discovery process is as
follows:
1. Each switch in a fabric maintains a list all IE objects in the fabric. When no topology discovery is
in progress in a VSAN, the switch displays the topology discovery status as localOnly in the VSAN.
The switch stores all IE attributes and port attributes of its own but stores only three IE attributes (IE
WWN, IE type, and domain ID) of all other switches.
2. When a topology discovery is started, the switch changes the topology discovery status to
inProgress in the VSAN. The switch obtains the latest IE attributes and port attributes of all other
switches in the fabric and updates them to the local FCS database.
3. When the topology discovery is complete, the switch changes the topology discovery status to
completed in the VSAN. The switch starts an aging timer to specify the amount of time for the
topology discovery information to stay effective before it is deleted.
4. When the aging timer expires, the switch performs the following operations:
Deletes all topology discovery information except its own information.
Changes the topology discovery status to localOnly in the VSAN.
The fabric topology might change. During a topology discovery process, the switch does not obtain the
following attributes:
• IE attributes and port attributes of an IE that joins the fabric after the switch starts obtaining these
attributes of other IEs.
IE attributes and port attributes of an IE that change after the switch finishes obtaining all IE
•
attributes and port attributes of that IE.
