> # Significance of FCS

> This section lists the significance of FCSs.

> - FCSs support network management including the following:
> - N port management application can query and obtain information about fabric elements.
> - SNMP manager can use the FCS management information base (MIB) to start discovery and obtain information about the fabric topology.
> - FCSs support TE and TL ports in addition to the standard F and E ports.
> - FCS can maintain a group of modes with a logical name and management address when a platform registers with it. FCSs maintain a backup of all registrations in secondary storage and update it with every change. When a restart or switchover happens, FCSs retrieve the secondary storage information and rebuild its database.
> - SNMP manager can query FCSs for all IEs, ports, and platforms in the fabric.
