Brocade FC switch


Yes. When cascading a new switch to an existing fabric, it doesn't necessarily need to be connected to a principal switch.
  • In a fabric with one or more switches interconnected by an inter-switch link (ISL) or inter-chassis links (ICLs), a principal switch is automatically elected. The principal switch provides the following capabilities:
    • Maintains time for the entire fabric. Subordinate switches synchronize their time with the principal switch. Changes to the clock server value on the principal switch are propagated to all switches in the fabric.

    • Manages domain ID assignment within the fabric. If a switch requests a domain ID that has been used before, the principal switch grants the same domain ID unless it is in use by another switch.
