Q

4.8.1.1

Symbolic Name

A user-defined name of up to 63 characters that identifies the switch.

4.8.1.2

Switch Administrative States

The switch administrative state determines the operational state of the switch. The switch administrative state exists in two forms: the configured administrative state and the current administrative state.

„The configured administrative state is the state that is saved in the switch configuration and is preserved across switch resets. SANbox Manager always makes changes to the configured administrative state.

„The current administrative state is the state that is applied to the switch for temporary purposes and is not retained across switch resets. The current administrative state is set using the Set Switch command. Refer to the ”Set Command” on page A-30.

Table 4-5describes the administrative state values.

	Table 4-5. Switch Administrative States

4.8.1.3

Domain ID and Domain ID Lock

The domain ID is a unique Fibre Channel identifier for the switch. The Fibre Channel address consists of the domain ID, port ID, and the Arbitrated Loop Physical Address (ALPA). The maximum number of switches within a fabric is 239 with each switch having a unique domain ID.

Switches come from the factory with the domain IDs unlocked. This means that if there is a domain ID conflict in the fabric, the switch with the highest principal priority, or the principal switch, will reassign any domain ID conflicts and establish the fabric. If you lock the domain ID on a switch and a domain ID conflict occurs, one of the switches will isolate as a separate fabric and the Port Status LEDs on both switches will flash to show the affected ports. Refer to the ”Set Config Command” on page A-32for information about the switch keyword and the Domain ID Lock and Principal Priority parameters.

If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain conflict occurs, the new switch will isolate as a separate fabric.
